Claim One:
1. The method comprises: generating a three dimensional (3D) model in a 3D model viewer displayed through a machine display through operation of a 3D modeler configured by a 3D model control from a user interface controller, wherein generating the 3D model in the 3D model viewer comprises retrieving the 3D model from a controlled memory data structure through operation of the 3D modeler configured by the 3D model control on a first cloud: configuring a feature mapper with a model feature definition from the user interface controller to define at least one sub-region of the 3D model as a model feature; mapping the model feature to a feature identifier in a mapping table through operation of the feature mapper controlled by the model feature definition; generating an edge wireframe projection of a model view of the 3D model through operation of an output controller configured by an export control received through the user interface controller; determining visible sub-regions associated with model features in the edge wireframe projection through a projection view filter configured with a hidden line removal algorithm; applying the edge wireframe projection to a background layer of a technical drawing displayed through the machine display through operation of a technical drawings viewer, wherein applying the edge wireframe projection to the background layer of the technical drawing comprises configuring the technical drawings viewer on a second cloud to receive a visible features list and the edge wireframe projection from the first cloud; and rendering the feature identifier with a lead line originating from at least one visible sub-region corresponding to an associated model feature in the visible features list on a defined feature foreground layer of the technical drawing through operation of the technical drawings viewer.
