When I export, 3ds max always shows some symmetrical information about the mesh. For example On the far left = Point3(-10,10,...); On the far right = Point3(10,10...); On the top = Point3(0, 20, ...); On the bottom = Point3(0, -20,...); You understand the pattern? Then I google and guessing the cause of it I think the exporter is exporting object space coordinates rather than world So that I need to apply a transformation to it, so that I can get the correct x,y,z in the world space... Am I correct? Thanks Jack

Assuming it's your own code, then the answer is probably yes. If it's a 3rd party exporter, there will probably be some matrix transform there somewhere.

Get the world space matrix from INode::GetNodeTM(). There is also an object offset matrix you'll need to apply - see the docs for INode::GetObjOffsetPos(), INode::GetObjOffsetRot() and INode::GetObjOffsetScale(). You'll then need to concat those matrices together, and use the PointTransform and VectorTransform matrix funcs to get the world space co-oords.
