Hello,

there is possibility to add constraint UCS to UCS. I'm wonder if is there some easy solution how to constraint two parts in assembly to by their global coordinate system. 

 

I'm not talking about Place grounded to origin. I need to constraint two parts in an assembly to each other by their coordinate systems, but keep them free (stick together, naturally) in the assembly.

 

There are these "workarounds":

  1. Add UCS in same position as GCS in each part (meh) and use UCS to UCS constraint.
  2. Use some basic geometry (Center point, X, Y, Z Axis Planes) of the parts for constraint (lot of click in the tree, more than 1 constraint needed)

Thanks for your replies.

@j.pavlicek I think this is what you are after - (Creates three flush constraints to the origins).

Use iLogic Copy? Please consider voting for this long overdue idea (not mine):https://forums.autodesk.com/t5/inventor-ideas/string-replace-for-ilogic-design-copy/idi-p/3821399

Hi! Another workflow to consider is to use UCS. You can constraint two UCS' by using Constraint Set. Just select the UCS from each component, the two will be snapped based on the UCS.

Many thanks!

Then there's the basic manual method: Mate/Flush constraints XY-XY, YZ-YZ, and XZ-XZ.  That's essentially what the tool does that @gcoombridge recommends.
