Convert 3D model to parametric model for cnc

I am seeking a skilled freelancer to convert a 3D model of a chair, currently in .rfa format, into a parametric model suitable for CNC machining. The goal is to create layered forms of the chair that can be exported as a DXF file for cutting. Please refer to the attached images for additional context regarding the design requirements. There are a few intricate details that will be discussed further in a conversation. Your expertise in 3D modeling and CNC compatibility will be essential for this project.
