Hi, I have an issue with closing Breps . The final result is generated by joining individual faces and down the row there are some Micro Edges which can be removed by Rhino command “RemoveAllNakedMicroEdges” . However, I can’t find anything in rhinoCommon.dll which does it!

Hi @torabiarchitect , Can you post a model that contains a Brep that works well with this command? Thanks, – Dale

Hi Dale, I attached the model. This is created by a grasshopper plugin which I am working on. If you explode the object and join its faces back, you still get an open object. but after calling the RemoveAllNakedMicroEdges command the object is closed! I can’t find out why and I am not able to simu…

Hi @torabiarchitect , There isn’t anything on RhinoCommon, at the moment, that can help. But I’ve added something that will. Try the new BrepEdgeList.RemoveNakedMicroEdges method in next week’s Rhino 7 Beta release. https://mcneel.myjetbrains.com/youtrack/issue/RH-61026 – Dale

Hi @dale having this method in Rhino 7 is great!, Is there any chance to include this in the next Rhino 6 service pack? our aim is to release the plugin for Rhino 6 .

One of the triangular faces has 4 edges, one of 0 length.

This could be a workaround: for(var i = 0; i < brep.Faces.Count; i++) if (brep.Faces[i].AdjacentEdges().Any(j => !brep.Edges[j].IsValid)) brep.Faces.RemoveAt(i); A = brep.CapPlanarHoles(RhinoDocument.ModelAbsoluteTolerance); torabiarchitect.gh (15.8 KB)

Good to know! I can imagine what is causing this… could you please explain how did you find out ? Actually I exploded the object and look for such a thing , but I couldn’t find …

excellent ! I should first find out what causes the problem in first place, If I can’t then I will try to kill the invalid edges… thanks a lot

Via UI _ShowEdges with Naked edges mode to identify naked edges. _ExtractSrf the adjacent faces. _What each face to get its edge count. If the edge count is more than expected, _DupEdge the edges of the face then _SelShortCrv. (In the case of the face with the extra edge in your model, _DupBorder…

Is there a method for RemoveAllNakedMicroEdges in API?

See if RetrimSrf.py in the post below can repair the faces.
