Hi Michael,

Just when I think I'm starting to understand this stuff I find I don't.

Using the prefix works great for simplifying object selection.


But I really don't need the prefix in the exported STL files.

So I read about the java script slice function which sounds like what I need to remove the STL_ from the object name when creating the filename for exporting.

I tried an experiment, using the ExportParts command you created for me, but I get an error - cannot find variable "slice".

So I'm guessing to use slice (and others things like it) I need to use something like xxx.slice where xxx is where slice "lives"?
