SketchUp Pro now requires a subscription with every new 2013 license and for existing users upgrading simply means purchasing a subscription. There is no longer a Sketchup upgrade product. Subscriptions are available for either 12 or 24 months; users will receive technical support and future updates as and when new software is released. This also means that all users with a subscription will automatically receive SketchUp Pro 2014 when it is released in Autumn.
Upgrades are now available at CAD Software Direct.
Simply follow the steps below to upgrade:
1. Select Subscription (for existing license holders only)
2. Select your subscription length (12 months / 24 months)
3. Select your operating system ( Windows / Mac OS X )
4. Forward existing license details to firstname.lastname@example.org or just reply to your confirmation email.
