Summary of issue An issue was discovered with SketchUp 2016 where uninstalling the program resets your default Internet browser. This issue only affected computers using Microsoft Windows that had SketchUp 2016 installed and then uninstalled. Description
When you install plugins, or "Ruby scripts," or "extensions," on your computer, you may notice that the tool doesn't appear in the 'Plugins' menu. Please note that the author of the plug-in must explicitly choose to put it in this menu. The plug-in may reside in a different menu, such as 'Tools' or 'Draw.' Sometimes, you will only see the plug-in in a context menu - the menu that appears when you right-click on something. Be sure to read any documentation related to the plug-in to fully understand its use.
If you are getting an error that says "This application has been authorized" when attempting to log into any of the SketchUp websites (forums, 3DWarehouse, Extension Warehouse), most likely the solution is to change your internet browser's security settings to allow cookies from 3rd party websites.
This error message can occur if your computer appears to be on the network more than once (in other words, it appears on the network under multiple IP addresses). The most common cause of this is that your computer has both a wired and wireless local area connection. It's easy to check whether this is the case and, if it is, to correct it:
This message will appear when the total instances of SketchUp Pro running is more than the total number of seats available for the license. Let's say, for example, you have a three-seat network license and three instances of SketchUp Pro are running. This message will appear when someone tries to launch a fourth instance of SketchUp Pro. To purchase additional network seats please visit our online store.
Situation: you are using a network version of SketchUp Pro on a PC, and when you start it, this message is displayed: The server.dat specifies a SketchUp license file that does not exist or is not currently accessible: \\ServerName\ServerFolder\SketchUp#.lf. This message can be displayed for two reasons. To figure out which reason applies, try to browse to the license folder and view the SketchUp#.lf file:
Clipped or Missing Faces If you orbit around your model and you see an effect that looks like a section plane attached to your view at a fixed distance you may be worried that something is wrong with your model. Worse yet, objects may disappear or appear to shake when you try to zoom in.
This is a known issue with some OpenGL graphics drivers. We have built a workaround option into SketchUp: In SketchUp, open the "Window" menu. Click "Preferences." Click "OpenGL." In the "Acceleration" section, select the "Correct reversed picking driver bug" option. Click "OK."
To keep SketchUp interactive and responsive while you're modeling, SketchUp waits to render the model with full detail until you temporarily stop working on the model. For large models that are using a complex Style, you may notice a significant pause when you end a modeling operation before the full-detail rendering completes. This pause allows you to start your next modeling operation without the renderer interrupting your work.
If your Logitech mouse is running fine in other programs, but very slowly in SketchUp, there is a setting you can switch to eliminate this problem. The newer Logitech mouse drivers have a special setting for use with games that disables acceleration, but this actually applies to all applications that use OpenGL, which includes SketchUp. To re-enable acceleration: Open the "Properties" dialog box for your Logitech mouse driver. Click the "Motion" tab. Clear the "Disable acceleration in games" check box.
