Currently I only know of one way to join meshes - using the join operator:
This has an annoying overhead of additional operations required to select the objects you want to join, etc.
But what if I only want to join elements from two different meshes? This will be even more cumbersome with traditional methods: select the object, go to edit mode, select the relevant elements, duplicate them, separate them to a new mesh, join the new mesh with the other mesh...
It would be much nicer if I could just create two bmesh objects, then directly copy elements from one to the other. Something like this currently illegal code:
for v in bm1.verts: bm2.verts.add( v ) # or: bm2.edges.add( bm1.edges )
At the moment this requires adding the vertices first via their coordinates, then adding faces or edges by referencing the relevant new verts.
# Example for adding all the edges from another bmesh object current_last_vert_index = len( bm2.verts ) - 1 for v in bm1.verts: bm2.verts.new( v.co ) for e in bm1.edges: verts = [ bm2.verts[ current_last_vert_index + v.index ] for v in e.verts ] bm2.edges.new( verts )
So, any better way to do this?
