try laycur
I think it's laymcur.
It is odd, I don't know why they would restrict it to just the model tab unless it was brought over from R12 DOS and never looked at. Anyway, I am running ACAD Map3D 2010 fresh out of the box.
I tried 'laycur' with the following response:
Select objects to be changed to the current layer:
and 'laymcur' with this response:
Select object whose layer will become current:
Anyway, thank you for your help. I think I'll change my PGP to reflect 'LAYMCUR' instead of 'AI_MOLC'.
