I have a USD subscription, but it hasn't expired yet.

These instructions apply to USD SUBSCRIPTIONS ONLY.  

If you have just purchased your USD subscription and are within the 14-day cooling off period, you can request a refund from Trimble SketchUp US  and then make your purchase via SketchUp Australia.  

If it has passed the 14-day cooling off period, then follow these steps to disable your auto-renewal for your USD subscription.

You can continue to use your USD subscription until it expires, then you can purchase your new subscription from us i.e. BuildingPoint / SketchUp Australia.
