The assignments of this course is to develop the entire building model using Sketch Up. I really look forward to your performance. The video in each module are designed to be finished within an hour. After watching the videos, there will a 3D modeling assignments, and a multiple-choice-question quiz. These exercise are designed to be completed around two to three hours.
