I have noticed that the EnableRedraw method will not only redraw the vieports but also seems to be affecting the layers panel. I can see that the selected layer is ‘flickering’ on each redraw. This is distracting and seems to be slowing down the script. I am in a loop with frequent redraw on/off. Wo…

Hi @Dale , I am revisiting this with more usage and testing of V6. The display speed improvement in V6 is phenomenal, but using what I currently have available via scripting I can’t take the full advantage of it. After more testing I can confirm that the Enable/Disable redraw always causes major slo…

Hi @Jarek , 1.) Rhino.Redraw redraws all views and refreshes the layer panel. Note, this works when screen redrawing is disabled. 2.) Rhino.EnableRedraw True turns on screen redrawing and then (basically) calls Rhino.Redraw. Thus, doing this is: Rhino.Redraw Rhino.EnableRedraw True Will redraw a…

Hi @Dale , The EnableRedraw/Redraw difference is clear (maybe my testing code was confusing since I was trying all combinations to see any differences). The visible slowdown is caused no matter if Redraw, EnableRedraw (or unnecessarily both) are used. Updated Rhino.Redraw will be great to have. So …

[image] Jarek: So it will basically redraw just viewports if such option is selected Yep. – D

Please add this to Python rhinoscriptsyntax as well as scriptcontext.views.Redraw() too please!

Hi @Dale , Just tested the upgraded Redraw method with False for fast redraw. Something seems off… There is zero speed gain / difference whether I use old Redraw of the new one with False for views only. Apart from that, calling Redraw(True or False) seems to be enabling redraw in general. It sho…

Hi @Jarek , I think your test is flawed. Try this: Sub TestJarek Dim nResult, bRedraw, tmStart, tmEnd, i nResult = Rhino.MessageBox("Enable redraw?", 3 + 32) Select Case nResult Case 6 ' Yes bRedraw = True Case 7 'No bRedraw = False Case Else Exit Sub End Select If Not bRed…

Hi @Dale , thanks, and you are right, I was too eager to test it last night and the test did not disable redraw before spinning… here is the fixed test if anyone wants to try: Redraw_vs_EnableRedraw_vs_FastRedraw.rvb (3.1 KB) The new redraw is blazing fast compared to what we had access to before…

@dale , How do I access this improvement in Python? Rhino.Redraw does not exist, even with an import Rhino statement at top. I use doc.Views.RedrawEnabled = True successfully in my Python script so I tried doc.Views.Redraw = False but this fails with the message: Message: attribute ‘Redraw’ …
