Move Assembly UCS with Autodesk Inventor - Page 2

Step 2
Show all 3 origin work planes. Expand Origin in the browser, and then right click the YZ, XZ, and XY planes and check Visible. Your assembly will look like this.

Step 3
Unground the base part. Right click it and deselect Grounded.

Step 4
Now for the tricky part, which is to constrain the base part to the work planes. If a plane already has the orientation you want, constrain it first. In this case the work plane on the bottom of the Manifold already has the orientation I want, so I’ll add a Mate constraint to it and the bottom of the Manifold first. If you don’t do this the base part can rotate relative to the work planes, and this can make it difficult to add the other constraints.

Once the first constraint is added the other two will be easier. Add Mate constraints with an offset that will center the planes on the part. So your offsets will be half the values you measured earlier.

When you’re finished the assembly will be centered on the origin the way you want it.

Step 5
Now delete the Mate constraints, and then ground the base part.
