While developing my latest ERC toy, I got frustrated with the inability to delete the PP2 all at once. Deleting the base part leaves the other 30 pieces scattered around. For my own purposes I rigged up a Python script that recurses through all child's of the base and deletes them, but surely there MUST be a neater way to do it. Is there a keyword in the PP2 for something like "propagatingdelete"? Or is converting to CR2 the only real answer?

Just brainstorming here. When you load a magnet you seem to get three props the magnet, the mag base, and the mag zone. If you delete any one, the lot are gone, perhaps there is a clue here? Also, if you create a minimal figure made of just one polygon, you can parent individual props to it. When the figure is deleted so are the props, but then of course it would have to be saved to a figures pallet, and I'm not sure if this would work with an ERC prop, where it may be necessary that the props are parented to one another.
