The latest Rhino WIP (May 16, 2017) contains a large rewrite of the block display code. You should see performance improvements in models that use many blocks (including nested blocks.) This was a large rewrite so I won’t be surprised if there is a bug or two that still need to be squished. Please …

[image] Dmitriy: So, when I modify the block (with BlockEdit) - other blocks in the drawing are shown with an assigned color but should be with gray as all other objects ( being inaccessible). Thanks, I made a bug report for this at Display: Blocks are drawn with wrong color : RH-39…

Steve, what do you think about the line quality here: [image] V6 Display Performance: Block Improvements Serengeti (Rhino 8 BETA) Installed and tested - grin - that’s great, my complex models based on a lot of blocks are fast running now. Also I see the switching to wirefr…

Hi Micha, what do you expect in those areas? I did a quick test with two surfaces AND the split curve is shown in white: (I guess this is what you see as well, that the surface edge and the curves aren’t identically optimized) [image] And here the curve is hidden: [image] And here it is shown …

[image] Micha: Steve, what do you think about the line quality here: I think the quality needs to be improved😀 Is there a couple curve in there as well as surface edges? Curves are not currently using GPU tessellation which is causing slight differences in depth biasing of the wires. Once cur…

Interesting, I see the edge artefacts at my project file, but not at a simple test file. Here a little part that shows the error - no curves in the scene. DisplayIssue2.rar (716.8 KB)

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. [image]

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. Thanks, Dmitriy

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…

Hi @stevebaer Please see example below. Block becomes invisible when I freeze the layer, the block objects belong to. BlockTest_ToSteve1.3dm (242.4 KB) Thanks, Dmitriy

Hi Dmitry - I see that, thanks. https://mcneel.myjetbrains.com/youtrack/issue/RH-39580 -Pascal
