NX 7.5 Constraints for Spheres

NX 7.5 Constraints for Spheres

NX 7.5 Constraints for Spheres

(OP)
I have NX 7.5 and I need to constrain the center point of a sphere to the center line of a hollow cylinder. The sphere does not touch the inside walls of the cylinder and travels along this center line. I can grab the center line just fine but cannot seem to be able to grab the center point of the sphere. Any thoughts or ideas?

RE: NX 7.5 Constraints for Spheres

Use the "touch align" type and change the orientation to "infer center/axis", you will be able to select the face of the sphere to get the center point (make sure the selection filter doesn't interfere with selecting a face).

Alternately, you can create an object in the sphere part file to help constrain the object such as a point, line, vector, datum csys, etc; then it can be selected in the constraint dialog. This helper object does not have to be in the reference set used for the component in the assembly; but you will have to temporarily switch to the containing reference set before creating the constraint.
