If you've been creating 3D models in Sketchup, you may be wondering how to save and share them so others can view them in 3D. Here's a simple guide to help you do just that.

Step 1: Once you've finished creating your 3D model in Sketchup, go to the 'File' menu and select 'Save As.'

Step 2: In the 'Save As' dialog box, choose a location on your computer where you want to save the file. Then, in the 'Format' dropdown menu, select 'Collada File (*.dae)'.

Step 3: Click 'Save' to save the file to your chosen location. This will create a .dae file of your 3D model that can be viewed in 3D.

Step 4: Now you'll need to convert the .dae file to a format that can be easily viewed in 3D on the web. To do this, you can use online conversion tools such as Sketchup to WebGL, which will allow you to convert your .dae file to a format that can be viewed in 3D in a web browser.

Step 5: Once you've converted the file, you'll have a link that you can share with others so they can view your 3D model in their web browser.

By following these simple steps, you can easily save and share your Sketchup models so others can view them in 3D. Whether you want to showcase your designs to clients or share your creations with the world, this method allows you to easily share your 3D models with others.
