Hi,
I am new to XNA and C# as well. I am using the code from here (http://andyq.no-ip.com/blog/ p=16) to get a bounding box information. However it crashes at when I do the following ->
box = (
BoundingBox)myModel.Tag;I have added the custom importer dll to the properties tab under the content pipeline tab. I cant figure out why its giving this error saying object reference not set to an object.

Hey,
Thanks for the information. Got the bounding box working. Now to only figure out how to get the triangle information out of the model.

It's pretty much the same idea. In your custom Content Processor, override the Processs() method. In there cast the NodeContent input to MeshContent. The following snippet returns a List<Vector3> of each of the positions of the mesh. Then you can do whatever you want with the vertex soup.
private List<Vector3> GetAllVerticies(MeshContent mesh){
List<Vector3> MeshVerts = new List<Vector3>(); for (int g = 0; g < mesh.Geometry.Count; g++){
GeometryContent geometry = mesh.Geometry[ g ]; for (int ind = 0; ind < geometry.Indices.Count; ind++){
// Transforms all of my verticies to local space. Vector3 position = Vector3.Transform(geometry.Vertices.Positions[geometry.Indices[ind]], mesh.AbsoluteTransform);MeshVerts.Add(position);
}
}
return MeshVerts;}
