To begin adding cuts, select Tools from the main menu, and select Cut from the Tools menu.
Using the Cut Tool
Start a cut by dragging a line across the section of the model you’d like to cut. When you have completed your line, you’ll be given the option to cut either side of that line.
Cut Multiple Structures
Choose to cut only one structure at a time or multiple structures using the controls in the bottom left corner of the screen. When you draw your cut lines, the structures that will be included in the cut are highlighted, so you can see a preview of the scope of your choice.
Along the bottom of the screen are the Cut Options. By default, the cut line is chosen. Two other options are available.
Draw two lines on the model, and have the section between them cut away.
Draw a circle on the model, and have its contents cut away.
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 cuts using the buttons at the top of the tool selection panel.
When using the Cut tool, tap the ‘Clear Cut’ button in the top left corner of the screen to remove all cuts. At any point, select the ‘Clear’ button in the top left corner of the screen, and select to Clear Cuts or to Clear All.
