ReplaceEdge bug?

When I use replaceedge with selectcurve option on this example, the result is an edge that wraps around a hard corner instead of breaking at the corner.weird replace edge result.3dm (53.0 KB)

Is this repeatable by anyone?

What curve are you selecting as the replacement for the edge?

Isnā€™t there just one curve in the whole file? Hereā€™s a video b/c Iā€™m probably not explaining it wellā€¦

Is this the problem?

If so, then the issue is related to the fact that the underlying untrimmed surface is not big enough to be trimmed by your curve (your curve lies slightly outside the untrimmed surface, causing the gap).

ā€˜duplicate borderā€™, ā€˜untrimā€™, ā€˜extend surfaceā€™ and finally ā€˜trimā€™ with the duplicate border resolves the problem.

The problem isnā€™t that it doesnā€™t quite match the input curve (although I think it should in this case, but maybe thatā€™s a different problem. Also, I think the ExtendSideEdges option should work in this example and it doesnā€™t) The problem is that the resulting surface has an ā€˜edgeā€™ that wraps around a corner. At the end of my video, you can see that I select DupEdge, click on that corner of the surface, and the selection wraps around the sharp edge as if itā€™s a single edge.

Ah, okay. Now I understand.
Anyway I can confirm that this happens even with the extended surface and also with the ā€œangled curveā€ substituted by a degree 1 polycurve (as opposed to the degree 3 in your file).
The edge can be easily split at the corner, but there is definetly something strange happening hereā€¦

Thanks.
Can anyone at RMA replicate this?
