Creation via Boolean Operations

You can create new structures in a structure set by using Boolean operations based on existing structures. First, you specify the new structure’s name, type, and color; then, you can do any of the following operations:

  • Clone existing structure. This copies the contour points to the new structure, which you can then start manually editing, if desired.
  • Add two structures together. This merges the volumes of two existing structures to form a new one.
  • Subtract one structure from another structure. Specify two structures — one as the base and another to subtract from that — to create a new one.
  • Create an intersection of two structures. Specify two structures and create a new one that is equal to their intersection.

These options create new structures; once you initialize them, you can edit them manually or use them as inputs into new creation operations.
