Checking concentricity between holes

gil_maor

Hi All, 
I have an assembly and where the parts are connected with bolts.
How Can I check That all of the holes are concentric?
How Can I know If I moved a hole that it is out of alighment.
Currently I am using the "fastened" mate and It affects only one hole.
Thanks!
Gil,

I don't think there's a direct way, but if you have the bolts mated to the first hole, you could check interference to see if the second hole interferes with the bolt.

I made a featurescript that can do this.

All you need to do is create an in-context part studio, and select all of the holes you want to check.
The first hole is the reference hole (which will appear blue).
Holes in-line will appear green.
Holes not in-line will appear red.

I'll create documentation at a future date.
But give it a try, it should solve the problem.

You can get it here:

This amazing! thank you!

@gil_maor, one simple approach is to hide the fastener/s and just measure the distance between mating holes.  In this context "concentric" is just another word for "Parallel Axes Distance  = 0".

Another approach is to change your mating strategy.  Rather than using a single Fasten, apply a Cylindrical mate to one hole and a Revolute mate to another.  If a design change violates concentricity the the mates will blowup.

You might also utilize in-context design (at the assembly level) or multipart Part Studios to establish to build inherent concentricity into your parts.  This 3rd approach carries some risk of unintended consequences for parts widely used in multiple assemblies, or derived in other Part Studios.

Thanks!
I was looking for a method that will not require me to go over each and every hole.

Sorry I did not read you entire reply. 
The second approach is super!
thanks!
