Fillet Sketch without auto trimming

[alexhardie]

Hi,

I use center rectangle a lot in sketches.  When I fillet a corner on a center rectangle, I lose a bunch of my constraints because the corners get trimmed automatically.  I'd like to be able to fillet sketch entities without trimming the lines.  This would allow me to be able to keep the existing constraints.  If I were to then extrude that sketch, I would simply select the portion that doesn't include the corners, so there's really no need to trim those.  Currently my work around is to only fillet solids.

I would even suggest a counter option of them making it so it still trims the corners, but it maintains constraints.  Either way, definitely a good idea.  Happens to me quite often and I never thought about tossing it up here.

Actually your "Work around" is the recommended workflow and has been for the past 20+ years, keep sketches as simple as possible. Each fillet would add 5 constraints to the sketch, so your filleted rectangle adds 20 constraints. Five of those and you have a hundred extra constraints, then you'll be in the support forum complaining the sketch is slow and uneditable. Yes there are times a fillet in a sketch is needed and in other programs @SolubleSpork 's idea is used, a point is added where the intersection is trimmed away and the lines constrained to the point but it makes a very inefficient sketch.

Adding to the discussion, perhaps including a toggle for dimensions to constrain the new, trimmed, line or the original line length.

I vote for a trim/no trim option.

But regardless of what I like, I found what appears to be a bug related to fillet radius demonstrated in the two screen shots below.  R=62.121 (no trimming)  and R = 62.120 (trim).  I didn't look any further at resolution.
