On a related note, I discovered yesterday that AutoCAD won't let you draw a closed "polyline" object with two sides.
One of the features of the polyline object is that you can turn edges into arcs when you need a curve, and I was trying to make a "D" shape. Had to add a third vertex in the middle of the flat side before it would let me.
- athom 8y agoThat's weird. I remember learning AutoCAD back in the release 10 and 11 days. They used to have this "donut" command that would draw a 2D donut shape using a polyline with thickness, and just two points joined by arcs. Now I think of it, I think I remember: it used two points, with arcs instead of line segments, and "closed" to get the second arc. I'm not sure if you could force the closing segment back to a straight one, but that could have probably got your "D" shape, if so.
- wlesieutre 8y agoI tried it again today and it worked, so there must have been some other reason it was failing. Maybe one of my lines was out of plane? But then I'm not sure why adding a midpoint on the straight edge fixed it. I must have accidentally fixed some other problem at the same time. Here's another odd note though, if you have a polyline with a single arc and use properties to set it to closed, it adds a straight edge and you get a D shape. If you use PEDIT CLOSE it adds another arc to close it instead, and it tries to continue tangent at the end, completing a whole circle.
