CAD files linked into Revit

Does anyone know why a CAD file (an "EXPORTTOAUTOCAD" Civil 3D file) wont stay in place? I linked in a Cad file its appears in the correct location but when I reopen the Revit model the Cad file has moved. The Revit model has to be in project north in order for the Cad file to come into the correct location using shared coordinates. even if I pin the cad file then close the Revit model and reopen it the Cad file has shifted.

Hi @Anonymous

 

while saving the revit file are you getting any Location Position Changed Dialogue Box.

If so please Select Do not Save option. This might solve the issue.

Yes that wasn't it. Could it be that the site model when publishing coordinates to the Arch model was set to project north instead of true north. Being the fact the site model had the CAD alignment file linked into it; that was used for the coordinate location.

Hi @Anonymous,

 

if you had rotated or aligned the cad to project north then that should be the Case.

I had a similar problem, and I believe this will solve it: 

 

After positioning the CAD file in Revit, acquire the coordinates.  Then publish the location back to the CAD file.  When prompted, save the location back to the CAD file.  This should insure that the CAD file does not shift when reopening Revit.

We have had this issue in the past and found that if we link the CAD file into its own Revit file and link that into the project Revit file it is more stable.  Once the coordinates have been shared it stays in place even after the CAD file gets updated.  It's an extra step but it has stabilized the locations of the separate models and CAD.  We do this for point clouds as well.

Collaboration for Revit does not support A360 Linking of any other file types (IFC, CAD, DWF or Point Cloud). File hosting services like Dropbox and ShareFile may provide a great workaround for this current limitation. These services allows users to create a special folder on their computers, which then synchronizes so that it appears to be the same folder (with the same contents) regardless of which computer is used to view it. The trick for Linking in Revit is that !!!!EVERYONE ON THE TEAM MUST CHANGE HIS OR HER SETTINGS TO A COMMON PATH!!!!.

 

The following steps outline how to make these changes to preinstalled applications.

 

  1. Right click on the Dropbox or ShareFile icon
  2. Move curser to little gear symbol with pull down menu
  3. Select Preferences
  4. Once the Preference box opens change the location where your files sync
  5. Link IFC, CAD, DWF or Point Cloud from this location only and your Links will never need Reloading.
