Editing Rooms - Concepts
Rooms placed in AGi32 can be edited at any time after they are created. Only one room may be selected during any single Edit session. However, if you are interested in modifying the room surface properties (such as color/reflectance, texture, etc.), the Surface Edit command allows you to select multiple rooms at once.
Each individual room type has both common and unique properties. Selecting a room with the Edit Room command will open a dialog specific to that room type.
All room properties displayed in the dialog may be modified. Non-geometric or surface modifications can be made without having to recalculate - Labeling, Description and Wireframe color. Surface modifications will require recalculation. Geometric modifications will also require recalculation and may require recreation, depending on the modification applied. For example, if you change the Dome Height on a Round-Dome Room, the room needs to be recreated. When a room is recreated, its surface attributes default to their original parameters. Most importantly, flipped surfaces (surfaces whose normals were modified to face the opposite direction from their original specification) will be lost when the room is recreated. In these cases, simply flip the surfaces back with the Surface Edit command.
The Edit dialogs allow you to change the Geometric and General properties directly. A 3D preview of all room surfaces is shown in the dialog. To edit any of the surface attributes, click the Surface Edit button to show the Surface Edit dialog.
Curved Surfaces
AGi32 approximates curved surfaces with a series of rectangular planar objects (flat objects). The parameter specifying the angular increment used is Initial Curve Increment specified in the Advanced System Settings dialog. Increasing or decreasing this value will not affect current rooms. You must recreate the room with the appropriate Add-Room command to change the number of panels in the room arcs or domes.
Note: AGi32 automatically smooths adjacent surfaces composing a dome or arc, for presentation purposes in Render mode. If all that is desired is a smoother appearance, AGi32 provides that automatically. However, if you require more surfaces for calculation or geometric modeling purposes, then the Initial Curve Increment modification is necessary.
