From what I can understand, the Poser manual suggests I can edit existing props by using the Grouping Tool. But I can't figure out how to accomplish trimming clothes.

Basically I just want to know how to trim a pair of long pants so that they are shin length, or make a pair of standard shorts into short-shorts. Morphs haven't been effective for me in this regard, so I want to actually cut the clothing props.

Can someone help out a Poser for Dumbies poster child get started?  Thanks!
