Hi - so, currently, I think the only way to combine two component objs
would be to just create a new object with their indices, ie:
sel = [pm.PyNode('myCube.f[0:2]'), pm.PyNode('myCube.f[4]')
indices = itertools.chain.from_iterable(x.indicesIter() for x in sel)
indices = list(indices)
singleComp = pm.PyNode('myCube').f[indices]
Note that you have to cast the iterator to a list for current pymel
releases. However, I just pushed a change to the github repo (
https://github.com/LumaPictures/pymel) which will fix this, and allow you
to pass an iterator in as the indices for a new component object.
I also added in the ability to add two component objects, so you could just
do:
pm.PyNode('myCube').f[0:2] + pm.PyNode('myCube.f[4]')
or
faces = pm.PyNode('myCube').f[0:2]
faces += pm.PyNode('myCube.f[4]')
With my latest changes, you can also do:
faces = pm.PyNode('myCube').f[0:2, 4]
