EXERCISE Finally, we are going to display this structure information in the rhino viewport using a TEXT TAG 3D component. Drop one of these onto the canvas and take a look at its inputs. Most importantly it requires a location (L) for the text - we don’t necessarily have this yet, and the text to display (T) which will be the output of our concatenated strings. Connect this to the T input.

To produce a point to display our structure at, we are going to use some bounding box components. We do this so that if we are trying to display data structure of more complex objects (such as curves or surfaces), the structure information will always be displayed in the corner of the geometries bounding box. Create a BOUNDING BOX component to find the bounds of an object, then create an EVALUATE BOX component to find the point at (0,0,0) in ‘box space’. This will be one of the corners. Lastly, we can connect out PT output from the evaluate box component to the L input of our tag component. Depending on the size of your model you may need to specify a different size for the text using the (S) input.
