Align center of surface with center of group

martin_dusek

Hi,
in my assembly, I would like Center1 (which is center of face of Part1) to be coincident (with some offset) with Center of Group1 (Group1 consists of 4 parts which were made by mirroring themselves). Thanks for your help. Martin

if the parts are really that simple, the best way is to just model it all in the same studio and group it once added. If parts 2-5 are in one studio, you could create a mate connector in that studio that you could mate to. Lastly, you may have success if you make a mate connector in the assembly, using the "between entities" mode.

If parts 2-5 aren't moving in the assembly then there are a number of ways including using an offset from one of them... Or as @Evan_Reese says create a mate connector in the part studio.
Unfortunately the "in between" mate connector doesn't allow picking from different parts in the assembly as @Evan_Reese proposed. Don't forget to vote for it here by the way: https://forum.onshape.com/discussion/9722/assembly-mates-allow-mates-between-multiple-instances

There is a work around if you need it to stay centered as things move in the assembly using linear mate relations as shown here but it takes a bit more work to setup:
