Constraint in assemblies

[koenco]

I have it lots of times that i want to constrain a part symmetric between two planes. The only way i can find is to set a constraint with the distances, so i type in a offset. There must be a way to do this without typing in an offset i guess. See picture: i want to center the small block in the bigger block. Any ideas?

We can't see your image, anyway..

from Inventor 2014 you can use the Simmetry Constraint.

Nice to see this got implemented based on this idea.

Nice work Cadmanto!  

I really use it a lot.

thanks! (thanks too to the developers teams..!)

Yes, looks like a great tool.  I am only on 2013 at work, but have 2014 at home and I can try it there.

Hello, thanks for replies. But the symmetric constraint is not the solution: with this tool you constrain 2 parts symmetrically to a plane. I have only one part to center it in a suare hole of another part. I hope you can see my image now, it's attached. Apparently posting don't work good in Chrome.

What i want to reach is very simple: center the middle block in the other block.

I see what you are trying to do.  A few thoughts, if the idea that I added a link for in my previous posting you can either post a new idea piggy backing that one that speaks to this, or coment on the one I linked here in this thread.

Another thought is to just constrain equally to the edges.  Which is what I think you already have been doing.  Or, create a multibodied part.  Once big square then do the square border around the middle like you show.  Constraining it with dimensions.

What do you mean with "constrain equally to the edges" ? Sounds like this is what i need.

koenco,

Depending of how these were created, have you thought about constraining origin planes?

[koenco]

Yes i did try constraining origin planes, but i hoped there was an easier i function i didn't know of.

[Cadmanto]

What I meant by that was it looked as thought the gap around the middle square was even on all sides.  So I was suggesting the distance contraint all the way round be equal.  Make sense?

Yes i could do a distance constraint, but if i change the block or the hole (make bigger/smaller), the distance stays fixed, and the block isn't in the middle anymore. So i thought on some function to center the block in the hole, and it i change anything the block stays in the center. So distance constraints are not an option as they are fixed. Thanks for helping.
