Model alignment and scaling

The 3D models must be aligned and scaled appropriately to match the associated footprint.

Alignment

The 3D model must be aligned such that it does not require an additional alignment offset in the footprint options. When associating a 3D model with a footprint, the offset parameter must read (0, 0, 0)

Scaling

  1. STEP files include absolute dimensional information, and should never have a secondary scaling factor applied. The model scaling parameter in KiCad must read (1, 1, 1)

  2. WRL files do not specify absolute dimensions. KiCad normalizes model parameters to units of inches and the internal units (dimensionless) of the WRL model must be scaled accordingly.

Rotation

The model should be rotated such that no additional rotation is required within KiCad to align the 3D model with the footprint.
