- If the users has completed the modeling of design one (1.skp) for a certain project. users can copy 1.skp and name it 2.skp, and modify it to obtain design 2.
- Continue with the above steps to obtain design 3, 4, etc.
- Open SketchUp, click the "Design comparsion" button, select the folder where the SKP file is located, and the software will output detailed comparison results of the four designs.
