• There are many cases in which it is impossible, in principle, to construct an arc of fillet. The laws of geometry cannot be fooled.
• Narrow long "guts" into which a given mill does not pass, of course, will not fillet - this is simply impossible. To cut off this piece of contour, select 2 non-adjacent segments at the entrance to the gut (by pressing CTRL) and call FP. The program will try to make an arc between these segments and erase an impassable section of the contour.
• The program does not attempt to lengthen segments before fillet. If the specified diameter is insufficient to reach from the end of one segment to the beginning of the second, then fillet will not be built.
• The program does not check the contour for bottlenecks. Perhaps there will be areas where the mill just does not fit. Check the resulting circuit using the _Offset command.
• It is noticed that sometimes the _Offset command cannot process a polyline built by a program. This sometimes happens when the Offset must absorb one of the fillet arcs. Try slightly increasing the radius of the arcs (just pull the middle point to the ends of the arc) - this helps.
