measure circle diameter

Anonymous — Tue, 07 Jun 2016 02:28:40 GMT

I'm having a really hard time getting fusion to build a tool path for a drill. I'm worried the diameter is wrong. If I select the circle, I get a path length, which I can divide by pi to get the diameter, but is there a way to measure the diameter directly?

Hi @Anonymous,

Thank you for posting the question. Have you tried Measure command? Also, you can check the radius at the right bottom corner of Fusion screen. I hope this helps!

From your description it sounds like it might not be a true circle. I've seen a couple of reasons this can happen. One the hole is at an angle to the surface , if you select the hole surface it will give a diameter. You might have to zoom in real close to select the surface, if you don't the measure tool will select the centre point. The second problem can be the hole was made with a spline and just looks like a circle. In both cases you will have trouble trying to select it in the CAM.

Here's an example of a hole at a slight angle.

Edge selected.

Surface selected.

Excellent point -- that is the problem! I drew the circle in illustrator, imported a dxf and extruded the sketch. I'll draw the circle in Fusion!
