Adding A Grid Of Calculation Points
This command allows you to create a grid of points for which illuminance values will be calculated. Grids may be specified in Plan or Elevation view. 2-point grids are orthogonal and may be tilted along their baseline. 3-point grids are specified by locating the endpoints of the baseline, then specifying the top right corner of the grid. Like 2-point grids, they may be tilted about their baseline as well.
To measure Exitance or Luminance, use the Automatic Placement command to select the surfaces (object or room) for which Exitance or Luminance calculations are desired.
