Locking references in sketches to bodies

Hi,
I can’t seem to figure that out: for a simple example, I’m trying to build a stack of two boxes where the second one is always set in by a certain amount around the sides. So I go ahead and sketch out a rectangle and extrude it. Then I’ll sketch another rectangle on the top face, set the dimension to be a certain distance from the initial box edges and extrude that one too. Now what is not working as I expect are the two following:

  1. Selecting the initial sketch and changing its dimensions changes neither of the two extruded bodies

  2. Moving one of the first body’s faces will not move the second body’s face. I can see that a new sketch curve was created during dimensioning in the second body’s sketch plane which stays at position.

Is there a way to strictly link the sketches and references to the bodies (or vice versa, actually)

  1. Sketches are independent of the 3D bodies that are extruded from them. So once the body(s) are extruded you can delete the sketch or change it in any way you need and the bodies will not be changed

  2. Yes those bodies are also not constrained to each other. Try selecting multiple faces or edges and move those together and maybe that will do what you are trying to do.

Here is an example of what I mean for selecting and manipulating multiple faces or edges:

Well too bad but thanks for the reply. Coming from desktop cad I feel I might have to rethink some

Yes, working in Shapr3D is different than working on desktop or almost any other cad. But once you catch the way it works a lot of things become easier. But not everything.
