sensor casing

Its a old(10 yrs) design of our company's client. Now its not in production which allows me to share it public. New design is so complicated(100 dimension minimum).but i cant share it here, cause its so confidential. basically, my job is to convert every incoming 2d drawing into 3d. After this, process plan is prepared. Then estimation done for quotation. if this quotation got approved by our client, then i have to give G-codes for VMC and LATHE. if job done by manual machines, then i have give step by step process diagram for each setting and machine. Also i do fixtures and jigs design if required.
