If the room permissions allow it, drawing mode lets you draw on almost all surfaces and objects in a room.
To enable drawing mode, click the Drawing Mode button in the toolbar:
When enabled, you can draw on things.
Here are some shortcuts that change the way Drawing Mode works:
|SHIFT+Mousewheel||Change drawing size|
|CMD+Z / CTRL+Z||Undo|
|Right click||Exit drawing mode|
To make your drawing into an object, hold SPACE, hover the mouse over your drawing and click the "Create" button. This will turn your object into a 3D model.
