Dear gdscia,
I can help you to design requested equipment as a licensed architect with 25+ years building design and 20+ years (last 8+ on revit BIM) 3d model based 2d project delivery and BIM object development experiences. Please find building project samples in my portfolio about relevant skills and reviews about provided quality and speed!
Kind regards,
Zsolt (fabuladmin)
P.S.:
My favorite sw is adsk revit since 8+ years. Revit is a BIM sw and has API to develop interacting with microprocessor driven environment.
Regards,
Zsolt
