CalcuLux Software for Lighting Design – Part Two

In the previous article “ Calculux Software for Lighting Design – Part One “, I explained the main window of Calculux Indoor Software and its dropdown menus in the menu bar.

Today I will explain steps of lighting design calculations by using Calculux Indoor Software as follows.

First Step: Checking the default settings of Calculux

You should know the following facts:

  • Before you start 'your first Project’ after installation of Calculux software, you should check the default settings of Calculux. 
  • By means of default settings you can specify parameters that affect all future projects (new defined luminaires, luminaire arrangements, calculations and/or reports, etc.). 
  • The default settings remain valid the next time Calculux is started and can be changed at any time. 
  • If you specify/set the most common used parameters, you eliminate the need to specify/set the same parameters every time you create a new project. 
  • The default settings can be entered by means of the Option menu and are saved in the configuration file of Calculux. 
  • Do not use the Option menu when you want use different parameters for one particular project only. 

Default Settings to Be Checked:

For 'First Project' you are going to check the following default settings:

  1. Environment (in options menu) (default settings concerning the program environment),
