The draw tool allows you to freely draw in CellexalVR's environment. This can be useful for multi-user sessions when you want to highlight a part of your data for other users, or if you just want to make notes for yourself. Note that anything drawn with the draw tool is not saved or logged automatically by CellexalVR, the tool is meant for ephemeral notes and sketches.
The Draw tool is found among the other tools on the Tool side of the menu. Clicking on the "Draw tool" button will open up a new menu, the draw tool menu. Clicking on the Draw tool button on the menu will activate the draw tool. There are two colour wheels, one to select a drawing colour and one to select a colour to clear. There are also buttons for clearing all drawn lines and clearing the previously drawn line.
