Merging coplanar surfaces

Hey there Rhino community
A simple one- I can merge coplanar surfaces on a solid but where is the command to merge coplanar surfaces that are not solids just single surfaces -without having to rebuild them. Its one of those questions you think youve done before but cannot for the life of you find it!

Cheers jahn

Hi Jahn,

If the surfaces are planar (and coplanar) you should be able to _Join them first into Polysurface, and then run __MergeAllFaces.


Ahh - there it is- I had to join them in a polysurface first.
