Maya Python - How do I query the selection to check if only polyVerts or different?

I have a bunch of poly vertex components selected. But sometimes users might select something else along with it (a joint, another mesh, etc.). I'm trying to find a way to test against everything selected to verify it is indeed a vertex. But I can't find anything like this.

Is there a python command to do this directly?

Solution

  • It may be useful for your use-case to use filterExpand with the selectionMask flag set to 31 to return just polygon vertex components from everything that has been selected.

    Following is a simple sample (with some comments): Try it out with different kind of objects and components selected.

    import maya.cmds as cmds

# Will return EVERYTHING selected
all_selected = cmds.ls(sl=True)

# Will filter out and return just the verts
# from everything selected
just_the_selected_verts = cmds.filterExpand(sm=31)

    Check out filterExpand in the docs here.
