Issues displaying imported .dwg files

When importing a .dwg file only 1 layer is visible in Rhino in any view. All layers in Rhino are turned on as are all layers in the original .dwg file. All layers from the .dwg file are imported

Data from other layers has been imported but the curves are not displayed, with care some can be selected and appears as dotted lines, when deselected they disappear. All curves etc are found when selected for deletion with all blocks, hatches curves, dimensions and texts listed and quantified

Any thoughts on a remedy please?

Hi David,

Can you run SystemInfo in the command line and post the results.

I’m not seeing any issues with a quick test. Can you post a sample .dwg ?

Hi Japhy

Apologies for the delayed response

Well, Parallels is not a supported system for Rhino for Windows.

Please post the .dwg so someone can test the import.

This is what I see in your .3dm:

Thanks for looking at the problem

Until recently for the previous 6+months Rhino 7 has performed perfectly with Parallels 18. There has been an upgrade to 19 which may have triggered the issue as may recent Rhino updates. I am reverting to Parallels 18 to see if that helps. I have deleted and reinstalled Rhino 7 it made no difference

Testing the .dwg file uploaded in Top view in all Display modes only dimension lines appear. In Perspective view zoomed out in all Display modes just the dimension lines appear. Zooming in all the curves then appear in all modes

Organic test.dwg (113.2 KB)

Model space objects read: 34, skipped: 9
Paper space objects read: 32, skipped: 0
Block definition objects read: 1344, skipped: 0
XRef objects read: 0, skipped: 0

I don’t know what those 9 “skipped” objects are.

This is what I see in Top view after opening (V7 latest SR, PC Windows 11):

In the file are 28 curves plus 6 radius dimensions (only in the figure at top right)

All the layouts appear to be blank except for the title blocks.

Rolling back to Parallels 18 seems to have sorted the problem

Many thanks for your help!!
