MASTER MODELING

AN INTRODUCTION

PHILOSOPHY

"MASTER MODELING" IS A SET OF TECHNIQUES THAT LET YOU DESIGN INTERFACES BETWEEN PARTS EXPLICITLY, RATHER THAN IMPLICITLY.

IT IS ALSO SOMETIMES CALLED "TOP-DOWN DESIGN"

Example

PIN IN A HOLE

D  = 1.1mm

D  = 1.0mm

Δ   = 0.1mm

Explicit

Implicit

BUT THIS IS WHAT WE REALLY CARE ABOUT!

BOTTOM-UP

HOLE.PRT

PIN.PRT

D  = 1.1mm

D  = 1.0mm

Δ   = 0.1mm

Explicit

Implicit

BUT THIS IS WHAT WE REALLY CARE ABOUT!
