Rhino 8/9 Bug

  1. Offset Curve – Both Sides
    Works fine in R7.
    In R8/9: extra clicks needed. Minor, but annoying.

  1. R9: GPU Lock / Freeze
    “Revert back to R8” type issue.
    Suspect: object transparency + locked objects.
    GPU (RTX 3080) spikes to 99%. On large files (~250MB), system freezes.
    Not a problem in earlier R9 WIP.

Side note:
Would be nice if R9 WIP by default limited GPU usage to max 90% to avoid freeze.

Turn on solid color: can not choose color, make objects transparent instead.

Instead of an IGS file share the curve as 3dm file.

Also, run the _SystemInfo command in both Rhino 8 and Rhino 9 and share the full results here.

A 3dm file and display mode ini for the second issue would be good too.

Hi Nathan, and thanks for the reply.

I’ve saved the curve in R7.

R7_SystemInfo.txt (2.3 KB)
R8_SystemInfo.txt (2.6 KB)
R9_SystemInfo.txt (2.7 KB)

System Info results for R7-R9.

Regarding the second issue:
The 3DM files are part of an NDA project, so unfortunately I can’t share files or screenshots from it.

As far as I recall, the display mode GreySparkle is a modified version of one of Rhino Bulgaria’s excellent custom viewport modes.

@Joshua_Kennedy the curve given here in Rhino 8 will offset on both sides ok only with distance 0.497. I tried with Offset Through Point on Both sides.

Feedback on R9 - 05.27

All issues remain the same.

-Offset error
-Solid color can not be set
-Locked objects transparency, missing option
-GPU trough the roof

Hi Ja-Ka -

Thanks. I’ve put that issue on the list as RH-87655 Offset: Failure Sample for Both Sides

Please always create new threads for different topics.

Is this something that you can reproduce with factory-default display modes and a simple box in a new file from a factory-default template?

Hi Wim
-Will do!
I mostly use custom viewports and 80% transparency on locked objects in R8. (and R9 until recently) I check later if I can reproduce something with factory defaults, when the transparency option is back in R9. I assume that this situation is only temporary.

RH-87655 is fixed in Rhino 8 Service Release 27
