Using the Pen
Accessing the Pen
You can access the Pen Tool by selecting Tools from the Main Menu on the right-hand-side of the screen.
By default, the 2D Pen is selected. This tool allows you to draw on the screen in front of the model. This 2D drawing will stay in place when the tool is deselected, allowing you to navigate the model behind it.
Toggle 2D and 3D
To swap between the 2D and 3D pens, use the toggle in the bottom left corner.
Choose 3D Pen to draw directly on the model in 3D. Start drawing on the model by dragging across a structure. To rotate or zoom into the model, simply deselect the Pen tool and navigate the model as normal.
Change the pen’s styling using the options available by tapping the button at the centre of the bottom of the screen.
Use Pen Size to choose the size of the pen’s stroke from a scale of 1 to 4.
Select a color from the array available. Your selected color appears in the centre of the Options button.
Drag the slider to change the opacity of the Pen stroke.
Rotating the Model
To rotate or zoom into the model, tap Done in the top right corner and navigate the model as normal.
Undo and Redo
Undo and redo drawings using the buttons at the top of the tool selection panel.
Clear only 2D or 3D drawings using the button at the left of the Tools bar when the Pen is selected, or clear all Tools using the ‘Clear’ button in the top left of the screen.
