Using Rhino3dmIO in Unity problem

#1

I’m trying to use Rhino3dmIO in Unity 5.4 on both Windows and Mac but I’m having issue to use this without an error.

First of all I followed the following instruction to get Rhino3dmIO.dll and rhino3dmio_native.dll from NuGet.

https://github.com/mcneel/rhinocommon/wiki/Rhino3dmIO-Toolkit-(OpenNURBS-build)

Then I put those two DLLs inside Plugin folder in Unity project and I got a following error.

TypeLoadException: Could not load type 'Rhino.FileIO.File3dm' from assembly 'Rhino3dmIO, Version=5.1.30000.14, Culture=neutral, PublicKeyToken=null'.
UnityEditor.EditorTestsRunner.EditorTestsRunnerWindow..cctor ()
Rethrow as TypeInitializationException: An exception was thrown by the type initializer for UnityEditor.EditorTestsRunner.EditorTestsRunnerWindow

And if I tried to run the unity project it just crashes and force quits.

Is there any way to use Rhino3dmIO in Unity?
I did recognized from the following article that while ago somebody succeeded to use this on Unity but I couldn’t figure out how.

Rhino3dmIo is currently only instrumented for Windows. We don’t have an OSX version available at the moment.

#3

It also didn’t work for Unity in Windows platform. Could it mean it’s not supported for Mono?

#4

This could be the problem. We do use mono on OSX for Mac Rhino so I know that it is possible to get RhinoCommon/Rhino3dmIo to work in the mono environment. I have just never looked into this use case.

When the exception is thrown, is there also an inner exception in the exception object? Usually I see those in a TypeLoadException and it is usually more informative.
