Error on Inserting CAD file

[manuelC6NQ9]

Hi everyone Good day!...I would like to inquire regarding on how to resolve the issue on the revit that im working on now, apparently i was going to insert a Autocad 3D file on my revit to resolve the clashes, but it does not work (see attached pic). Can anybody know how to resolve this? Some of my friends told me that its because its a big file, But i doubt that revit cannot take big files, surely there is another problem to this.

instead on insert cad use link cad and see if helps. thanks

[manuelC6NQ9]

I linked it as per your advice but still it shows like this.

Hi,
maybe your Autocad model place too far from base point (from 0,0,0), so try to move it to this point and link cad in Revit again

[aleksandr.b]

And link CAD with this option:

Well, if the whole point of this is to resolve clashes, then I imagine the CAD is going to need to align properly with the Revit Model.  To do this, you can use Specify Coordinates at Point and then Link via Shared Coordinates.  But, I'm surprised you don't already have this information. Or maybe you do.  How were you instructed to align them?  By eye-balling it?

go to your autocad file, when you zoom extend your main drawing is not in the center of you monitor, which means you have objects that are far from main drawing you need to delete that objects, and move your drawings to 0,0 insertion point, before you can link into revit. thanks

You sure about that @ennujozlagam? I wouldn't go there personally. Seems to me that the CAD would already be coordinated with the Revit model if the OP is supposed to use it for clash detection.  Be kind of silly to just give an employee an AutoCAD file out of the blue and tell him to insert into the Revit Model and see if there are any clashes. As it stands right now, the OP can report back that there is no clashes. The AutoCAD elements are miles and miles away from the Revit Model.  😉

@manuelC6NQ9: Did you insert the CAD by Shared Coordinates?  

[manuelC6NQ9]

Yes the CAD is from the the contractor assigned they already coordinated it thru BIM model coordination (and it is placed fine)..Yes i tried both "origin to origin" and "shared coordinates" its still the same.

Yes i checked now the 3d Drawing you are right the drawing is placed so far away from the origin, but my concern is this 3D drawing is supposed to extracted in BIM Model coordination, in the coordination the placement is just fine. Would it still be fine if i move it to 0,0,0?

[aleksandr.b]

Do you try just press OK, when this warning appears?

[manuelC6NQ9]

 I tried your advice to move the CAD model to 0,0...now i can see the structure but it is not aligned in Revit model, Is there any approach in which i can put it in the right position?.

At this point; NO, there is no approach you can use to put it in the "right" position now that you've haphazardly changed the coordinates of the coordinated AutoCAD file.   You can eye-ball it though.

For the DWG file, did you use AutoCAD to  do any purging and Auditing? Also in AutoCAD try WBLOCK out the CAD with the same origin point to get rid of the junk data at the background.
