Add a new python file by clicking on the plus sign named `000.pattern.py`. Then copy-paste the code below that extracts the mesh pattern from the session file.

 The session file employs the compas.scene data structure for storing: Pattern, FormDiagram, ThrustDiagram, and ForceDiagram. It also stores general settings for drawing and thrust-network analysis. We will use two attributes: Pattern and ThrustDiagram for mesh transformation into solid blocks. The scene also helps to visualize COMPAS items (geometry & data structures).
