I have a problem with 'split polygon tool':
when attempting to split multiple(more then one, see attached image) faces at once it does nothing.

In the project I attempt to module a polygon pillar, and I tried to create a square on it's top using the 'split polygon tool'(see attached image).

The tool's settings:
devisions: 1
smoothing angle:0
split only from edges: Y
use snapping points along edge: Y
number of points:1
snapping tolerance:100

I'm using Maya 8.5
CPU:Intel Pentium 4 2.60GHz
RAM:512MB
Graphics card:ATI Radeon 9550

Any help would be appreciated. Thanks in advance,
Benny
