Updating or Purging a CAD Link

[mojova]

I have a CAD link of a riser diagram in a drafting view and I am trying to make a few changes an reload.  When I reload I keep getting the old file.  I've tried removing the link, I've tried renaming the CAD file and relinking new, I've tried saving as different versions of CAD and it still retains the older file information. 

I ended up copying the content and pasting into a new file and linking new which worked.

Is there some issue with this in 2014?  Is there a way to purge a CAD link completely?

The other frustration is the formatting....looks fine in CAD but once linked in the text shifts or loses width info and looks ****e.   Trust me, I'd prefer to just draw all in Revit from the get go but justifying a seat of Revit for the grey hairs to do riser diagrams doesn't make much sense.

You should be able to go to the Manage Links dialogue box, go to the CAD formats tab, and click the Remove button to get rid of a CAD link.

My initial thought was that you were using Import CAD rather thank Link CAD, but it seems from your original post that you did link it. I'm not sure what would be preventing the CAD file from updating in that case. Are you reloading the link from the Manage Links tab?

A couple of pointers for linking in CAD files like riser diagrams:
1. Don't use RomanS as a font in your CAD files, use Arial, it's the default Revit font.
2. Don't use linetypes with symbols or letters in them, they won't translate to Revit.
3. It's difficult to control halftone in linked CAD files unless you change your print settings. If you need halftoned lines, I would import the CAD link and explode it and use Revit lines so they can be halftoned.
