I have been using ACad since the beginning many years ago. Switched to DS at some point in time.

Problem: a lot of trouble with the PEdit/join not joining the polyline, and the worst problems (but not exclusively) happen when lines are rounded with fillet. Other joining options like PEdit/Multiple join with even 1mm gap tolerance does not work also, and then I have to reopen the drawing for the normal joint to work somewhat. Also the weld command gives unpredictable results (while looking good in DS, other software as our laser cutter places PLine points all over the place).

When I want rounded edges (common with laser), the only solution is drawing circles with tangens/tangens/radius (ttr) which works most of the time, but is very time consuming. This has gone on for years, but I always hoped that the next update would fix this as I figured that a lot of the users would face this problem and flag it, but no luck so far.

This problem has cost me so much time over the last few years that I'm really considering to stop my 2 licenses and switch to ACad (I use Fusion360 also, so this would make sense). Any idea's?
