upcoming meshedit update

we are soon releasing a meshedit update(getting about time) with some new components, as 3DconvexHull, 3Ddelaunay, 3DdelaunayCell, meshweld with color support and some more. If you have any addition which you maybe missing let us know and they maybe can be added.

thanks

Here's how you can collapse an edge identified by vertex indices just using the standard Rhino mesh library. It doesn't let you choose where to position the new vertex though - it always goes to the midpt of the collapsed edge.

However, from what you describe, I must say it sounds like it would be a better option to reconsider the workflow if possible, and try and join the 2 versions of the mesh cleanly to begin with, rather than making a bad mesh and post-fixing it.

Aha...makes sense. Either way, whenever you perform a topological operation on edges with the native rhino mesh class, the edge table gets recalculated, which is pretty problematic when you're trying to execute several changes within a single loop.

It might be easier to identify for your adjacent meshes all naked edges and then rebuild those that share adjacency with a less subdivided mesh.

You might also want to check out Plankton:

It has functions for splitting and collapsing mesh edges
