How to control which geometry moves when changing a dimension

karl — Fri, 04 Dec 2020 00:58:04 GMT

In the attached sketch, I'd like to move the inner rectangle down in the Y direction by .125", so the 1.438" dimension at the top becomes 1.563", without moving the outer rectangle. When I change the dimension to 1.563", the change is accepted but the outer rectangle moves up. I've deleted the coincident constraint at the origin several times, to no avail. I have two questions:

1. How can I achieve my desired result?

2. Both rectangles were created as center rectangles (the outer one first), centered on the origin, automatically creating a coincident constraint each time. When I right-click on the origin and select "Delete Coincident Constraint," how do I know which coincident constraint I'm deleting? How can I delete the other one, whichever one that is?

Thanks.

this is just the way that under-constrained sketches will behave - there is no way to control what geometry moves, other than by adding additional dimensions. That's what I do in the screencast below:

Ah, got it. Thanks!
