Automating Joining of All Naked Edges of Polysurface

Rhino Developer

Say I have a polysurface I intend to be water tight, but it has some naked edges I can see via “ShowEdges”.

Manually, I’m able to choose adjacent pairs with “JoinEdges” and, after doing this for a few edges, it’s sealed up.

I’m wondering how I can do this programatically with rhinocommon for a given polysurface with naked edges.

Any suggestions?

Thanks,
Sam

Hi @samlochner,

Rhino has these two functions that might be helpful.

Brep.JoinEdges
Brep.CreateFromJoinedEdges

Hi Dale,

That worked, thanks.

One other quick question for you: I have a brep consisting of a single trimmed surface. I’m trying to rebuild the trimmed surface but while keeping it trimmed. I don’t see the option to retrim like in the command within Rhino. Is it not available or perhaps I’m missing something?

Thanks,
Sam

Hi @samlochner,

No, the build option is not available in the SDK. I’ve make a wish list item to add this option.

The best you can do, at this time, is script the Rebuild command.
