Thanks for the kind words everybody, I really appreciate them =) I just added shift-drag to add to the current selection, control-drag to subtract from it, and have started working on the lasso tool. Finally, I plan on adding a right-click to bring up a popup menu so you can select from material/group/region under where you click, a single facet, or every facet connected to the one you clicked on. It should make selecting things much easier! Steve
