Modifying Solids

This section teaches you how to modify solids that are inserted on your drawing. You will move, copy, delete, and change the elevation of a solid.

Inserting a Solid​

  1. Run the Insert Solid: Shape command. The Insert Solid: Shape dialog box will open.
    Ribbon: DM Photometrics→Solids→  Insert Solid: Shape
    Pulldown Menu: DM Photometrics→Insert Solid: Shape

  2. Make sure Starting Elevation is set to 0, Ending Elevation is set to 20, and Reflectance is set to 0.5.

  3. Press the button. You will be prompted to specify the boundary of the solid.

  4. Insert the boundary surrounding the middle tree at the top of the site as shown below. Approximate the circle by drawing a polygon around it.

  1. Run the Calculate command to see the changes in the illuminance levels. Leave the settings as they are and press the button.
    Ribbon: DM Photometrics→Calculate→  Calculate
    Pulldown Menu: DM Photometrics→Calculate

Copying a Solid​

Use the standard CAD COPY command to copy the solid to cover the tree to the right.

Moving a Solid​

Use the standard CAD MOVE command to move the solid on the left to cover the tree to the left.

Deleting a Solid​

Use the standard CAD ERASE command to delete the solid on the right that is closest to the light fixture.

Changing Settings on a Solid​

  1. Run the Query command.
    Ribbon: DM Photometrics→Query→  Query
    Pulldown Menu: DM Photometrics→Query

  2. Select the solid. The Query Solid dialog box will open. It will display the current settings for the selected solid.

  3. Change Ending Elevation to 5.

  1. Press the button. The drawing will not change, but the elevation associated with the solid will be updated.

  2. Run the Calculate command to see the changes in the illuminance levels. Leave the settings as they are and press the button.
