With the glue tool selected (in either block or group mode) touch your wand tips together when your delete hand turns yellow hold down its trigger button and pull out a volume. With the blocks you'd like to remove deleted release your trigger. Poof! Annoying blocks gone.
Choose the glue tool from the menu, touch your pointers together, when the arrow glows yellow click and hold the trigger, drag out your hands to create a volume. When you let go any blocks inside of the volume will become a group.
With the glue tool selected highlight hold your trigger down and drag your pointer through the blocks you'd like to glue. For greater accuracy you can also glue blocks individually by highlighting a block and clicking and releasing your trigger.
The block library can be a toil to sort through, so we've added a block library so you can quickly access the blocks important to your building session. Simply drag and drop a block from the block library or scene into the inventory. You can also store parts in the inventory.
To rewind click the "start rewinding button" on the Rewind Undo menu. This will automatically start a real time rewind on your build. To skip backwards faster click the button with the arrow and line. The same things can be done to fast forward. When you're ready to start building again simply click "resume building."
