Architectural Tutorial

This chapter tests your drafting and modeling skills. To successfully complete the tutorial model, you will need to apply the lessons and procedures you learned in earlier chapters. The exercise focuses on the construction of a complex building from scratch. You will draft an intricate floor plate, generate an involved building massing, and apply a set of custom window and door components to finalize the structure. In addition, you will learn how to work with arcs and circle edges and how to graft components onto curved surfaces.
The tutorial uses the Jefferson County Courthouse building, located in Lakewood, Colorado, as its inspiration. You will create a conceptual and reasonable facsimile model of the building. The challenging nature of the building design makes it a great exercise.
This tutorial utilizes SketchUp Process Modeling. Once again, the process is as follows: 1. Draft a 2D base plan/outline of the building footprint. 2. Push/Pull the volumes.
3. Add color.
4. Construct the custom window and door components. 5. Arrange the components on the building.
Working with arcs and Circles
Arc and circle geometry is not constructed from true curves or circles. Rather, arcs and circles are composed of a series of linear edges, or facets, to depict curvature and roundness.
