The technique used to build this model is called edge modeling or poly modeling, which is a derivation of subdivision. In this type of modeling, we have to progressively create edges and faces to build the overall model, which will result in creating a full model. Even if it seems difficult and hard to complete, we have full control over the topology of the model with this type of modeling. It is very important to have control over the topology for models like machines, where the precision and organization of the vertices, edges, and faces can really matter.
The other important aspect of the project, if we look at the concept images, is the fact that this object is perfectly symmetrical, so we can build only half of the spacecraft and mirror the other part.
