A simple line won't accept color ???

Terry Capps · 6th February 2022, 01:31 PM

I used to be able to create a "line" consisting of two or more vertices and give it a color like Red, but now a line won't accept a color or at least the color doesn't show up on the display. I used the line to create a path for extrusion.

I am running in Windows 11 with an NVIDIA GeForce GT220 graphics card.

Is there something that I need to tweak?

No known problems with a system like that.

Make sure the surface-type is line (otherwise it's a bad polygon).

If the line is selected, it may not show color changes. Press the eye icon (top left of views) to see a clean image with no selection.

Let me know if you still have problems.

I always select "line" for the surface type. The line that I create shows up on the display as gray regardless of what color I select. If I select "surface" mode and then select the line, the message at the bottom of the screen says that the material selected is "3" (if I specified Red).

Clicking on the Inspect (or eye) icon removes grid lines and vertices, but the line still appears gray. Changing the thickness of the line to "2" didn't help.

I think that I am going to try reinstalling AC3D to see if the problem is still there.

It could be a graphics library problem but nVidia libraires are usually excellent.

Perhaps check the control panel for the graphics card and see if any settings jump out as a possible problem. Particularly look for anti-alias being switched on since that can interfere with selection when "select-through" is switched off.

I have tried turning the Anti-Aliasing off, but it didn't help. I have attached an image
of the NVIDIA control panel settings for ac3d. Any suggestions about what to tweak?

They look OK, as far as I can see.

Is this a new graphics card or computer, or OS/Drivers?
