Volume boolean operations

Menu: Geometry->Edit->Volume boolean op.

The GiD Volume Boolean Modeler has been designed to accomplish geometric feats such as physically punching a hole through a volume, combining several volumes into one, and creating a new volume from the intersecting part of several separate volumes.

The valid volume boolean operations are:

• Union: Fuses several volumes wherever they intersect to create a single, more complex volume.
• Intersection: Creates a volume based on the intersecting points of several separate volumes.
• Subtraction: Negates a specific portion of a volume to create a hole or indentation.
• Subtraction and intersection: Creates the intersected and the substracted volume at the same time.

Note: First the volume where to substract must be selected, then the volumes to be substracted (order is important when dealing with subtraction).
