Understanding the Design process behind Spider webbed wheel Rims

front wheel cad model= https://drive.google.com/open?id=1BTjtbL1HU_N7H5_oQqkWb1a0vdEPlfQj

THE MODEL IS COMPOSITION OF DIFFRENT PARTS . THE PARTS ARE AS FOLLOWS:-

- RIM OF WHEEL

-BRAKE ROTOR

- CALLIPER

- TYRE (ALL THE PROCESS \" HOW I MODELED WAS ILLUSTRATED WITH THE HELP OF SCREEN SHOTS . THE DIMENSSIONS CONSTRAINTS , TOOLING FEATURES, AND ADVANCES COMMAND,

BY MODELING THIS FILE I GOT DEEP UNDERSTANDING OF THE USE OF VARIOUS SKETCHING TOOLS SUCH AS(CONVERTING ENTITIES, OFFSETTING ENTITIES ETC....

THE EXPLANATIONS IS ILLUSTRATED BELOW IN A PREDEFINED SEQUENCE:-

********************** RIM OF WHEEL***************************

1. BY SKETCHING ON THE RIGHT PLANE AND USING REVOLVE COMMAND I CREATED TWO ROUGH BODY REFERANCES , ALSO THERE IS A NEED FOR THE FURTHER ADDING AND REMOVAL OF MATERIALS.

2. THEN I CREATED SPOKES BY USING A CONSTRAINTS DRAWN SKETCH AND THE BOSS EXTRUDING (FOR EX TRUDE COMMAND I DESLECT MERGE OPTION.

3. THEN I REMOVED THE CURVED SHAPED MATERIAL BY EXTRUDE CUT ON THE CENTER PLANE BY TAKING THE REFERANCE GEOMETRY AS ROUGHLY EXTRUDED SPOKE ELEMENTS.

4. AFTER THAT I DRAWN A RIBS GEOMETRY TO CONNECT THE EXTRUDED SPOKES OF RIM .

5. AFTER THAT FULLY GEOMETRY FOR THE SPOKES AND THE OUTER PERIPHERY WAS READY SO I USED CIRCULAR PATTERN > EQUALLY SPACED> 3 NOS. > BY TAKING THE REFERANCE GEOMETRY AS SPOKE ELEMENTS.

6. THEN BY GOING TO COMBINE FEATURE , I ADDED THE OUTER CIRCUMFERANCE AND SPOKES AND THE CENTER HUB . AS SINGLE BODY ELEMENT.***

*****************************************BRAKE / ROTOR************ BRAKE CALLIPER *********************************

1.BY TAKING THE FRONT FACE OF HUB AS AREFERANCE SKETCH PLANE I SKETCHED THE ROTOR DIMENSSION AND OFFSETTED THE EXTRUDE AWAY FRON THE HUB,

2.THEN I DRAWN A 8MM CIRCLE ON THE FRONT FACE / FLAT FACE OF THE EXTRUDED GEOMETRY, AND LINEAR PATTEN THAT HOLE AT >MOS3 > AND ANGLED DIMENSSION OF 142 DEGREE.

3.THEN USING CIRCULAR PATTERN I CRETED MULTIPLE COPIES OF THAT EXTUDED HOLE ON THE FLAT FACE .

4.THEN FOR CALLIPER I CRETED A CONTRAINED SKETCH ON THE PERVIOUS FACE , AND EXTRUDED THAT. BY MERGING WITH THE ROTOR GEOMETRY, AND GIVING BOTH FULLY DEFINED DIRECTIONS.

5.AFTER THAT CHAMFER WAS GIVEN >AS DISTANCE DISTANCE > BOTH DIRECTION (8MM, 20MM).> BY TAKING REFERANCE AS TOP FLAT FACE OF CALLIPER.

6. FILLET OF 4MM IS PROVIDED ON THE SHARE EDGING AS SHOWN.

**************************************TYRE OF WHEEL ************************************

1.USING CONVERT ETITIES OPTION TAKE A REFERENCE OF RIM CURVE AND SKETCHING THE GEOMETRY OF TYRE ON FRONT WHEEL .

2.BY CREATING THAT SKETCH MAKE REVOLVE OPTION TO CREATE OUTER PEREPHERY, THEN I CREATED THE TYRE TREADS...

3. THE TREADS ARE CREATED ON THE FRONT PLANE BY SKETCHING 4 RECTANGLES ON THE FRONT PLANE AND PROVIDING THEM THE SUITABLE RELATION AND ALSO THE PRISCRIBED DIMMENSSIONS ALONG WITH ORIGIN AND CONVERT ENTITY REFERANCE LINE.

4. THEN USING OFFSET EXTRUDE CUT 4MM OF MATERIAL FROM THE TYRE SURFACE .

5. AFTER TAHT USE CIRCULAR PATTERN AND PATTERN THE TREADS AS IN THE IMAGE.

IN THIS WAY I CREATED FRONT WHEEL ..
