Edit > Components to Objects converts all islands of polygons to separate objects in the Model Manager. No selection is necessary.
The parameters are:
Selection radio buttons - specify the fate of the selected region in the original object:
Cut and Paste - eliminates components from the original object.
Copy and Paste - retains components in the original object.
OK button - cuts or copies the components to new objects in the Model Manager and terminates the dialog.
Cancel button - terminates the dialog without creating any new objects.
In the Model Manager, new objects are named the same as the original object, plus -comp-#.
