PLI Control file
The PLI orientation/size control file can be used to specify how certain parts are displayed in the PLI. LPub3D comes with a standard file that has a lot of parts predefined. You can modify this file, add or remove parts or create your own file if you wish.
A typical element in the standard file is for example a 32x32 baseplate. This would be too large to display at full scale in the PLI. A smaller scale is specified in the PLI Control file.
Some other examples are the bricks with studs on sides or on one side. Without the use of a PLI control file, these parts look the same at the default angle.
