Do you know, that… ?

The SolidWorks tools (Rate card) You will find hole alignment. It allows you to find in assemblies with the movement of axial holes – ie those, that are not concentric. Just specify the range analysis – Deviations center of the hole and choose Calculate.

attention! implicitly, similar to Interference detection, the software analyzes the entire assembly. If you work with large assemblies, or you want to analyze only selected components, uncheck selected components and select your own.

But that could be used alignment holes, the holes must be made:

• wizard holes
• pulling out cut-outs
• hole surgery
• or duplicate chic

If so you draw element in such a way, that the openings are extrude – they can not be analyzed. Similarly with imported files.

The opening must provide a separate operation!
