Wireframe doesn't display curved edges correctly

[brandonn3DLHN]

I've been noticing some display errors while 3D modeling circular objects. Some of the lines aren't showing up in certain views in 2D wireframe. I'm using AutoCAD 2018. Please see the attached screenshot. The front viewport isn't displaying the top or bottom edge of the curved surface. The same thing happens when viewing the object in model space. I'm looking for a solution to this problem. Please help.

Hi

Please upload the picture once again (we cant see  the picture).

but try "VIEWRES" and set it up to higher value.

.

i guess it can help ,but for exact answer upload the picture

Good Luck

Thanks for the input. Unfortunately the VIEWRES command didn't work. It displays the circular profile correctly but the outer edge of the solid object when viewed from the side doesn't display correctly. I attached the screenshot to this reply. I'm not sure why the image preview doesn't work but I'm able to download it.

Hi,

can you please try command

_GRAPHICSCONFIG

and turn off hardware acceleration ... does that work?

Is possible and make screen shot from a isometric sw  view  or any angle view,

or by the chance you can upload the cad file.

good luck

Sorry for the delay on this. I still haven't solved this issue. I've attached a few different views of a different part that I'm having the same issues with. There are lines missing in the 2d wireframe visual style but I can still snap to them. The part looks fine in the conceptual visual style but I do most of my modeling in 2d wireframe. Please let me know if you know of a solution for this.

Thanks!

Here's the autocad file. Please let me know if you see any issues with the file. I think it might be an issue with the settings on my computer.

Thanks

Hi Alfred,

I tried that & it didn't seem to work.

Hi,

the missing lines in your view with visual style "2D Wireframe" can be corrected by settings DISPSILH to 1 and then run command _REGEN.

To be able to look to the issue with the non continuous transition between arc and line I would need the dwg-file with the layout that shows this situation. The layouts in that drawing are not prepared for that.

It worked!

I appreciate the help.
