I work with the STEP format. There is a Big problem before me. When I read STEP, I noticed the not all solids were positioned correctly.
I read the list of Shapes from the Step files and each Shape we triangulate by the Mesh function. We see the coordinates of received vertexes have been determined in the local coordinate system of specific Shape. But we would like to obtain coordinates relative to the global coordinate system of the total assembly. Could you please prompt how and from where can we obtain data about position of local coordinate system of Shape relative to the global coordinate system?
