Hello,

At one time, I thought the number of segments on a refined chamfer was limited to 20? Anyway, as it appears not to be now, there is a problem when adding more that 21 segments to a "Refined Rounded" Chamfer:-

Checked with a new config file.

With 21 segments, it is rounded:-


With 22 segments, the rounded becomes more of a corner:-


Adding more segments makes the corner push out. This is with 30 segments:-


This may be related, so also posting a problem with extude.

Edge -> extrude -> Shoulder style -> Rounded.
When using that function, I expect the extrusion to be rounded, adding more segments to the rounded extrusion is actually removing the rounding off the edge:-

With 6 segments:-


With 20 segments:-


With 30 segments:-

Sorry to resurrect an old thread, but the problem as not been looked at.

Here are some more examples of current problems:-

Creating "Chamfer-> Rounded" on a corner (3 edge intersection):-

Starts to distort of approx 10 segments:-


At 14 segments:-


At 16 segments:-


At 19 segments, the rounded chamfer geometry disappears.

I also see a constant change in size of the radius as the segment number changes.

This is the limitation of the algorithm being used. It is very hard to find a better way.

OK, thanks.

I will find workaround when I need lots of segments.
