2.4 User Settings
User setting allow customization of various aspects of Karamba3D:

Number format and display properties of output values.
Properties of the default materials.
Colors used for displaying rendered calculation results.
...
User settings in Karamba3D are primarily managed through text files named "karamba.ini". These files contain comments, indicated by "#", and variable assignments (see Fig. 2.4.1). Assigning "auto" or "default" to a variable will apply the default values.
The shortcut for editing "karamba.ini" user settings is via the Karamba3D menu: Settings > Edit User Settings.
To ensure a flexible and transparent user preference system, Karamba3D employs a multi-step approach for reading settings data, with each step potentially overriding the settings from the previous one:
Default Values: Lowest priority, hard-coded within Karamba3D.
Installation Folder "karamba.ini": The "karamba.ini" file located in Karamba3D's installation directory.
Installation Folder "karamba_user.ini": If present, the "karamba_user.ini" file in the installation folder is read next.
User Directory "karamba.ini": The "karamba.ini" file located in "%appdata%\Karamba" follows.
Grasshopper Document Units: The unit system (either "SI" or "Imperial") is stored directly in the Grasshopper document.
When first saving a new definition unit system and length unit are set according to the user preferences in the "karamba.ini"-files. By default this is "auto" for the unit length and either "SI" or "Imperial" for the units system. Choices set via the Karamba3D menu "Settings"-option overrides these values.
