Custom luminaire layouts may be saved as user defined arrangements in PTB to be used repeatedly with any photometric file. Whether one chooses to save an existing arrangement with modifications, or create one from scratch, either can be saved independently quickly and easily.
User defined arrangements are appended with the prefix "User_" and saved with an ARR extension.
When a custom arrangement is used in PTB, none of the default positioning metrics are applied (i.e., MH, Arm Length and Offset) to prevent overwriting the X, Y and Z coordinates used the arrangement.
Note: You may use these arrangements in AGi32 by copying them into the appropriate Arrangements folder.
