Curve display in viewport

[moon161]

ACAD 2007, Curves and splines render correctly in model space, show as straight in viewport. Regen makes no difference.

Any ideas?

By chance did you try Regenall?

Are the curves and splines in 3D?

REGENALL - Didn't work

Curves & Splines - 2D entities in 3D dwg.

What worked- Zoom way in on affected details (so far that you cant see them), then regen.

Tools Menu
> Options (at bottom)
> Display Tab

"Arc and Circle Smoothness" box > can be set as high as 20000

"Segments in a Polyline Curve" box > can be set as high as 2047

That might help.
