Hi, Came across this weird issue today… I’ve been following the examples on Github (specifically, https://github.com/mcneel/rhino-developer-samples/tree/6/rhinocommon/cs/SampleCsCustomRenderSettingsSections ) and copypasting the render settings section classes to my own plug-in. It seems that eith…

Thanks for the information. This explains why i could not reproduce it. The sample projects I have reference the C:\Program Files\Rhino 6\System\ folder where I have the RhinoCommon, Rhino.UI and Eto references of the latest commerical build installed on my computer. The problem is clearly with the…

After further poking around, the same problem seems to arise in the SampleCsCustomSunSections example ( https://github.com/mcneel/rhino-developer-samples/tree/6/rhinocommon/cs/SampleCsCustomSunSections ). Creating a basic CustomSection object and adding it to the sun section with SunCustomSections(Li…

I tried the SampleCsCustomSunSections and it works for me. However I used the latest code and debug build which could affect the issue. I have some questions which could hopefully help to solve the problem. When Rhino crashes do you get a crash dump that we could look at? Also which Rhino release …

Hi Max, Thanks a lot for looking into this. I’m using the latest automatic update of Rhino (6.9.18271.20591, 09/28/2018). The plug-in is using RhinoCommon 6.8.18240.20051 via Nuget. The same problem occurs on a different computer, with - I think - a previous build of Rhino 6. The Windows crash di…

Hi again Max, After some debugging, looks like this is what’s causing problems: Rhino.UI.dll!Rhino.UI.Controls.EtoCollapsibleSection.Rhino.UI.Controls.IWindow.Parent.set(System.IntPtr value) It just loops until it blows the stack. Is there somewhere where I am not setting the correct Eto panel pa…

Hi @tom_svilans , You should not need to worry about setting the Parent. Rhino should take care of all this. This crash seems to be harder then I expected. I tried to build the SampleCsCustomSunSections against 6.8.18240.20051 and then load the plugin in Rhino 6.9.18271.20591, but I was not able t…

One more question: Did this work before or is this the first time you tried to create a custom render section? Thinking about the option if some recent change has broken the custom sections.

Call stack looks like this: [Managed to Native Transition] Rhino.UI.dll!Rhino.UI.Controls.EtoCollapsibleSection.Rhino.UI.Controls.IWindow.Parent.set(System.IntPtr value) Unknown ... Rhino.UI.dll!Rhino.UI.Controls.EtoCollapsibleSection.Rhino.UI.Controls.IWindow.Parent.set(System.IntPtr value) Unk…

I only tried recently to create a custom render section. The very strange thing is that I got the example project to work, but not my plug-in, even after copying the exact same code over. Even then, the example project sometimes chooses not to work, and I’m trying to find out why that is. I did no…

That is a good question as that does not seem to be documented well. That uuid should be the Plug-in uuid It should be the same as the // The following GUID is for the ID of the typelib if this project is exposed to COM [assembly: Guid(“54cc4233-7407-4c76-9422-0b6f01ca802a”)] // This will also be…

Yes I can try to debug what happens in Rhino using your packages.
