Arch Space

Description
Basically it is a solid shape (but represented as "empty") that can be defined either
 * 1) by an underlying solid shape object or
 * 2) by a set of boundary faces from other objects. In that case, the space volume is defined by taking the bounding box of all the faces, then removing exterior parts behind the boundary faces.

New boundary faces can be added later with the Arch Add button, even to spaces created from a solid. Existing boundaries can be removed with the Arch Remove button.

Finally, the space uses the new "detailed" display mode (that will in the future be used by all Arch objects) to show the area, taken from a horizontal section plane that cuts the space at its center.



How to use

 * Select faces or objects
 * Press the button, or press,  keys

Limitation
