Draftsight problem
I am drawing files to use with a vinyl cutter. It is best if they are all polylines where possible.
If I draw an elipse and say cut it in half, then join other lines to it. When I make the polyline, the elipse part will not join on. Is there a way round this.
Your help much appreciated.

RE: Draftsight problem
Also are you "snapping to" with the added lines which makes sure the line create closed objects?

RE: Draftsight problem
Polylines cannot contain ellipses. Polylines can only be composed of straight lines and circular arc segments.
I haven't used draftsight so forgive the ignorance of my questions, but some ideas...:
Can you approximate the elliptical curve you want with a series of arc-segments?
Can draftsight create a "SPLINE" instead of a "PLINE"? If you haven't drafted much in certain CAD programs, you may not have had a chance to experiment with SPLINES.
Can draftsight create curves based on an equation? An ellipse is just r^2 = a*X^2 + b*Y^2
Can draftsight "fit" a curve to a sequence of points? If you create 20 points with the equation above, can draftsight connect the dots and smooth the curve?
