On start-up, Karamba3D sets its default appearance and behavior according to the values listed in the "karamba.ini"-file. This file is located in the Karamba3D installation folder (double-click on the Karamba3D desktop icon to get there) and can be opened and manipulated with any text editor. The file starts with a description of the syntax rules for defining the default settings. Each paragraph that follows contains a description regarding meaning and effect of a specific property and its default value. Among other things these settings can be changed:
System of physical units ("SI" or "Imperial")
Limit distance for snapping together neighboring nodes
The value of the acceleration of gravity
Limit inclination for verticality
Number format and display properties of output values
Properties of the default materials
In case you want to keep your changes when upgrading from one version of Karamba3D to the next rename the initialization-file to "karamba_user.ini". This however incurs the risk, that newly introduced properties are missing. In such a case hard-wired default values take their place.
