Setting Diffuse Transmittance

Diffuse Transmission occurs when light passes through a translucent material, such as frosted glass, causing the light to scatter uniformly in all directions. When a Solid object is initially created in Visual, that object only blocks and reflects light – it doesn’t allow for light to pass through it. If you want light to pass through an object, you need to set a Diffuse Transmittance for that object. To set Diffuse Transmittance for a Solid object:

  1. Click on the Edit menu and select Properties.
  2. Left click to select the desired object.
  3. Right click to display the Properties screen.
  4. Expand the different surfaces of your solid by clicking on the + symbol next to the name of your solid.
  5. Select the desired surface.
  6. Type in the desired percentage of Diffuse Transmittance in the textbox.

How do I determine the height of an existing Calculation Zone?

In Visual, your calculation zone should be placed at the height of where your primary task will be performed. For example, if you are performing a lighting design for an office space, your calculation zone should be placed at desk height. After a calculation zone has been placed, you can verify the height of the calculation zone by doing the following:

  1. Click on the Edit menu and select Properties.
  2. Left click the desired calculation zone to select it (the calculation zone should highlight in red when selected.)
  3. Right click to bring up the Properties screen.
  4. The Z value to the right of Center Point from the Reflectance section is the calculation zone height.

The height can also be determined by looking at an elevation view and placing the mouse at the height of the calculation zone. The height of the calculation zone will be the Z coordinate value at the lower right hand corner of the screen.

How do I add Luminaire Labels?

If you’re using more than one type of luminaire, you may want to add luminaire labels to your design. Visual automatically generates a luminaire label each time a phtometric file is added to the Luminaire Schedule. You can either use the default labeling scheme that Visual creates or you can use your own. In order for labels to be included in your final drawings, you need to do the following:

  1. Double-click on the illustration to display the Illustration Editor.

  2. In the toolbar, click the button with the luminaire icon with the letter A next to it to add the labels. Similarly, click the button with the luminare with the number 1 next to it to have Visual count the number of each type of luminaire in your design (Note: Luminaire labels only appear in the Print Editor. They will not appear in the design environment.)
