took me ages to find help on these little icons in the subtool pallet, after discovering what they might be,
took a while to figure how to use them.
should be better help on this subject, or organised so you can find info on it easyer.
I looked every where on the subtool help, searched subtool icons, subtool buttons it was only after I thought they might
be boolean operations did I think to search that.
Hard to figure out what it did by just clicking on it. I know that this function is probaly superceded by dynamesh, but yeah.
hope this helps anyone that didn’t know what those buttons did.
