Do you have MSL 3.1 or 3.2.1 loaded? getVersion(Modelica) should tell.

3.2.1

Then do not load the Internal.mo. It is only for MSL 3.1. Skip that or simply call: loadModelica3D()

Thanks, but I still have a problem:

You should have the files in: D:/users/Lewis/Modelica/001_OpenModelica/lib/omlibrary/ModelicaServices 3.2.1 modelica3d/Resources/Include/
If you don't, it might have been fixed in the nightly build.

Thanks,

I don't seem to have a resources folder there. I'll download the new build

Right, I think I'm getting closer, but still have an error:

dbus says its running, and I'm using the new one in the nightly build ...\lib\omlibrary-modelica3d\osg-gtk

It seems we need to make some fixes for modelica3d again... I added a check for an illegal feature used by the library:

[/home/marsj/trunk/build/lib/omlibrary/ModelicaServices 3.2.1 modelica3d/Modelica3D/package.mo:455:5-505:23:writable] Error: Function Modelica.Mechanics.MultiBody.Visualizers.Advanced.Shape.shapeDescrTo3D returns an external object, but the only function allowed to return this object is ModelicaServices.modcount.HeapString.constructor.

Should be fixed in r21083. New nightly builds appear in around 12 hours if nothing breaks them.

Brilliant - it works just fine now.

Thanks for your help
