Newbie question: I am about to make the leap from APTSRN (Another Program That Shall Remain Nameless) to AutoCAD for Mac. APTSRN cannot perform the following task. Create a circle. Duplicate it in place (so that they appear as one). Select any point on the two identical circles, and define a line (in their common plane) that is tangent to the two circles at that point. [Optionally alter the aspect ratio of one of the circles, transforming it into an ellipse, while maintaining contact with the tangent line at that shared point.] Rotate one of the two circles about that tangent line, say 90 degrees (out of the original plane). Use some sort of extrusion or lofting tool to create a surface (or solid) that contains the two circles (the result is expected to be a tube that turns an exceptionally tight corner). APTSRN has long failed to complete this task when the two circles share a common point, presumably because it results in some divide by zero condition in their software. Can AutoCAD for Mac succeed in this task where APTSRN fails?
An a priori thanks for your attention to this matter.
