2. Then open the program in SKETCHUP, select user settings in the view, and select "Unit Form" as "Decimal" mode in the "Set Basic Units" option. In the rendering options, select Show Outline to deselect it. This operation aims to ensure that the lines in the imported dwg file become thin lines for accurate modeling.

3. Import a CAD file, select the file option in the menu, select the import command, and then select the import DWG/DXF option in the submenu. After that, the system will automatically pop up a dialog box, and cad drawings will be automatically imported into sketchup.

4. Stretch the building blocks of floors A, B, C and D? Establish a model on the platform, and make full use of the rectangle command to form a plane closed figure on the plane (as long as the plane is closed, the interior of the closed part will be automatically filled with a filling color or covered with MakeFace 1. 1 plug-in), thus stretching the plane to generate an entity. [Plane A (a layer of plane) only plays the role of positioning measurement of modeling dimensions.

5. Paste the material: Open the "Material" in the "Window". If we need to apply the material to the model, then we will import the picture of the material into our sketchup material library.

6. In the pop-up "Add Material Blend" dialog box, check the "Use Map" option.

7. Then the system will automatically pop up a "Select Image" dialog box.

8. Then, after finding the picture of the material you want to apply, click "Open" and select the "Add" command in the folder that pops up automatically. At this point, close this dialog box, in the material, in the model, and it is finished.
