OpenGLViewExampleCS can't work with part CAD drawings

Hi, The problem has been fixed, please download the latest CadLib 4.0 version. Also it's better to use the OpenGLExtendedViewExampleCS, because it uses the newer OpenGL rendering pipeline. Thank you for the report! - Wout

but OpenGLExtendedViewExampleCS not working properly

Can you describe the problem? - Wout

private void CalculateModelViewAndProjectionTransform() { if (!updatingTransforms) { updatingTransforms = true; SetTransformations(glGraphics.RenderingContext, transformationProvider, GetClientRectangle2D(), 0d); updatingTransforms = false; } } glGraphics=null

Do you have a call stack? Because there's no problem when I run the application. - Wout
