In previous versions of SketchUp, you could manage extensions in the Preferences window. By managing, I mean enabling and disabling, or uninstalling.
In SketchUp 2017, this is now done in the Extension Manager – I really like this improvement. Access it with this icon:
All of your installed extensions, new and old, are listed here. To adjust your extension security settings, click the Gear icon.
There are three settings from which to choose. The most strict is the first – SketchUp will load only identified extensions. This means extensions whose developer is on SketchUp’s A-list, and added the secret-handshake code that marks it as kosher.
The second setting lets you load unidentified extensions as well, so you can load scripts that might be a bit old, or one that your buddy wrote. You’ll have to approve each time you open SketchUp, but your answers will be remembered each time.
The last setting, Unrestricted, is the Wild West. SketchUp will load anything from anyone. Use this at your own risk.
Take a look at the notes listed for each of your extensions. “Signed” is great – approved and updated. “Outdated signature” means the extension was approved for previous versions but might not work in 2017. All of mine in this category still seem to work fine. “Unsigned” means the extension doesn’t have that secret approval code, but in my case those work fine as well.
As in all previous versions, having too many extensions enabled can slow down SketchUp, especially upon startup. So the Extension Manager makes it easy to disable – anything disabled won’t be loaded, but can be enabled later.
The “Manage” tab is where you can update anything that’s ready to be updated. I only have one so far – AMS Library. Anything that can be updated has a red “Update” button. More of these buttons will turn red as new versions of these extensions become available.
Finally, the “Install Extension” button at the lower left corner is how you bring in extensions that don’t have automatic installation. These can be from sites like Smustard. In the next post, I’ll show how to use this to install the Extension Store from SketchUcation.
