I would like to link a dwg file into a Revit mass family.

1 . i create the family from the Metric Mass template file.

2. i click File/Import/CAD ....

3. in the box that appears i can import dwg's BUT the "link" option is grayed out.

what did i do wrong ?!

Logic says that Linking imported files into Families (as opposed to projects) would be a bit too tasking as far as computer resources.  The good news is that in order to update all the families in your project, you only need to re import the CAD drawing.  The bad news of course is that it's a bit tedious if you have to do this more than once a month.

The workaround, of course, is creating a revit project to house your linked cad drawing then link that Detail Project into whatever project you need the detail in... I DO NOT RECOMMEND ACTUALLY DOING THIS!!!  But it is a workaround.

Good luck!

well... i need to link it to a family in order for revit to recognize the imported geometry as mass and let me use massing tools to make walls, roofs... whatever from it's faces...

all i really want is to be able to update the family, and in turn my project every time i update the geometry in the DWG file...

any thoughts?!

so... the workflow i want is this

 3d modeling aplication -> Revit mass -> Modeling the walls/windows/etc

and i want it to update all the way AND keep the faces assignments to walls corect... (reimporting does not work, the walls lose their "face information" and the "new geometry" is just that, "new" not the "old geometry updated" like i want it to be.
