The issue we are having is we linked a dwg survey into our project. We set a sealevel - level which is the distance below what we think will be the finish floor. We did all the adjustments for True North, created Shared Corrdinates and did all the saves. We also need to scale up the linked file to be the correct size for the reported property lines dimensions. 

At one of the elevations we adjusted the Level tags to read Survey Point so we have the correct elvation values. But when we use the Spot Elevation tool we are getting reported values 1/12th the actual value. Why is that? Is there something we can do internally in the project to fix this? Are there work arounds you engage after you have the file linked or imported?

We noticed the Spot Elevation values were 1/12 the actual Level tag values. But adjusting the Spot tag to Relative or Project Base point did nothing to report actual. We tested linking the file into another project and used a custom value at the Import Units setting. That worked. But is there another way after you have done the import?

I think this happens primarly because the DWG file used Decimal units and not Engineering. has anyone else had this same problem?

Thanks,

John

HI John

I check all CAD files prior to importing into Revit.

First i check that the base UNITS are the same - I model in Revit in Metric to base unit MM, so i ensure that all CAD files are also brought in with base unit MM. That ensures that all imports come in with consistant results (in X Y and Z).

The exception for this rule, is that in Australia, all CAD files i recieve from Site Surveyors always come in base unit metric to M scale. So in this instance, i set the import rule in Revit to M so that Revit scale it perfectly for me to MM units upon insertion.

Cheers

David.
