Introduction We’re back with a bumper issue for February...um March. From seamless textures to laser scanning we have had our hands full testing and reviewing some essential tools every SketchUp and 3D artist should be aware of. First up we have Vistii, from creator Noel Warren, who has tinkered for over a year with the aim to bridge the CAD/CAM process with SketchUp and is now finally ready to unleash Vistii to the masses. If you are looking to get a model machined without having to fuss about with various applications then I highly recommend checking out our preview of Vistii’s CAM plugin for SketchUp. We’ve also some great articles on Soft Shadows from Dave Richards, Aquarium animations by Adriana Granados. One particular item is the ‘Community PC build’ by SketchUp Expert Pete Stoppel which is bringing big savings to US members in the market for a killer SketchUp rig. Enjoy!

In this example I am just using the sun for light but you could add other lights if you want. Send the model to Kerkythea making sure to tick the box for “Clay” since we’re not using any materials in this model. Once Kerkythea opens, make the following adjustments. For Scene Settings tick the box for Soft Shadows and click OK.

Under Sun and Sky settings go to the second page and change Sky Type to Background Color and make sure the color is black and click Finish.

Now we’re ready to make the render settings and render the image. I use Preset 08.

07

Open PhotoSketcher and open the rendered image. Choose the Pencil Sketch 4 style and adjust the sliders as desired to get the look you want. You can add a paper texture if you’d like. Then hit Draw! You’ll get something like this image. When you’re happy, save the image.

www.sketchUcation.com

08

At some point in this whole process you should also make a Hidden Line export from SketchUp without shadows. I’m using a sketchy line style I created for this and I’m actually making two Hidden Line exports. The first one is at 3000 pixels wide and the second is at 5000 pixels wide.

NOTE: For the second 5000 pixel image export I unsoftened the edges in the curves on the background. Remember, the larger the export size, the finer the lines will appear for a given view or print size.

www.sketchUcation.com

09

So now with the rendered image, the FotoSketcher image and two lines images, it’s time to assemble them. Go to your favorite image editor and open these images. Since the clay rendered image and the FotoSketcher image are at the SketchUp View size, resize the Hidden Line images to that size.

Next go to the rendered image add an additional layer for each of the other images. Set these layers to Multiply. On the layer above the base layer paste the FotoSketcher image. On the layer above that one, paste the larger of the two Hidden Line images. This is the one with the thinner lines. On the top layer paste the remaining Hidden Line image. I also adjusted the opacity for the layer with the thin lines so they are very light.

As an optional thing you can add a bit of color. I applied a “Sepia� preset for this image. To get to this point I probably have no more than 5 or 6 minutes invested in it.

O

nline manufacturing services are nothing new and

have become an integral part of many designers’ resources. It seems though that there are only two manufacturing processes that are readily available online: 3D printing and laser cutting. The reason for this is the CAD/CAM gap. The size of the CAD/CAM gap depends on the manufacturing process. For 3D printing, the gap can be easily bridged. Simply slice a given model through the xy plane all along the z axis and you have the basis for creating the toolpaths to manufacture the workpiece. For laser cutting it is even simpler. The toolpath is just the contour of the 2D shape to be cut.

Cutting edge CAD/CAM applications also have the capacity to import 3D models and automatically generate a strategy to machine them. So, this kind of evaluation can be done automatically, where are all the online subtractive manufacturing services? As it turns out, the CAD/CAM gap runs both ways. The result of these automatic evaluations always differs from the original design to a greater or lesser extent. If the user does not get the necessary feedback on the evaluation, they have no idea what the end product will look like.

Vistii offers an innovative and promising solution to this problem. Their SketchUp plugin essentially extends SketchUp’s status to that of CAD/CAM application. Any solid component inside SketchUp can be manufactured at the click of a

The result appears in Sketchup, both in the WebDialog and the model. The WebDialog shows what is essentially a product that can be added to a shopping basket like any online store. But the product also has 5 check boxes that show and hide different aspects of the workpiece that appears in the model. These are key to understanding what can and cannot be

Vistii allows for the evaluation of any component instance but it pays to have some understanding of machine characteristics and tools available. There are downloadable guides for each machine to help the design process become a process aimed at manufacturing. Vistii is officially in beta stage at the moment, but are actively manufacturing and have a clear view of where the company is heading. All in all, Vistii comes across as a promising solution that brings the power of subtractive manufacturing to SketchUp users’ fingertips. It is great to see a start-up bet so heavily on SketchUp as a platform for their service. According to Vistii founder Noel, “SketchUp is the only 3D program that understands and values simplicity and straightforwardness the way we do. It’s as though we speak the same language.” Check out the video opposite for more details...

fish with sketchup

as interior designers you need a means of animating objects in trimble sketchup. keyframe animation delivers great results quickly

“

www.sketchUcation.com

Adriana’s Books

I

have recently evaluated various plugins for animation in SketchUp and was surprised to realize how often we, as interior designers, need this feature. That is why today I bring you a quick technique using Keyframe Animation by Regular Polygon to animate fish in an aquarium project. Even though this plugin has been mentioned in CatchUp before, I wanted to be more specific and make a short tutorial for the interior design readers. The plugins I evaluated were Proper Animation, which is free, SU Animation from the makers of SU Podium and

Keyframe Animation. The one that offered the most functions is Keyframe Animation. The plugin costs $36 ($28.80 for Premium members) and is also available on a 10-day trial.

View Online

It has the ability to translate, rotate and scale objects, animate subgroups/ subcomponents, assign Keyframe transition times and export these animation to a movie. The plugin can be downloaded from the SketchUcation Shop and you can also find easyto-follow tutorials on the Keyframe companion site.

www.sketchUcation.com

21


The aquarium I used was for a seafood restaurant that I did a long time ago. I placed in the Sketchucation publication section a tutorial that shows not only the fish movements but also how I create the aquarium, the table cloths, the walls and ceiling.

As I said the plugin allows to animate groups and subgroups. Since I wanted to give the impression of a random fish movement I divided my objects into two components. A ‘Cluster Component’ containing 4 fish and a ‘Large Fish Component’ representing a single fish. I copied and scaled the ‘Cluster Component’ to create a small swarm and grouped this as below. These groups were then copied and scaled as needed.

Unfortunately the project was never built but it helped me in this case to study various possibilities for fish movements. The end result still needs some polishing, but it is far enough along to demonstrate its scope and illustrate a combination of translations and rotations. The user need only to generate different groups and then record the initial, the in-between and the final positions.

I also defined a shape that could help me to control the different positions for each group/component in each scene.

www.sketchUcation.com

22


The steps you have to follow are pretty simple: • Create a scene. If you do not want to save the camera settings and want to control the ulterior view position uncheck this option. • Click on the Record button to save the geometric position of the element. • Create another scene. • Move your object to the next geometric position (the translation, rotation or scale that the element have compared with the previous scene). • Click the Record button.

You can continue doing the same process until you achieve the entire animation of your objects.

KeyFrame Animation toolbar is simply laid to allow the quick creation of animations and tweens.

Be aware that the rotation of an object happens in the direction of the smaller angle, so if you want to move 180 degrees or more the behavior will be the opposite as the one expected. For example if you want to rotate 235 grades the object instead will rotate 125 grades.

diminish the speed of these fish moving from one side to the other. Now you can start your animation as you would do it with SketchUp. This is a short video that shows the final results. As I said before it needs to be polished but in the end Keyframe Animation proves to be a great plugin for many of us.

This is another example where the fish only rotate around a center.

I would have liked the option to slow down the motion of my big fish comparing with the rotation but since you only can control the

How does it do it?

defined you can begin to get down and dirty with generating your first seamless texture.

As I mentioned Pixplant uses sliders and marquees to help you to dial in to the result you need. Got a texture skewed at an angle that you would love to use in your current project? No problem just use the ‘Straighten Seed’ feature to select the area you want to straighten and PixPlant spits back a fully adjusted image.

To generate the seamless texture you need to adjust a couple of sliders and click a few checkboxes. It really is that simple. ‘Equalize Seed’ allows PixPlant to uniformily adjust the color and light of the loaded image. Meaning any variations in the pattern are reduced to give you a better visual result.

Need to define a particular area in which to generate a seamless pattern from? Just use the ‘Seed Pattern’ option. This is a nice feature to have especially when an image may contain elements that are not needed in the seamless generation process. For instance, some type of decorative floor tiling that you would need to isolate various areas.

‘Seed Scale’ will scale the result either bigger or smaller than the loaded image. And finally, ‘Extra Seed Symmetry’ allows Pix-

Wait...there’s more! As I menioned earlier PixPlant is no one trick pony. It is also the friend of the 3D visualization artist by also creating all the maps you need to make your renders pop! It adopts the exact same method using sliders and checkboxes. It is a little bit more involved but still pretty much straightforward. Each map, whether normal, specular etc., share what is called a ‘Common Surface Settings’. These are some generic values that affect all the maps and influence the amount of detail on the map surface.

There are also dedicated parameters for each map. So your have optimal control over the depth of diplacement,the intensity of the normal and specular maps and the lighting of the diffuse.

ed to perform these scans without the need for any supplementary hardware or software. SL basically works by pulsing a series of light patterns at the object and building a mesh from this. In comparison to the Starter Kit which involves painting a laser over an object’s surface there’s a huge leap in time saving and ease of use. That being said, setup time intially, for those new to 3D scanning can be somewhat slow. But once you refine the process you would be ready to scan an object within 5 to 10mins. The hardware included to do the SL scanning is substantial. An Acer K11 projector, high quality camera, Hahnel high adjustable tripod, 2 calibration studios and the DAVID software on a USB device. www.sketchUcation.com

The scan... The SLS-1, as mentioned takes some time to setup but you are walked through the process with a supplied User Guide. The hardware assembly is straightforward and the only real head scratching comes when you have to do a bit of physical measuring of objects and distances between projectors, cameras and objects. Once your are ready the DAVID scanning software looks after most things. Projector and camera calibration does mean fiddling with focus rings and aperture settings but it takes longer to type that sentence than it is to do it. When everything is dialled in you can start the scanning process. There isn’t much to do other than click scan and rotate your object on completion. For a full 360 degree scan I found anything between 8 to 12 rotations gave the best results. In the top image you can see the object in the calibration studio, then result of the each pass and finally the completed ‘fused’ mesh.

To take your series of scans and compile them into one mesh the DAVID software has a system called ‘Fusion’ which will automatically align and heal any holes in the scanned mesh and export the result to either .obj, ply or stl. Ideal if you plan to go the 3D print direction.

This UAV has a fantastic specification but at the time of review I was not able the pin-point an exact retail price. I later learned of the price and decided that it was most definitely only for large firms with big wallets. UAVs hold a fascination for me and when time allows I like to play around with my low cost iPhone controlled Parrot AR Drone 2.0, a wi-fi quadricopter.

3D processing With its 16MP high resolution camera, the eBee can capture images with a ground resolution of 3 to 30cm per pixel. Areas from 1.5 to 10km2 can be mapped in a single flight depending on image resolution and flight altitude. The eBee package includes Postflight Terra 3D (a fully automated 3D processing desktop software powered by Pix4D). After the initial data check in the field (overlap control and low resolution orthomosaic), Terra 3D automatically creates a precise geo-referenced orthomosaic and digital elevation model (DEM). Advanced users can further optimize their models through operator defined ground control points and seamlines.

SuSolid resolves the issues. It really is that simple and in most cases it works flawlessly.

SUsolid is very useful in finding problems in my model preventing geometry from being solid. It also helps to fix some of the problems automatically. Its not magic - you need to start with a reasonable model - but the tool makes short work in deleting stray lines, patching holes, and other menial tasks associated with making a model 3D printable.

Surprisingly to me, SUsolid even quickly fixed some errors that I wasn’t able to correct using my old manual methods. The Balance tool is a nice touch, useful for estimating the weight of the model after it has been made solid.

As with most error detecting tools you are bound to run into problems that result in a cycle of error correction. This is really apparent with the Close Holes and Fix Distorted Faces tools.

SuSolid tends to try too hard at times to resolve geometry that is perfectly fine and is already reporting as solid. With the Distorted Faces tool seemingly fixing one problem but introducing another series of errors that when fixed result in another distorted face issue. I tended to stay away from this tool as it did not affect the end result which was to make a non-solid solid. In the image to your left I have analyzed a selection of groups to determine what is not a solid and to overview the errors it is returning. As you can see there is one particular area that has a number of errors from Single Edges to Holes. To target just this item you select it and run Analyze again to perform the fixes needed. On the opposite page you can see the BLUE errors (coplanar edges) took 2 clicks to remove. Fixing the YELLOW error (inside edges) resulted in the RED error (single edges) and fixing this returned a solid. www.sketchUcation.com

54


SuSolid does go above and beyond on the visual feedback. Edge errors are highlighted, non solids are shaded a different colour and it all does make sense on lighter meshes. But when things get denser it can become a bit of a mess to determine where the errors are. Overall the analysis and fixing portion of SuSolid is well thought out and implemented. Whilst not perfect is does do an incredible amount of work that would very labour intensive by hand.

www.sketchUcation.com

55


There are also tools that will group

ungrouped

entities

and divide entities that share a common internal faces into separate groups. These

are

useful

when

trying to disassemble areas from one another and target specific areas for further analysis. The Divide tool can cause SketchUp to become unresponsive but this is a common result when you ask SketchUp to perform any intensive process. The Intersection Check tool will display all the intersections between solid groups and components. It is a non destructive tool but, like the Divide tool, over large selections it can take time to return a result. These 3 tools are a type of pre-check for the Analysis tool. They allow you to group geometry and if there is any internal faces you can divide it further into more groups.

www.sketchUcation.com

56


The final area is to do with assign values to your solids and reporting weights. The toolbar

icons

allow

you

to assign a material type, weight and report the result for each selection. It is a useful feature to determine

the

overall

weights of your solids but in the build I had there seemed no way to assign separate

solids

with

separate

materials

and

return an overall weight. This I felt would allow the user to get a very accurate result when dealing with different materials.

The Verdict Pros + Visual + Ease of use

+ Well executed Cons - Can create errors from fixes

6.5/10

- Poorly documented

Overall, SuSolid is certainly headed in the right direction. It does save you a lot of time and even though there are elements that introduces errors if properly approached you can get the desired results quite quickly.

SketchUp as a Twitter Strategy - Part 3 At first glance, social media can seem overwhelming, addictive, and incredibly time consuming – especially if you’re a project manager working in today’s competitive construction industry. Some might even believe that this new media is only good for constructors (or designers) with nothing better to do except read self-promoting babble in a constant banter of misinformation, mixed with spam and uninformed hype. But they have it wrong.

Social Strategies

In fact social media is what many call “a rich canvas of context,” where messages are linked to brands (aka companies and projects) with stories, events, and transactions visible in real-time conversations that bring valuable insight to project management. It is the way to see the big picture, but it is also a way to eavesdrop on what your competitors are doing. Mining public information, reading posts, and searching keywords and tags helps build strategies for working in the ever changing landscape of the construction industry. In particular, the simplicity of Twitter brings out unguarded exchanges that are telling when seen in the context of a stream of tweets. This includes discovering inadvertent security breaches by marketing staff and employees about current or pending projects. Reading the stream, or timeline, of almost any company’s twitter account brings insights that come with patiently gathering long-range intelligence, generated spontaneously by thousands of short messages. You might think nothing substantive can be said in 140 characters, but add links and pictures and these seemingly Here are some of the Twitter accounts we innocuous little posts begin to reflect regularly read for strategic information: a group consciousness and it doesn’t @Sketchup @AGCofA take long to recognize and evaluate @ReedConstrData @ConstructionMag the collective thoughts exposed by this @Ind_today @GreenBuildNews media. The deeper understanding that @ConstructionNews @edcmagazine @CT_mag emerges from a series of tweets is in @PauleyCreative @constructmgt fact what makes Twitter valuable as a collaborative tool.

Social Security

Security is particularly important to control when posting anything on the internet. Everything, even inadvertent and quickly deleted disclosures, casual comments, or photographs are immediately captured, tagged, and available for future searches. They literally never go away. Most important, there are companies and organizations, like ours, that understand the strategic value of an almost forensic analysis of the data floating around the internet about people, projects, and companies. William Gibson likened this to sifting through the leaves of a forest, gathering information not from one leaf, but all of them as a collective whole. In fact, it’s the unintentional exposures that make it particularly important to keep the information exchanged between team members absolutely private. For reasons many already know, project management is not a public forum. Using Twitter for project management therefore starts with an understanding of the importance of establishing clear policies along with firewalls to guard or even moderate every tweet. Twitter security is simple to set up, but difficult to control in a corporate environment because it is such an immediate, spontaneous, and personal media.

Strategic Searches

A recent survey showed 65% of UK architects and 11 out of 15 of the top homebuilders use Twitter, with 94% finding it useful for a variety of tasks, including keeping up with information and news, networking, and maintaining a strategic awareness of the construction industry in general.

Twitter Basics

Tweet: Account address, @ProjectName. Hashtag: #KeyWord, to view related posts. Mention: @Mention refers to another account. Lists: Divides account into categories. MT: Add to modified tweet, not a code. RT: Add to Retweet, not a code. Message: DM or D, direct message. Blocked: Follower blocked, do not show. Timeline: Account or chronological list of tweets.

http://tinyurl.com/bp7qv34

5 Twitter Security Tips 1. Setup separate Twitter accounts (and Lists) for each project for better control. 2. Protect your tweets by making sure each account is set to Private (geo-locations off). 3. Assign a moderator, not to moderate, but to monitor trends in the tweets. 4. Setup invitation only lists or groups within the account to correlate information. 5. Have a clear social media policy that includes specific Twitter protocols.

It’s important to keep in mind that Twitter is a double edge sword. All tweets are searchable through Twitter, Google, Bing and every other search engine out there. Once found, tweets can be culled, sorted, and sifted by #hashtag, @ Replies, RTs, headers, @Mentions, and text, unless the Twitter account is specifically set for Private viewing. The value of these searches for both internal communications and strategic data mining are clear. Internally there are trending developments, individual and company profiles, collaborations, mentions, startups, and training activities that keep team members informed. At the same time, when viewed externally, tweets put a face on tweeters, including the personal traits and opinions found in occasional disclosures about project preparation, special tools (like SketchUp), or proprietary approaches to problems that may be critical to a successful proposal. The trick is to follow webpages, email, blog postings, and comments to tweets that connect subcontractors and project affiliates whom may respond with deeper insights.

Project Management Tool The value of Twitter becomes increasing obvious after a few days of production, but any idea that Twitter is just for sending, sorting, and searching messages, misses the fact that Twitter is a collaborative tool, especially when photos, library images, and links are added to the kind of discrete information exchanged in real-time in an ongoing process. The goal is to direct group consciousness into group thinking through interactions within a well defined team. This begins in early programming and grows as members are invited into the project’s account as “privileged” followers. This means, the value of Twitter is the media itself. Participating in a series of concise tweets is like feeling the pulse of the entire project team, mashed together into a project long stream of consciousness, that is visible in the flow of precise messages, retweets, and comments, supplemented by scans, photos, video, illustrations, and model images that carry their own perceptive insights.

Twitter Clients

Mobile apps for Twitter vary widely in what they can do. Some are simple and straightforward, while others take a manual to understand completely. Choosing the right app comes down to the one that makes it easiest to immediately access and tweet an image from a library, phone, or tablet.

SMS sends tweets with images and video to accounts using short codes -- 40404 in the United States. Contact codes can be found at Twitter. com. Once the code is synced to the account, text messages are sent and immediately posted to the account. It’s as simple as texting and remains our preference.

Crowd Source SketchUp Here’s the point, when a Twitter group starts with a few people, say the project manager and a principle, they begin a direct exchange of ideas that lasts long enough to work out the direction of basic programmatic issues. As this initial interaction develops, others are invited to join the group, slowly, almost organically. New team members are then invited into this private group to support specific needs, where they can review tweets as insiders, as part of the team. There they are able to see the evolution of thoughts, adding context to other project related documents, and begin to contribute their own ideas – 24/7. They then remain in the group as long as they are able to add value to the team.

Twitter has an app that is even simpler than SMS. Start the app and a menu bar at the bottom of the interface shows four icons: “Home” for your current timeline, “Connect” to track Interactions/ Mentions, “Discover” as the search menu, and “Me” for settings and profiles. Click the New Tweet icon in the upper right corner to tweet and add a picture, video, or library image as you compose your text

Tweetdeck was acquired by Twitter in May of 2011and works pretty much the same way as the Twitter app. Names have been changed to Home, Me, Inbox, and Search, but now you swipe horizontally to access adjacent screens. Image tweets are currently limited to Library Photos and Take Photo, no videos, which eliminates process captures (though videos could be sent via YouTube).

See our books at http://insitebuilders.com

Construction models are important because they are at the visual core of these exchanges from the beginning. Site utilization model images, photo overlays, massing studies, designs, and engineering are gradually mixed with spreadsheets and schedules, along with member comments that have evolved through an exchange of images and ideas. Three dimensional images thereby represent the evolution of the project not as a series of prepared presentations, but as part of a continuous flow of interactions, thoughts, and “social” exchanges. In this, line drawings become three-dimensional groups and components that then transform into shapes and documents as the result of a collaborative effort.

How Oreo Culture-Jacked The Super Bowl (with a timely second screen tweet) http://tinyurl.com/aahnkbg

In other words, collaboration stems tacitly from the flow of comments, micro-posts, seen through the immediacy of a social media. The objective is literally to visually “crowd source” the project from its inception, deeply embedding “buy-in” for team members as a key part of an invited group. In these interactions, ideas are therefore not staged in a meeting, report, proposal, or rendering, but evident as a project that continues to be shaped in an ongoing conversation. In the end, construction models become the focal point that guides a collaborative effort that continues through construction, into facilities management, and finally warranty service long after the structure is finished.

HootSuite adds more complexity. Its menus are Streams instead of Home, a Search function, Stats, and Contacts. HootSuite also makes it possible to manage lists as categories of followers. Use the Compose Menu for tweets, with images limited to Take Photo and Choose From Library, again no video, except through YouTube.

Posterous was also acquired by Twitter last year. It’s the most comprehensive of the Twitter clients -- far more complicated than necessary for most project managers IMHO. Instead of lists, Posterous uses Spaces to divide content. Each Space is actually a micro blog and website. Text and images are posted through tweets, emails, or directly with the Posterous app. The advantage of Posterous and its Spaces is design and customization, allowing long descriptive text along with a range of photos, videos, and illustrations. As a management tool, it’s not a lot different than a blog where every member of the Space can contribute content.

SketchUcation Winter College A Basecamp for Europe

SUMMIT up?

I have mentioned the idea of a SketchUp Winter School here in Europe on a number of occasions to over the past few years. Now, in light of the number emails that I have received from EU based SketchUp users. it looks that it won’t be a SketchUp Winter School, but a SketchUcation Winter School... I am now in talks with parties that are experienced in this area and from what I have learned so far a SketchUcation Winter School could well be one the cards, all be it a joint event with another 3D app support group. Date wise we are looking at Jan / Feb 2014 and it will be a one week low cost, fun filled, skiing / SketchUp and other software training event for approx.. 100 attendees, 30-40 SketchUp users. The cost for the full week, half board (accomodation, breakfast and dinner) will be in the region of ₏600. The destination can be reached via RyanAir and other low cost airlines. Extras would be ski equipment hire and of course some beer money. If you have never skied before, I envy you as you will experience the eureka moment! Even those with leg problems will enjoy the sledging ...... I could well be spending some time in that group ;) Interested folks can email me.
