VR Stage 2: Extrude 2D Splines

I extruded the 2D splines to create the main structure of my house in 3D. I decided to model the existing house first and then use it as a basis create the proposed instead of modelling them both twice. I did not have measurements for the height of the house and therefore used the elevations as a guideline to estimate it. I kept the 2D drawings in the scene and positioned them on the model. This was useful for the placement of the doors and windows.
