As soon as you invoke the command of the program CTRAY, you will be prompted with the scale dialog with two options, Imperial & Metric. With Metric you have two scales that you can choose between, based on your drawing's scale/units. Don't worry if you do not go with the right scale at the start-up of the program as you have the ability to switch between scales which are already available in the main dialog with the button Scale.

The main dialog of the program opens as soon as you have chosen the scale that you would like to go with. Then you can see the screenshots of this program below for clarification about the abilities and dialogs that are included in this program.
