Why sdf file's rotor geometry and airframe configuragtion file's rotor geometry are different?

[dogcontrol]

Hi, I’m trying to make my custom model and i was about to apply my model’s rotor geometry at SDF file and airframe configuration file. But I found that SDF file’s rotor Geometry and airframe configuration file’s are not same. Does anyone knows Why those are different and any suggestion to select custom model’s rotor geometry?

These are tiltrotor rotor_0 geometries of sdf file and airframe configuration file at v1.13.3
