Join SubD surfaces and extruding them

Hello all,

I’m probably doing something wrong. But i dont seem to be able to join 2 SubD surfaces.

I’m tying to use the join command for this operation.

Another problem i encounter is that i end with an open object after extruding these surfaces.

Any ideas?

Kind regards Reinder

You can’t join a vertex to an edge.

I pulled the two SubD faces apart to make it visually clear that there is a point missing.

This problem can be solved by inserting a point on the red outline.

Next you can use stitch to stitch the points.

Or join, when the vertices are already coincident.
