Problems with shared coordinates with Civil

I linked in Civil CAD plan using shared coordinates. As Civil plan reference point (the origin of the world coordinates ) is far far away , I get the message/warning below. Civil always uses reference point from the surveyor and the survey point could miles away from the project site. Do we have a work around?

try to clean as much as possible your cad file, it could be some objects that are freeze away from the main drawings and link origin to origin or shared coordinates. thanks

OR refer to this LINK.

Move the Link to the Project Site in Revit, Unclip Survey Point, and Acquire Coordinates of Link. That's it.  No biggie

 

...another workflow would be to bring the Link in Center to Center, move it to the right location/orientation relative to the Revit Model -- then unclip Survey Point and Acquire Coordinates of Link.

Sounds great and I have no problem to bring the CAD plan in REVIT. After I acquire the coordinates from the linked CAD file, the coordinates (brought in REVIT) are way way off the linked CAD coordinates. I thought it might the CAD file messed up so I deleted pretty much everything except for the stair. The result is the same.  The site to its origin over the limits REVIT allowed? So we can only bring CAD into REVIT but not able to share coordinate system with CAD?

I have attached two CAD site plan for your play. Did I miss anything?

I'm not sure what I am to do with these DWGs. Neither one has any Named UCSs from Revit.   In other words, they don't have any Revit Coordinates recorded to them.   However, I went ahead and Linked them both into a blank Revit Project, and set up Shared Coordinates.  I Acquired Coordinates from "site a.dwg", and then Published these Coordinates to "site a_bldg.dwg".  Since the dwgs aren't sharing the same origins, I had to first move the building outline in "site a_bldg.dwg" to the right location on the "site a.dwg" before Publishing Coordinates.  Hope I moved it to the correct spot.

 

Anyways, check out the attached REVISED dwgs and the Revit file in which they are Linked.  NOTE: I didn't bother renaming the dwgs, so don't get them mixed up with the original ones.

The linked REVIT file is correct with coordinates respect to the original Civil plan coordinates. When I link CAD to  blank REVIT file, the coordinates way off. How did you do it? Can you post a video I may follow up clear? Thanks!

I'm not following what you are saying here.  What "linked REVIT file" are you referring to?  

 

When I link CAD to  blank REVIT file, the coordinates way off.

 

Why wouldn't the CAD's coordinates be way off?  A blank Revit file has the it's origin at 0,0,0. Your CAD has it's origin at 1560447.704,174681.207,0.  

 

How did you do it?

 

I did it exactly what I described in my above two posts.  In a nutshell: 1) Linked the Site CAD into Revit Center to Center; 2) Moved CAD so that it the building line work in it was closer to the Project Base Point;  3) Unclipped Survey Point; 4) Acquired Coordinates;  5) Linked the Building CAD into Revit Center to Center; 6) Moved the CAD so that the building line work in it was overlapping the building line work in the first Link; 7) Published Coordinates; 8) SAVED THE PROJECT AND THE POSITIONS.  

 

Can you post a video I may follow up clear?

 

If I get time. But, what I think might be of even more help to you, is the PDF found at this Link:

Thanks!

 

You're welcome.
