Today the Sketchup team released a new version of Sketchup, aptly titled "Sketchup 2013
The Sketchup team has added a host of new features to Sketchup. One of my favorits is the "Extension Warehouse". From right within Sketchup you can now browse, install and update extensions. A centralized plugin repository is something that I think Sketchup has needed for years and it's finally here.
In addition to the Extension Warehouse, you'll find speed improvements and hatch patterns in LayOut, a reworked toolbar interface for Windows (Customizable toolbars!!) and a whole new icon set.
In the coming weeks we'll go into more detail on these features, but for now, I suggest you go give it a download.
