Hi Michael,

-------------------------------------
But how is a special "prefix instead of selection" based export any different than setting the selection by prefix and then using regular selection based export?
-------------------------------------

It's different in that I don't have to keep using the "select by name" feature .

Given a Export command that would select by a pre-established prefix I would just issue the command and the STLs would be exported.

Anytime I want to export, one click - instead of TAB, type the prefix, then issue the Export command.

I update the STL files frequently and since their are all done at the same time they all have the same time stamp in Windows - which is very helpful - to me.
