If you want to create plane with utils.facetBox you have to change wallMask:
-x (1), +x (2), -y (4), +y (8), -z (16), +z (32) So, if you need only the bottom of the cube, you should use wallMask=1, or wallMask=2 etc. ______________________________ Anton Gladkyy 2009/12/9 Sergei D. <[email protected]> > > > Second, I generated a simple example in order to be familiar with the > > "python way" of scripting (testGravity_Box.py and testGravity_Facet.py > > attached).
