I guess next time...

Whoa! I was not aware that these are actually settings. I thought that this dialog: [image: 58f26.jpg] ...listed only video driver capabilities. However highlighting one of the rows DOES indeed change the respective setting. This dialog really should be re-designed using checkboxes! Anyway, your tip already helped on my desktop with an AMD Radeon HD 7700 card. Same on the notebook -- when the Intel HD graphics card is chosen for driving Sketchup. However, when I chose the Nvidia GPU from the Nvidia control panel for powering Sketchup, all the settings in the OpenGL section of the above dialog are ignored. I mean, there are those different rows with different Antialiasing capabilities (like 2x and 4x), but when highlighting one of them, closing that dialog and re-starting Sketchup, lines are still not anti-aliased but look like this instead: [image: wFIfoPp.png] Is there anything else I can do to force antialiasing not only on the Intel HD GPU but also with the GTX 860M CPU?

As long as you know what you do you can combine those hiding possibilities as you like.

You can do the same on the PC but you use Alt.

Great -- that did it. Scaling resolved the problem completely (the final diameter of the rod is only 5mm). Thanks! David.P

Thanks Rocky & Gaieus, amazing -- this of course did the trick even better. Cheers David.P
