Last up date?

i’m thinking something changed with the last up date ? when i zoom in on geometry in 3d the wire frame and the surface edges get thicker. it didn’t use to do this ?

will you please run systeminfo and paste the results here?

ok, how do i run systeminfo ?

Hello - you can type the command. SystemInfo or use the Help menu > System information.

Do you have GPU tessellation turned on in the OpenGL settings page? I have made changes to how wires are drawn, but also need to determine how your system is set up to be able to tell which routines are drawing the wires.

yep, it has a check in the box,

Ok, that’s good. Does the display look any different if you uncheck this setting?

nope, i just did and it looks the same.

steve, i just figured out what’s going on. i have the rhino options open gl, wire thickness scale set at .5, in the advanced settings page. if i change that back to default, the wire frame and the isocurves are thicker, when you zoom in on something, everything stays the same, it doesn’t change. so, if you change this setting to .5 and zoom on some geometry, you will see it jump to the default thickness. this started happening right after your last update.

Ok, thanks for letting me know. That setting was really intended as a short term hack to see what thickness in general worked for people. Over the past few service releases, the general thickness has decreased a little bit to try and get exactly one pixel thick wires.
