why does "blend" not work here?

Oi Mike!

You really have to MERGE (this one)

http://moi3d.com/2.0/docs/moi_command_reference10.htm#merge
http://moi3d.com/2.0/docs/moi_command_reference10_German.htm#merge

those edge fragments. JOIN or BOOLEAN MERGE won't do the job here. After that, everything works just fine.

Cheers,
Marco
