scale a cad file to revit file.

[Anonymous]

So I'm not entirely sure how to word this but Ill do my best. I am designing a duct system that I have a fully drawn cad file for, is there a way to scale the cad drawing to the same scale as revit. in essence lets say on the cad file the duct is 6 foot but when I draw a revit duct over it the revit duct is 27 foot. can I make the scales match?

Standard workflow is to draw your object at 1:1 scale (model space). You apply a scale when putting it on a sheet (paper view).

If you have set the units properly then it would import in Revit at the right scale.

If this is not the case you can correct it when linking/importing it in Revit. During the import you have settings and multiplication factors to correct it

Check the units in the CAD file.  They're probably metric instead of imperial.
