The way I interpret your code is that even though you start out by basing
it on the selection order, you then sort the locators. According to the
layout of your locators in your images, this explains the twisted effect,
since it crosses diagonally from loc2 to loc3. If you do want to control
the order by the selection, then you wouldn’t want to sort it, and instead
preserve the selection order:
locs = cmds.filterExpand(selectionMask=22, fp=True)if not locs:
cmds.warning( "Please select a locator / No locators in selection " )
sel = cmds.listRelatives(locs, parent=True)
points = [cmds.xform(t, q=True, ws=True, piv=True)[:3] for t in sel]
cmds.polyCreateFacet(p=points)
