VW just stopped rendering Hidden Line

[Matt Basher]

This may be a memory issue, and this file has crashed VW a few times. It is 77MB and has a fair amount of DWG trusses from the Global Truss website. I do modify one of the more memory intensive parts, but the problem is that when I update the viewports, it just ignores the two I am showing here. Skips over them and leaves them in wireframe.

Is there a way to reset these? If I can get them to render Hidden Line one more time I can Convert Copy to Lines and get rid of all the math involved!

Any help is appreciated.

If you reboot, then relaunch Vectorworks and attempt to update just one of those viewports, does it have the same problem?

if so, if you go to Tools > Options > Vectorworks Preferences > Display, what do you have 3D conversion res set to? If you set it to Low (as a test) and then update the viewport, what occurs?

Setting the 3D Conversion Resolution to Low worked. Thank you

I am having the same or similar issue, but the above fix does not work. It is file specific--all SL viewports display Hidden Line correctly, but Dashed Hidden Line looks like wireframe. In render options a dashed line is selected.

Other files render as expected.

Interestingly, after a failed Hidden Line Render, if I simply click on the Open GL option without updating, Hidden Line renders correctly! (Discovered completely by accident.)
