Hey, everyone! Is there a way to remove one of trim edge while keep inner loops in C#？
UntrimSpecialEdge.gh (1.2 KB)
do you need this in a more complex scenario or for planar Surfaces only ?
in complex surface not planar, it’s easy to untrim the outer loops in Rhino, but i dont konw how to untrim in C#
my guess you have to rebuild the brep.
As far as i searched, there is no “delete Edge, delete 2d Curve, delete loop” or similar functionality exposed to Rhinocommon
less code and hazzle
- get the inner loops from the surface as 3d Curves
- get the underlaying surface and create a “isSurface” Brep
- Split it with the curves
- search the part, that has all 4 corner points / u-v-Domain min, max
more code, more hazzle, maybe more precision
my recommendation:
follow the first approach and only if there are any problems go the second way.
if nothing works comment with an "AT"Dale - so he might chime in.
kind regards - tom
Thanks bro, extract and resplit is a way, but not efficient because split operation is too slow. Dale said that there are no functions in the Rhino SDK, This is my solution:
1.reconstruct the planar holes surface(easy and quickly)
2. remap it back to the complex surface Brep.CopyTrimCurves.
And SampleCsFaceWithHole.cs seems to work on complex planes as well*？*

I extracted the outer loop of underlaying surface and inner loops of complex surface, then used them to create face with hole, it works unbelievable!!!
RebuildTrimmedSurface.gh (132.0 KB) it works but i dont konw why
