Choppy Lines when there is a 3D model.

[dsershe1]

Hello community,

I have run into this issue quite a few times, I am wondering if it is avoidable or reversible.

When I open a new AutoCAD drawing, I am able to draw in 2D with no issues. As soon as I start to extrude my 2D parts into a 3D object, I notice my other 2D lines get very "choppy". I have provided two pictures below, comparing the "choppy" lines to the normal smooth" lines". 

Understand this does not happen until I start to extrude everything into 3D.

Hello @dsershe1 

In the command line type in "3DCONFIG" and turn it "ON" and that should solve the problem 🙂

@dsershe1 ,

Try the options in the link:

• Lines appear jagged, sharp, or stepped in AutoCAD

I already tried all of those "solutions" on that page, none of them fix the issue.

@dsershe1  It might look choppy on screen but your prints and pdfs should be fine. The command we use to normally  fix the choppy visuals on screen is regen command.

@dsershe1 ,

Please post an image of the entire screen, showing the entire Workspace and the 3D extruded model (instead of lines) - or post the drawing file.

I am quite embarrassed to admit this, but after trying the regen command (which didn't seem to fix my issue), I realized why this is happening. 

This occurs when I switch between "2D Wireframe" and other Visual Styles. When I switch to "Shaded with Edges", for example, the lines become jagged. Once I switch back to "2D Wireframe", the lines go back to being smooth.

I realize now the reason why I thought it was a 3D Model issue was because I always switch the visual style before I extrude. Sorry to waste everyone's time. I appreciate all the help and suggestions.

It is already on.
