Arcs and circles are jagged in layout - fixed in model by viewres

[Anonymous]

Hi. I just opened my Autocad LT in Autocad student version and now all circles and arc are jagged and not curved - i just viewres, regen, regenall etc .. and its fixed in the modeltab but not in layout - how do i get my curved lines back?

@Anonymous,

At Command prompt, type VIEWRES.

Reply "Yes" to fast zooms.

When prompted for "circle zoom percent", the default value should be 1000. If not, try a value of 1000.

Do the arcs and circles look better?

Older versions of AutoCAD used a default value of 100. Most PCs in the last 10 years can handle a VIEWRES value of 1000. Caution though, too high of number will give negligible visual improvement and slow AutoCAD performance.

Let us know if this resolves the issue.

Jerry

It helps in the modelroom but in the layout arcs and circles are still displayed jagged

@Anonymous,

When in a paper space layout, type REGENALL at the command prompt. REA is the default shortcut name.

Does that smooth the arc/circle appearances?

You can also check this setting:

OPTIONS

System Tab

Layout Regen Options

Also, AutoCAD performs a REGEN operation before plotting. Although you may see jagged arcs/circles on screen, they should be smoothed before plotting. Please test this on your system.

Let us know if this resolves the issue.

This fixed the jagged lines in layouts problem for me in civil 3d 2024.
