Reduce CAD file size before linking

[Chirag Mistry]

I need to link furniture CAD files from my consultants in the revit file. These files are huge (approx 10MB each floor). I have exploded all the blocks, purged, audited, saved the file to a lower version of CAD, but nothing seems to help. I keep getting the following error (ARX_ERROR: eNotThatKindOfClass) I am assuming the consultants are using a third party software that's generating this. Any tips on how best to proceed with large CAD files.

Thanks

Try selecting everything copy, create a new project and paste in there. If that doens't work your not likely to fix the problem.

Chirag - are you running ra2008? As you have AutoCAD is it also 2007/2008 and the drawing file comes up ok? Have you tried dwf or dxf? I know we're all guessing here, but perhaps these latter will remove the ARX issue (dwf or dxf). If the dxf works, you could dxfout then create a new acad dwg and dxfin. Probably would shrink the file and perhaps remove the arx issue.

It might have been build with ADT, like Elmo mention, copy/paste to another project. Purge and audit. Then do it again if necessary

After doing all the explode and purge, rather than saving to a new file, have you tried wblock to a new file? I find often that wblock is the only thing that will "clean" out left over stuff.

FYI: exploding blocks typically makes a file larger in AUtoCAD

Easiest and best way is to wblock your stuff to a new file. That gets rid of any ADT relics.

If you have ADT, the best way to make the file clean is to use the Export to AutoCAD command (available in the File menu of ADT)
