Dimension manager (for IESNA files)The Dimension manager is used to determine the shape and size of the luminous surface. The IESNA LM-63 and Eulumdat file formats support different luminous shape formats that are not compatible with each other.
You can select the luminous shape from the drop-down menu. If you change the luminous shape, the image will change automatically for easier identification.
You can change the size of the luminous surface by changing the width, length and height values.
You can specify the unit of the luminous surface using the selection buttons.
You can apply the changes by clicking the save button.
