Hi,

I am new to Revit and have just started to get to grips with it.

I am wondering if it is possible to constrain revit elements or linked projects onto a linked CAD file and for the constrained elements to then move when the CAD file is changed. For example, on a cad master plan. Is it possible to lock an aligned house type onto a set of lines in cad, then update the cad lines and have the house type automatically re-align to the same cad lines? I have tried this, but once the cad file is changed, the house type in revit does not follow the updated cad link. If this is not possible, is there any other way to make linked cad files and revit work together (like adding co-ordinates to the CAD file), or does this mean that I will have to manually update the revit file each time there is a change?

Using 2011 and 2012 version.

Any help is appreciated and thanks in advance.

The linked CAD file is just a "dumb" file.  If the CAD file changes there is no way for the Revit drawing to automatically update.

Thanks a lot. I guess I will have to manually do the changes then.
