V6 Display Performance: Block Improvements

Objects moved to 0,0,0 - problem is still there. Added a split - split edges are looking fine, touching edges of the model still bad.

Hi @stevebaer

I have tested latest WIP.
One reported issue is fixed (39428)
But the issue indicated earlier (#6) still is not solved.
I will try to prepare a clean example.


Models with heavy blocks now display properly, even in shaded modes with transparency, and strange artefacts that I reported by message are now gone (6.0.17143.8371)
I’m really happy of what I’m seeing here.

On the grasshopper side, there seems to be some trouble though.
When I open my definition, I get a stream of display pipeline warnings…

Hi @stevebaer

Please see example below.
Block becomes invisible when I freeze the layer, the block objects belong to.

Hi Dmitry - I see that, thanks.



@DavidRutten, have you seen these error messages? Sounds like it is GH specific

Can you upload this definition?

I just installed the latest WIP update for Rhino 6 and I am no longer seeing any curves. I opened up a mesh file and was able to see curves there, but in wireframe and in any other mode, like ghosted, I cannot see any NURBS curves or isocurves belonging to NURBS surfaces

Hi Danielle - can you please run SystemInfo and paste the results here?

First things first - update these drivers to a more current version.

Sometimes the blocks are not visible in parallel views. Have any suggestions?
