Add Object Opening - Side

The ability to create an opening in the side of an object expands object use beyond applications concerning simple solids. An object can now serve as an interior space, much like a room, albeit, with opaque (2-sided walls), or, as an object that displays access to both interior and exterior surfaces.

The creation of openings utilizes Surface View mode. When you select a surface to locate an opening, AGi32 will display that surface in surface view where only entities in the same coordinate plane are visible. In the case of Object Side openings, surface view mode looks at all surfaces from the frame of reference of an observer OUTSIDE of the object.

To create an opening in an object side

1. Select the Object-Opening-Add-To Side command from the Modify menu or from the Rooms/Objects toolbar, select .
2. Select the side surface to receive the opening.
3. Draw the opening on the surface, right click to close. The opening can be any shape and can include Arcs (F4).

Using Snap when specifying openings

1. Openings must be contained within the surface. Attempting to locate a vertex outside the surface will prompt a warning.
2. The sides of an opening must not cross one another.
3. Openings can be of any shape and may include arcs (F4).
4. Openings can be created in either clockwise or counterclockwise directions.

Limitations of top openings

1. Openings cannot be edited in any way, they are fixed.
2. Openings cannot be copied or arrayed at this time.
3. Modifications in Object height will cause all Top openings to be lost.
