### Rotate a Component
|
||||
The rotation of components in KiCad Footprints does not always match the orientation in the JLC library.
|
||||
Add an 'JLC Rotation Offset' field with an counter-clockwise orientation offset in degrees to correct this.
|
||||
The rotation of components in KiCad Footprints does not always match the orientation in the JLC library because KiCad and JLCPB used different variation of the same standard. Most of the rotations may be corrected by the `rotations.cf` definitions. To the exception cases: add an 'JLC Rotation Offset' field with an counter-clockwise orientation offset in degrees to correct this.
