I have a drawing from a customer that has an angle in a box as a basic dimension.It is not called out as angularity.

It is a true position call out on a hole with this angle and a radius to position it.How do I interpret the angle call out

as a basic dimension?Or where can I find information on how to?

Thanks

So the only positioning dimensions on the hole are the radius and the angle dimension?

Sounds like they are using polar coordinates then.

Since there is a positional tolerance on the hole, then the angle and radius are there simply to give you the theoretical exact location of the axis of the hole. This is why they are basic. They have no tolerance. The tolerance is applied through the positional tolerance on the hole and it will give you the tolerance on the axis of the hole.

So, place a cylinder over the axis of the hole with the cylinder diameter being the diameter listed in the positional tolerance block for the hole.

This cylinder represents your entire tolerance area for that hole. The angle and radius dimension just show you where the center of the cylinder is.

There is no tolerance on the angle dimension.
