Question: Routine for "dancing" dwgs in Revit

Hi!

I guess everyone here have been a victim of "dancing" dwgs inserted into Revit.
Dwgs where the lines are "jumping" and rectangles turning into other shapes etc.
What's your routine for fixing those? I've been a fan of two AutoCAD apps that have been fixing some issues.
Zombiekiller (gets rid of proxies) and Rpurge (radical purge. Purges as much as possible) but I still run into issues now and then.

If importing, then import using Origin to Origin.

Yes, but this usually isn't enough for fixing the problem.
As I understand it DWG files can't be too far from the 0,0 point.
Maybe this is the most common fault for "dancing" files? 
Should a dwg never be in it's correct coordinates but moved with a known coordinate closer to 0,0?

Never seen it. As a rule, I do not insert .dwgs.

Drafting is a breeze and Revit doesn't always work the way you think it should.

DWG with objects too far from 0,0,0 can cause graphic glitches like you described. Open it in AutoCAD, zoom extent and see if you can get rid of those objects. When link it in Revit, if Origin to Origin causes trouble, use Center to Center.

Hi @Marcus.Isacsson

Sorry to hear that you are facing graphic glitches in Revit.

 

A few questions for you:

Which version of Revit are you using?

Is this dwg file a survey drawing? Did you explode the dwg?

Is your graphics card updated with latest driver from the manufacturers' website?

 

Some options to try:

  • Try inserting the files with the 'center to center' option, with manually re-positioning and pin it. (click the option 'Correct Lines That Are Slightly Off Axis')
  • If you still continue to face these glitches, try importing your dwg file as a 2D drafting element family
  • Linking is preferred because it does not bring in any unwanted exploded objects which can get converted to Revit elements.
  • Do a fresh clean up of your cad file (recommended before you link)
  1. Check for xrefs  and bind them to the drawing, using the Insert option to prevent redundant layers.
  2. Run SETBYLAYER. This command removes any color, linetype, or lineweight overrides from objects.
  3. Run PURGE. This command removes any unused layers, linetypes, blocks, and styles.
  4. Freeze any layers you don’t need.
  5. Save the Cad file and try linking it again in Revit.

@Viveka_CD and we must not forget to run the OVERKILL command to clean up our DWGs before linking into Revit!

@Sahay_R Thanks for the heads-up!
