Can`t edit slabs in Revit 2014

[BananApan]

Hello!

I can`t edit structural slabs in my project, when I try Revit freezes for about 3 min and when it unfreezes nothing has happend. I can`t move or copy slabs either. 

One of my colleagues have the same problem but with structural walls.

Anyone got an idea of what might have happend or have a solution for this?

My revit 2014 is up-to-date

Welcome to the forum!
Please check your graphic card and driver.
If you switch files with your colleague - do you have similar problems.
If you start from scratch - what happens.

Graphic card is also up-to-date.

One of my colleagues are working in the same project with simillar problems. We have made modelgroups for some of the foundation structures which we cant  copy or move. This worked fine before as it was I who placed them there for a while ago.

No error messages appear when Revit unfreezes.

It all worked fine before.

Revit has crashed one time, can that have something to do with it? That the centralfile is corrupt?

After the crash me and my colleague locked eachother with the same elements, we where both the owners of the elements and could not sync our way out of it so we have made a new centralfile and audit it but still the editing problem remains, without the owner lock-ups.

After 2 days we have found a solution for now.

It seemed like it was a level who caused the no-editing-problem. 

My colleague moved the level, on which the walls and slabs where connected to, up and then back to its real height and that seemed to fix it.

Strange how Revit did not give any errors or messages.
