attach wall

[marcknapen]

Attaching a wall with its base to a floor so that the wall is going down to the core of the floor. Why doesn't works anymore in Revit Architecture 2010.
I got an error 'top of the wall is below its the bottom.....'

I can't replicate this problem. Make sure the 'base' option is selected on the options bar. You may be trying to attach the top of the wall to the floor.

So simple ...
I didn't mention the control bar.
Thanks!
