Hi Michael,

Thanks for the help.

You provided the information I needed.

Currently I collect all selected objects with...

var objects = moi.geometryDatabase.getSelectedObjects();

...then de-select them all.

Then I iterate over the collected objects selecting, exporting, de-selecting each one, thus getting one STL file per each initially selected objects.

So instead of selecting each one I have to decide how to identify those objects that should be exported together to the same file.

Thanks again.

Frederick
