How to get the modelview and projection matrix in Solidworks OpenGL context

Search the API help for transform (Help -> API Help)... According to documentation, ModelView->get_Transform() returns the Model space --> View space transform for a ModelView. . Transform matrices can be retrieved from bodies, components, from sketch-to-model... At first glance it seems that you cannot access the projection matrix via API, so I assume you have to calculate it by yourself from viewpoint parameters.

Hi Heikki,

Thanks for the help. get_Transform actually gives the pixel positions on the screen. I guess I can use Orientation3, Scale and Translation3 to assembly a modelview matrix. Projection matrix is from viewpoint params, that's right, but how to get viewpoint parameters? We do not know camera position or glOrtho parameters.

Thanks!
