CAD file is exploded when liked in the Revit

[Anonymous]

I would like to link a CAD file and use it as a base for my model, But after I linked it, everything is hay wired, lines are everywhere, and seems like exploded.

Hi,

I guess it is because of hight mess in the CAD file. I suggest you linked it by "current view only", that would  automaticly flatten the cad file and maybe solve your problem.

You can also flat the cad file in autocad but i dont think it's essential.

Good luck!

Hello, 

Thanks for the reply.

I already linked it using current view only, and it still the same.

The cad file is one file or it contains Xrefs?

Hi,

It contains exrefs but I already detach everything. Now its only a single file. there where some kind of blocks that are floating. The other part of the file seems fine. Just some blocks are concentrated in a single line in the middle of the drawing.

Hello, open your autocad file in the command prompt type FLATTEN, audit and overkill and try to linked again. If still doesn't work save to another file and explode everything flatten, overkill and audit and linked again your new file and see if helps. Thanks

Actually it looks like the debris field you get sometimes when the CAD is inserted far, far away from the origin.

Yep, it sounds like it.

@Anonymous  open the CAD file, zoom extent and check.

Hi..

your first job is to clean up CAD file..

1. switch on all the layers, unfreeze all the layers..

2.delete layers and stuffs you don''t want.. purge multiple times..

3. zoom extend..

4. Delete any sheets, view ports you have ( cause Revit tries to link sheets first  i.e. viewports, )

5.make sure model space flatten.. check in 3D views to asses..

6.check units ( sometimes its unit-less, change to Meters or mm as per drawings )

7. if there are x-refs, then bind them all, purge..

idea is to keep CAD file as light as possible...

then

in your Revit file, purge, or remove the existing CAD ( same name ) else new cad file

will again convert into existing CAD file type and you will get the same result..

so remove previous CAD link, import and purge...

( sometimes its a good idea to rename the CAD again while linking )

now link the file , choose correct scale, center to center..." current view only "

Best of luck

Hi,

Thank you for your suggestion. I already tried that solution even before you post it here. But still it didnt work.  I found out that the blocks from that cad layout that i want to link in Revit was inserted using an Autocad Plug-In. Thats why it became like that. 

What I did is I plot the layout in PDF. Then I import the PDF into a blank new CAD file. After that I linked it back to Revit. And it works. I guess this is the only solution for this kind of problem.

But Thanks anyways for all the sugesstions.
