TWO APPROACHES TO DESIGN
1. BOTTOM UP DESIGN
2. TOP DOWN DESIGN

BOTTOM-UP DESIGNHave the definition of parts in the system that we design
Assemble every parts together to build the final assembly
Create drawings for each components ,subassembly and final assembly

PROECESS OF BOTTOM-UP DESIGN IN Creo
Individual components assembled together to create a final assembly
AIR VALVE

PROECESS OF BOTTOM-UP DESIGN IN CreoDrawings is referred to the Component.
Hence a change in the Component reflects the drawing automatically
Also a component definition change in the drawing reflects the part too.

PROECESS OF BOTTOM-UP DESIGN IN CreoDrawings is referred to the Assembly.
Hence a change in the Assembly reflects the drawing automatically

PROECESS OF TOP-DOWN DESIGN IN Creo
Design objective here is to make a cabinet (enclosure) for the printed circuit board.
The inputs shall be a dummy PCB board design and other design parameters (For E.g.. the heat generated per hour etc.)
![Page 8: PTC® Creo® Parametric ™ AN INTRODUCTION AND BASIC TRAINING ON PTC® Creo® Parametric™](https://reader033.vdocuments.mx/reader033/viewer/2022061616/56649d355503460f94a0c077/html5/thumbnails/8.jpg)
PROECESS OF TOP-DOWN DESIGN IN Creo
Here we have the design input, the PCBShown the overall length X width. Height is not shown here which is important too.

PROECESS OF TOP-DOWN DESIGN IN Creo
Shows the Top-Down approach in designing a cabinet from the inputs given.

TESTING THE DESIGN
Create a virtual loading environment to test your design in Creo Simulate
![Page 13: PTC® Creo® Parametric ™ AN INTRODUCTION AND BASIC TRAINING ON PTC® Creo® Parametric™](https://reader033.vdocuments.mx/reader033/viewer/2022061616/56649d355503460f94a0c077/html5/thumbnails/13.jpg)
TESTING THE DESIGN
Conducting FEA on your design to find the flaws
![Page 14: PTC® Creo® Parametric ™ AN INTRODUCTION AND BASIC TRAINING ON PTC® Creo® Parametric™](https://reader033.vdocuments.mx/reader033/viewer/2022061616/56649d355503460f94a0c077/html5/thumbnails/14.jpg)
TESTING THE DESIGN
Make design modifications. Re-run the FEA and make sure that the design successfully handles the loads. Check for the stress values and deflections.

FINAL DESIGN
Once the design is frozen, Documentation comes next.
