Illuminance Values Inside Building Outlines

Why are foot-candle/lux values displayed inside the outlines of my buildings?

If the outline for your building is drawn using the Insert Solid: Line command, it will not be considered a closed shape and illuminance values will appear inside the building, as shown below.

Instead, draw the boundary using either the Insert Solid: Rectangle or Insert Solid: Shape command.

If Starting Elevation is set to 0, foot-candle levels will not appear inside the building, as shown below.
