3Ds Max - Modelling a building

Using 3Ds max we were shown how to model a building using splines, extrude modifier and editable polygons.

here i started off mapping out the building walls by using create - line tool and using snap to grid points. 

 The next step was to use the extrude modifier to get the walls to rise.

I then create lines that intersected each wall of the building and joined the gaps with the bridge tool to make the doors. I then created a quick slice through one wall on the front port and used 'extrude' to push back the window and i then deleted the polygon, creating a window.

 This is the final rendering of the building.
