Reassociate two parts in one

Question

Hello, I have separated these two parts to be able to modify the mesh. Now, I want to reassociate them, but I don't remember how to do it.

    I found ctrl J for join for my last question. Now i have a new problem. In the part Blocking out metal pieces hitredsqdqsdqdqsd.jpghe operation does not go as planned. The inset is not done on the right side on the trunk lid

    Move on Stepane,

    It's going to be a hole anyway, so it doesn't matter on which side it starts:

    If you'd want an Inset on the Linked Cubes, on the 'inside' only, you'd have to Rotate one of them 180° in Object Mode )...and do not Apply the Rotation!)

    I do not understand though, you want to punch a hole but the objects are linked so you are getting two holes? You can always unlink the object data. Can you expand a little more on the question please? 

  • Stéphane Vahle(Injaw) replied

    No, in fact, it's an object data technique. But it's confusing to me. I'm going to go ahead but being Swiss I have too much temptation to want to do things too precisely maybe xD

    Hey Stephane,

    This is something that freaks a lot of people out...

    What we call an Object in 3D, is a Coordinate System (with a per Object name).

    Where (for instance) the Vertices of that Object are in it's Coordinate System, are stored in a list ('Mesh Data').

    If you Scale or Rotate or Translate a Cube in Object Mode, the Coordinate System gets Scaled or Rotated or Moved, but the Vertices' Position stays the same:

    Linking Object Data, means, that you can change the Position, Scale and Rotation of the linked Object's Coordinate System, but the Vertices' Position doesn't change.

    This is something a lot of people struggle with.

    Never thought about it that way but now that you say it, of course, that is why you can change the objects transforms separately from the object data. The data inside the container stays the same while the outside goes through lots of changes.
