Blender is a trusty 3D Swiss army knife that makes all of this modelling possible. So, since we’re moving from 2D to 3D, we’ll need to update some of the utility scripts we wrote previously for data import and export. 

But it won’t be all coding in this section, we dabble in some 3D modelling and generate our first simple cablenet model to serve as our test-bed structure for the next section.
