There are 6 drawing tools that you can use. Each tool has a series of parameters that you can edit.
Press Tools button on your non-drawing hand and choose one with drawing hand trigger.
Click the highlighted tool again to open the control panel.
Tip: You can peel out each tool panel from your controller. Grab a panel handlebar* on the bottom and pull it off onto your scene. You can also scale the user interface. Grab and delete the floating user interface to close and place it back in your hand.
