Procedures
To set units correctly:
Follow these steps if your scene does not already use real-world units.
1 Right-click 3D Snap Toggle and on the Snaps panel, clear all the
settings. Then turn on Vertex to set vertex snap. Close the dialog.
2 Choose Tools > Measure Distance to measure some object in the scene
for which you know the size; for example, a door or window. The distance
displays in the Coordinate Display of the status bar.
3 Choose Customize > Units Setup and adjust the Scene Unit Scale.
For example, if your object measures 35 scene units long, and your model
uses US Standard measurement, then you would enter 1 for the scale,
and choose Inches from the drop-down list. This would give you an object
35 inches long.
If your object measures 90 scene units long, and your model uses Metric
measurement, then you would enter 1 for the scale, and select Centimeters
from the drop-down list. This would give you an object 90 centimeters
long.
Example: To process radiosity with photometric lighting:
1 Use a scene that has geometry set to the correct scale. For more
information, see
To set units correctly on page ? .
For example, if the ceiling is 96 scene units high in the model, make sure
the units are set to US Standard (inches) and not Metric.
2 On the Create panel, click Lights.
3 Choose Create > Photometric Lights > Target Point Light.
4 Choose Photometric from the drop-down list. (The default is Standard.)
5 In the Object Type rollout, click Target Point.
6 Drag in a viewport. The initial point of the drag is the location of the
light, and the point where you release the mouse is the location of the
target.
The light is now part of the scene.
