Hi all, I am aiming to close a mesh which due to some previous surface modifications (added approximated patch by blending two separate objects) has a number of small gaps at both ends. A closed mesh is required for the subsequent conversion into a solid SubD geometry and modifications in Grasshopp…

Hi @ilmar_ik , That script you copied was meant to be run from the Rhino script editor, not from Grasshopper. Here is a version that is more compatible with Grasshopper: import rhinoscriptsyntax as rs import Rhino def test_match_mesh_edges(mesh): meshobj = rs.coercemesh(mesh) if not meshob…

I also support this request :+1:

This is still in the pile: https://mcneel.myjetbrains.com/youtrack/issue/RH-30345 , although at a low priority.

Hi all, I’m hoping to reactivate this topic. I’d really love to access to MatchMeshEdge in GH. Does anybody know of any updates or is aware of a working script in Grasshopper (Rhino Version 7 SR29)? Best, Coerte

I too would like to use this Thanks, Bathsheba

This issue has been fixed since 7.4 and MatchMeshEdge is now available in RhinoCommon RH-30345 SDK RhinoCommon: Added Mesh.MatchEdges() which calls RhinoMatchMeshEdge

Thank you for looking at this @pierrec . I tried to copy/paste the script into GhPython node, but failing to get any result? Could you show how this can be implemented in GhPython component? I’ve attached a simple GH definition with internalized STL model that is open. Many many thanks, MatchMeshE…

Awesome, thanks! I’ll use it every day. :smiley_cat:

Thanks so much for following up to this request. I feel like I’m missing something obvious here, but the provided Python script returns null. I set the input/output names to match your script and assigned Mesh as the input hint, any idea what I might be missing? I attached a screenshot. Thanks in a…

Hi Coerte, if the input mesh has no edges to match, the result will be null, I guess that’s what’s happening in your case. If you always want a mesh to be returned, you could replace return none by return mesh
