HINTS & TIPS

Q: Can I draw tangents to circles in EXPERT?

A: Expert supports several options for drawing sophisticated shapes. There are three ways to accomplish this task.

(1) If your circles are of the same radius, you may draw a single-segment wire with end style set to ROUND. In addition, you may convert the wire to polygon.

(2) For drawing any types of circles connected by common tangents, try Rolled Region creation (program must be in all-angle mode). In this mode one can create complicated forms consisting of lines and circular arcs. However, you could refer to the user manual, Sect. 5.3.4.
