Object Snap Tracking
Create a new drawing and set running Object Track to points on Objects Snap Tracking modes to the following; Endpoint, Intersection, Midpoint, Center and Extension. Explain the importance that object snap tracking tools bring during the drawing process. Create a multi-view drawing using the above Object Snap Tracking modes. Object Snap Tracking
Fundamental
Create a new drawing and set running Polar Snap and Polar Snap and Polar Snap Tracking modes to the following; Endpoint, Polar Tracking Intersection, Midpoint, Center and Extension. Explain the importance that Polar Snap and Polar tracking tools bring during the drawing process. Create a multi-view drawing using the above Polar Snap and Polar Tracking modes.
Fundamental
Standard for Lines
Create a drawing that using the ANSI Line Conventions ASME Y14.2M-1992 (reaffirmed 2003). Create a drawing using ISO Line Conventions. Show that the preferred CAD drawing standard contains various line types and width such as; Thick .6 mm and Thin .3 mm line weights. Explain that drawings prepared by a CAD program can be of one line width.

Fundamental
LTSCALE
Review LTSCALE as the global overall scale factor for all lines in a drawing. Demonstrate drawings that use different linetype scales and how to change the LTSCALE system variable.
Control Linetype scales-LTSCALE
Fundamental
CELTSCALE
Review CELTSCALE as the current entity (current object) linetype scale factor. Demonstrate the use or the Properties Palette to change the CELTSCALE (Linetype Scale in the Properties Palette) of a drawing. Demonstrate setting the CELTSCALE to .5 and drawing new lines to differentiate between LTSCALE set to 1 and CELTSCALE set to .5.
