They are based on AutoCAD 2016, but will apply to older versions as well as the newer AutoCAD 2017. The lesson format was used in my CAD classes I have been teaching previously. Please note these lessons are for private, individual use as well as public K-12 schools. This is the BEST place to learn AutoCAD for free (and better than most paid.
Isolines are lines drawn on a curved surface to indicate that the surface exists. The Isolines variable controls how many isolines display on curved solids. The default value is 4. A larger number creates a more tightly curved object, as shown here.
Silhouette edges (Dispsilh) are lines that indicate where a curved surface disappears from sight, as shown here. - The Isolines and Dispsilh variables affect the plotting of shapes when the lines are hidden. Facet resolution (Facetres) sets the smoothness of shaded and rendered objects, and objects with hidden lines removed, as shown here.
- Type Regen to display the change, as required.
