Rong, Sounds like a good idea. I think I can construct a Bounds object of BoundingPolytope by 5 planes, which can be used to define a PickBound.
Then, I'll create an instance of PickTool and set its pickShape to the PickBounds created above. (I guess we can't set a random pickShape used by PickCanvas. From its source code, it only uses PickRay, PickCylinderRay and PickConeRay in different situations). I'll try it later, hope it works. Thanks a lot----white >Hi, > >Try the following step >1.
