Method Modification of Drawing

 

     After constructing the base, you can continue working in the “Design” program and create model constructions. 

    Modeling operations are performed when switching to the “Modifications” tab in the drawing handling mode. These functions are performed before the outline, and then the piece of these outlines, are completely assembled.

      An example of drafting a “tulip”  skirt is shown below. Is it based on a previously drafted project of the skirt base (based on Muller’s methodology). – See Fig.1.
