I have a Python script in which I get the BMesh from an existing mesh. Then I want to get the outer edges of the mesh, not the inner edges, mesh could for instance look like this:
I want to get the edges as a sequence that are not in the inside.
Thx for your help.
Edit: Can get the outer edges now like that:
bm = bmesh.from_edit_mesh(obj.data) outer_edges = [edge for edge in bm.edges if edge.is_boundary] for edge in outer_edges: vertices.append(edge.verts)
The only problem I have now is that I want to order them clockwise, any idea for this?
Edit 06.11.2020: Ok ended up with this one here:
bm = bmesh.from_edit_mesh(obj.data) bm.verts.ensure_lookup_table() vert = bm.verts prev = None for i in range(len(bm.verts)): next = None for v in [e.other_vert(vert) for e in vert.link_edges if e.is_boundary]: if (v != prev): next = v vertices.append(obj.matrix_world @ vert.co) if next == None: break prev, vert = vert, next
