I have problem to show up the blue control line in OpenGL Engine but if I switch to Vectorial Engine, I can see the blue control line. Can someone solve this problem? Please refer to attached images. Thanks.

I am not aware of any settings specifically for OpenGL.
There is a Work Environment settings to show selection contours and reference lines, but this affects OpenGl and Vectorial engines.

I would check that you have the latest video card drivers installed.

Hi Barry, thanks for your reply. I haven't found the right answer for this problem, but I have a solution here. I saved as the model to AC 20 and re-open in AC 21, I don't have this issue anymore. I guess this may cause by the railing and stair tools as they don't show up in the new model.

Railings and stairs would have been deleted when you saved back to 20 as those tools don't exist in 20 and can't be replicated - so they just get deleted.
I doubt it was anything to do with them.

Sounds like it was just a glitch that got reset when saving back.
I still have no idea what it could have been.
