Python examples

import maya.cmds as cmds

cmds.curve(d=3, p=((-9.3, 0, 3.2), (-4.2, 0, 5.0), (6.0, 0, 8.6), (2.1, 0, -1.9)), k=(0, 0, 0, 1, 2, 2));
cmds.paramDimension( 'curveShape1.u[0.5]' )
# displays where u = 0.5 is on the curve
cmds.sphere();
cmds.paramDimension( 'nurbsSphere1.uv[0.5][0.5]' )
# displays where u = 0.5 and v = 0.5 is on the surface
