Hiding isolines in sub-object mode

[CarlEye]

I'm working with a Pwr_EditNRB object that was imported from an IGES file, editing its surface materials in preparation for texturing. I've been looking for a way to turn off the isoline overlay that displays on top of the polys, since it severely impacts the frame rate, making the process a lot slower + more frustrating, but I haven't been able to find a shut-off.

Any suggestions?

un checking Display Surface Knots at the bottom of viewport display roll out should solve your problem.

I didn't have surface knots enabled, so that's not the problem. I tried enabling surface knots, but that just ended with Max crashing. :eek: Here's the perspective view + the command panel so you can see the settings. This is in shaded viewport mode, with wireframes disabled.

I'm able to control the granularity of the isoparm overlay with the ISO Line Angle Tol spinner, but this doesn't have much of an effect on FPS. I'm getting about 2fps in Face mode, according to the statistics display. This jumps to about 40fps when I'm out of sub-object mode.

Try turning off edged face mode or try turning selecting the Mesh option at the top of the Viewport Display roll out.

The Crash might have to do with the memory required to display the iso lines on a very complex surface.

Edged Face mode is off (you're referring to the F4 toggle, correct?), + selecting Mesh in the display options only seems to change the way the display looks when I switch to Edged Face or Wireframe mode, at which point full triangulation is displayed instead of isoparms.

This is a pretty complex model, so I don't doubt that the crash was memory-related.
