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)
- Check for xrefs and bind them to the drawing, using the Insert option to prevent redundant layers.
- Run SETBYLAYER. This command removes any color, linetype, or lineweight overrides from objects.
- Run PURGE. This command removes any unused layers, linetypes, blocks, and styles.
- Freeze any layers you don’t need.
- Save the Cad file and try linking it again in Revit.
