8.1.2 Placing Calculation Zones on Existing Solid Objects

The buttons for the various types of Calculation Zones can be found in the Calculations panel Subdivision of the Ribbonbar menu system that group related commands using vertical dividers. on the Home tab A user interface object found in the Ribbonbar or Sidebar comprised of graphic and text buttons grouped based on function. or the Calculation Zone panel Subdivision of the Ribbonbar menu system that group related commands using vertical dividers. on the Calculations tab A user interface object found in the Ribbonbar or Sidebar comprised of graphic and text buttons grouped based on function. of the Ribbonbar.

The Home tab A user interface object found in the Ribbonbar or Sidebar comprised of graphic and text buttons grouped based on function. buttons are dual function; the upper portion executes the command, the lower portion initiates a drop-down menu A menu option revealed by left-clicking the mouse on an arrow shown on certain toolbar buttons. In Visual, the arrow is usually at the bottom of the button..

Once a selection has been made other than the default, the upper button portion will change to execute that command with the next press and the graphic is changed accordingly. Selecting one of the other commands from the drop-down menu A menu option revealed by left-clicking the mouse on an arrow shown on certain toolbar buttons.

Calculation Zones.

See Calculation Zone Parameters for information on specific parameters.

To place a Calculation Zone on a Surface, select the desired Surface to use as the basis by left-clicking, specify parameters as necessary in the Properties tab A user interface object found in the Ribbonbar or Sidebar comprised of graphic and text buttons grouped based on function., and press Enter or right-click to end the command. The selection of a Surface provides the bounding polygonal See Polygon. (or rectangular) shape just as if that shape had been provided while executing the commands as described in Rectangular and Polygonal Calculation Zones.

Note that the Height is applied from the Surface itself not the Cartesian Referring to positive or negative numerical values used to define position in three-dimensional space based on the three orthogonal axes (X, Y, and Z) and an origin (0,0,0). Synonymous in Visual with "cardinal". coordinate Location information usually provided in terms of (X,Y) or (X,Y,Z) components along Cartesian axes. system.

The normal of the Calculation Zone (and therefore the virtual light meter) will be pointed to the interior when placed on Room Surfaces and pointed to the exterior when placed on Structure Surfaces.

For the same reasons, Calculation Zones placed on Room Surfaces will be offset to the interior of the Room. Calculation Zones placed on Structure Surfaces will be offset to the exterior of the Structure. This of course assumes a non-zero Height is specified.
