constraints

[[Ja...]]

I want to measure the radius of a cylinder but I only have about 25 degrees of the cylinder to measure. I want to constrain the location. The only thing I can seem to do is constrain normal vector. I would have thought I want to constrain XY but it won't let me do that.The cylinder space axis is Z. How would you set the constraints for this?

Cylinder won't let you constrain X and Y like you can with a circle.

Maybe create a circle and recall feature points from one of your paths.

Edit Nominal X and Y, then constrain X and Y.

Repeat for other circle paths in cylinder?

A radius constraint can be added to a Cylinder. You will need to constrain the normal vector as well as X and Y to get a result.

Thanks Robert. Learned something new today.

Jason, You can also use Radius Measurement under Size - Standards. This works the same way. On a circle, it automatically constrains X and Y. I have to assume based on Robert's post, that on a cylinder, the necessary restraints are in place as well.

I've attached a sample of results from a cylinder, using 2 circle paths with 5 points each.

Thanks guys, I did eventually figure out that after I constrained the normal vector then it would except the XY constraint.
