What would be the best way to mate the holes on this servo to the holes on the part under it?

T3WI

I am trying to make it so the holes of the servo are concentric with the holes on the part under the servo without the holes touching each other.

I've tried using a planar mate to constrain the servo to the face of the part, and two cylindrical mates for the holes. The second cylindrical mate causes an error.

Don't know what the best way is. One way is to find the angle between the alignment of the holes of the part you are mounting to and the alignment of the holes of the servo. Then use a Fasten mate, using the dialog within the mate feature to attain the correct orientation. Example below. - Scotty

What you did should have worked. If the second cylindrical mate caused an error, it's possible the holes on the servo, and the holes on the plate, are not the same distance apart. They must be 10000% the same distance. Measure the servo holes, but when the number comes up, click on it to expand it to all of its decimal places. Then put the same number of decimal places on the plate.

A convenient trick: make a sketch on the bottom of the servo, project the holes onto it, put a mate connector on the center of each hole, make sure that mate connector is owned by the servo part. Then the mate connector will be available in the assembly.
