"-AMASSIGN" COMMAND TO UNASSIGN/DELETE MATERIAL FROM ACTIVE PART WITH AUTOLISP

[babijay43]

Hello all,

Hopefully there's a beautiful mind out there still using this software to help me out.  I have a ton of files that may or may not have a material assigned to it.  I would like to run an Autolisp file at the open of a file that automatically unassigns or deletes a material and density from the "Assign Attributes" dialog box.  Below is a command I've tried, but the problem is that it prompts me to select which part I want to edit.  Is there a way to remove these attributes without having to select anything? 

(command "-amassign" "here I'm prompted to select a part/assembly" "del" "material" "del" "density" "exit")

Can anyone help with this?

Thanks,

Candace
