I'm trying to do something similar to the 3d door swing which comes with the delivered paz's. I don't seem to be able to hold my mouth right in order to re-create the effect. I know it must have something to do with the directional or planar constraint to a Path2d as well as the positioner setting for the component. But this one boggles me. Can anyone tell me how Bentley did it? I'm attaching the portion of a ABD door which has the 3D opening angle constraint as an example of what I'm trying to do.
