Hi Frederick, almost - so what I meant was get rid of all the objectpicker stuff and you can get the selected objects by the return value of moi.geometryDatabase.getSelectedObjects(), like:

var objs = moi.geometryDatabase.getSelectedObjects();

And now that it's selecting objects by name there won't be any unnamed objects selected so I think you can skip the deselectUnnamedParts part as well.

So maybe just this (untested):

function ExportByPrefix() {
mgd.deselectAll();
mgd.selectNamed(pfix);

WaitForDialogDone();

DoExportParts( mgd.getSelectedObjects() );
}


re:
// what are these 4 lines below supposed to do

Those were updating the prompt (the top line in the command options area) by hiding one line of text and showing the next one.
