Thank you, tgibson. As I said I am new to Sketchup. I have some experience modeling for fs9/fsx/p3d and my intention in learn Sketchup is to have a unique 3D modeling tool and export the modeled 3d objetcs from that to others 3d formats.
- In SketchUp, select Window > Extension Manager. The Extension Manager window appears.
- Click the Install Extension button.
- In the Open dialog box that appears, navigate to the .rbz file saved to your computer, select the file, and click OK (Microsoft Windows) or Open (Mac OS X).
- When SketchUp warns you about installing only extensions from trusted sources, click Yes to proceed and install your extension. (This assumes you do, in fact, trust the source of your extension.)
