Hi all!

I have a curved slot in a TechDraw page. The slot width is constant, and the radius of the slot from the center of rotation is constant. I've attached an image from someone having the same problem in another program.

I can set a radius dimension for the inner or outer edges of the slot, but not the center. I can use the Add Centerline tool to make a center line between two points in the slot, but not an arc. I can make a length dimension to the endpoints of the arc, but they appear like regular dimensions rather than the radial dimension I'm trying to make.

Does anyone have a better solution?
Thanks!

Does anyone have a better solution?

Create a circular arc in the 3D view, and also include it in the TechDraw View, then you can measure it like any other geometrical edge.

Thanks vocx! It turns out it is as easy as adding a sketch and including it in a simple view.
