V7 Selection bug

Rhino

#1

We’re seeing a bug here pretty often when selecting a curve inside an active detail, where selection will pause and we get the spinning bagel for a minute or so until the selection is finally made. I have not been able to reproduce it reliably.

Maybe related, maybe not; selection of objects in a ghosted view is quite slow compared to V6.

Hi Eric - I see the slow ghosted selection in 7 - are the details where the curve selection lags also ghosted, or does it matter?

The last time I experienced, yes the detail was set to ghosted but only line objects were visible in that detail. I uploaded an example file- hopefully you get that.

Hi Eric- I see the file, thanks.

Setting the detail display mode to wireframe does not affect the selection bug.

Hi Eric - I see the delay in selection of the marked curves in the Section page - here there is a noticeable lag but not of spinning-bagel proportions. It seems dependent on zoom - do you see that as well? If I zoom right in to the section of the pipe, selection is normal. Zoomed back out, delayed…

I can isolate just those section curves and see the lag…

Hi PascaI,

I can’t reproduce it here now. I’ll try zooming next time it crops up.

Hi Eric - for the selection lag in Ghosted - it took me a bit more effort than I like to jog my memory but this did come up before - the difference is V7 does a lot of depth-testing to decide what is closer to the camera in the pick - when things get complicated, this can cost more and more time. To trick Rhino for now, in the Ghosted display mode, set a custom grid display to use Transparent

  • even just a little - that setting messes with depth testing so depth testing is turned off in views there there is a transparent grid.

Any better?

Hi Pascal, the grid settings help a lot.

Thanks,
