Hello,

I am trying to come up with a way to find which features on different components are concentric in an assembly. For example: tapped hole in one part and cut-extrude in another. Any ideas on the best way to go about this?

My first thought was to select (via API) all of the temporary axes and then check if they are co-axial, but I can't find a way to select them all without selecting the feature first (which would be extremely slow). Unless someone knows how to do this then I need to use some other process.

Any ideas?

Traverse faces of each component

For each face
-->is it cylindrical
-->get the axis
-->get axis vector (transform matrix)

Either compare each axis to a reference vector/axis, or collet them all and see what lines up.

Well, that sounds like an idea. I'll give it a try.

Thanks

If you're getting a ton of cylindrical faces, you can check whether it's a hole or boss with this macro (CodeStack).

Not API way but have you looked into Hole Alignment tool (Tools > Evaluate > Hole Alignment)
