3-D models are used for a wide array of purposes, from entertainment to construction. While many of these models are produced using CAD programs costing thousands of dollars, you can produce very effective models using the freeware Google SketchUp application. SketchUp has many features to make the process of creating your model simple, although it does not have everything a full-featured program might include. For example, there is no direct way to produce a mirror copy of an object in a scene. However, there is a way around this.
Open Google SketchUp. Select "File" from the menu and choose "Open." In the dialog that pops up, locate a file with a model you would like to mirror and open it.
Choose the "Select" tool from the toolbar and triple-click on the model in the scene to select it. Select "Edit" from the menu and choose "Copy" and then "Paste." Place the floating copy next to the original.
Right-click on the copy and choose "Flip." From the options, choose the direction that corresponds with where you placed the copy. For example, if you placed the copy along the red axis from the original, then choose the "Red Axis." Save your work.
