Design comparsion

9.13 Design comparsion

1) 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;

2) Continue with the above steps to obtain design 3, 4, etc.

3) 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. As shown in the following figure:
