Library maintainer rules & guidelines

M2.1 3D models must be supplied in both 'step' and 'wrl' formats

Any 3D model contribution to the KiCad library must be made in both step and wrl format.


  • WRL files contain material properties and are used for realistic rendering. However they cannot be exported to MCAD packages.


  • STEP files are used for integration with MCAD software packages. These files do not contain material properties and cannot be used for realistic rendering.
