Week 10 - Challenge 2- Attachment Feature Creation (Dog House)

REPORT ON DESIGNING DOOR TRIM WITH DOG HOUSE:-

STEPS TAKEN FOR DESIGNING ARE AS FOLLOWS-

1.INPUTS:

• HERE WE WILL RECEIVE A CLASS A SURFACE AS AN INPUT TO CREATE AN FINAL 3D COMPONENT WHICH IS SHOWN IN BELOW IMAGE.

2.TOOLING AXIS CREATION FOR CLASS A:

• TO CREATE A TOOLING AXIS WE HAVE TO CHECK WHEATHER ALL THE SURFACES ARE VISIBLE OR NOT, HERE ALONG Y DIRECTION ALL THE SURFACES ARE VISIBLE.

• HERE CREATE A POINT ON THE EXTRACTED SURFACE OF CLASS A, DRAW A LINE WHICH IS AT 3 DEGREES FROM THE LINE DRAWN ON THE SURFACE WHICH IS OBTAINED BY USING A INTERSECT 3D ELEMENT TOOL WHICH IS AS SHOWN IN BELOW IMAGES.

• SIMILARLY ANOTHER LINE IS DRAWN AT AN ANGLE OF 3 DEGREE FROM THE LINE WHICH IS DRAWN ON THE SURFACE SO AS TO CLEAR IN THE DRAFT ANALYSIS WHICH IS AS SHOWN IN BELOW IMAGES.

• THEN BOTH THE LINES FROM THE SKETCH IS BISECTED TO OBTAIN A DUMMY TOOLING AXIS WHICH IS AS SHOWN IN BELOW IMAGES.

• AGAIN TO CLEAR THE DRAFT ANALYSIS ON THE CLASS A SURFACES LINES ARE DRAWN ALONG THE SURFACES AND BISECTED TO OBTAIN AN DUMMY TOOLING AXIS WHIS IS AS SHOWN IN BELOW IMAGES.

• HERE THE BISECTING LINE OF SKETCH 5 AND 6 IS AGAIN BISECTED WITH THE LINE FROM SKETCH 7 TO OBTAIN AN TOOLING AXIS WHICH IS AS SHOWN IN BELOW IMAGES.

3.DRAFT ANALYSIS ON CLASS A SURFACE:

• HERE DRAFT ANALYSIS IS DONE TO CHECK WHEATHER THE SURFACE CLEARES THE CORE OR CAVITY SIDE, SELECT THE TOOL CLICK ON COMPASS AND PLACE IT ON THE TOOLING AXIS AND LOCK IT THEN SELECT THE SURFACE AND THE RESULTS ARE SHOWN IN THE FORM OF COLOUR CODES BASED ON THIS WE CAN IDENTIFY WHEATHER THE SURFACES CLEARES OR NOT AS SHOWN BELOW.
• IN THE GIVEN CLASS A SURFACE SOME OF THE SURFACES CANNOT BE CLEARED AS THEY ARE ALMOST PARALLEL TO THE TOOLING AXIS, TO PROVIDE AN MINIMUM DRAFT WE HAVE TO MAKE CHANGES IN THE CLASS A SURFACE BY USING ALIAS SOFTWARE.

4.CLASS B SURFACE CREATION:

• HERE THE CLASS A SURFACE IS OFFSETED AT 2.5MM TO OBTAIN AN CLASS B SURFACE.
• SOME OF THE ELEMENTS OR FILLETS WILL BE MISSING AFTER OFFSET AND BY SOLVING THESE ISSUES THE CLASS B SURFACES IS CREATED .
• THE OPERATIONS USED TO CREATE THE CLASS B SURFACES ARE SHOWN IN TREE STRUCTURE.

5.FILLET VALUE DETERMINATION:

• THESE ARE CREATED TO GET AN EXACT FILLET RADIUS OF A CLASS A SURFACE.
• HERE WE HAVE TO EXTRACT THE FILLET AND THEN WE HAVE TO UNTRIM TO GET AN EXACT VALUE ARE AS SHOWN IN BELOW TREE STRUCTURE.

6.CLASS C SURFACE CREATION:

• HERE WE HAVE TO CONSIDER THE CLASS A SURFACE WHERE WE HAVE TO CREATE AN BOUNDARY, USING SWEEP COMMAND PROVIDE 3 DEGREE DRAFT ALONG THE TOOLING AXIS.
• TRIM ALL THE SWEEPS TO CREATE A SINGLE SURFACE, THE OPERATIONS USED TO CREATE CLASS C SURFACE ARE AS SHOWN IN TREE STRUCTURE.

7.CLASS A AND CLASS C JOIN:

• HERE WE HAVE TO JOIN CLASS A AND CLASS C SURFACE WHICH IS AS SHOWN IN BELOW IMAGES.

8.FINAL TRIM:

• HERE THE JOINED CLASS A AND CLASS C SURFACE IS TRIMMED WITH CLASS B SURFACE TO GET AN CLOSED SURFACE AS SHOWN IN BELOW IMAGES.

9.PART BODY(SOLID COMPONENT):

• HERE WE HAVE TO CREATE AN SOLID COMPONENT BY USING THE CLOSE SURFACE TOOL FROM THE PART WORK BENCH WHICH IS AS SHOWN IN BELOW IMAGES.

10.DOG HOUSE 1 CREATION:

• TO CREATE AN DOG HOUSE EXTRACT THE SURFACES ON WHICH IT SHOULD BE CONSTRUCTED, CREATE A POINT ON THE SURFACE THEN USING POSITIONED SKETCH DRAW THE SKETCH AS PER REQUIREMENT WHICH IS AS SHOWN IN BELOW IMAGES.

• EXTRUDE THE SKETCH TO A REQUIRED DIMENSIONS.

• A LINE IS CREATED AND EXTRUDED AT A REQUIRED DIMENSIONS AND TRIMMED TO OBTAIN THE DOG HOUSE AS SHOWN IN BELOW IMAGES.

• USING THICK SURFACE TOOL THE THICKNESS OF 2MM IS PROVIDED TO THE DOG HOUSE.

• THEN USING THE PLANE WHICH IS OFFSETED AT AN REQUIRED DISTANCE SPLIT THE THICKENED DOG HOUSE AS SHOWN IN BELOW IMAGES.

• TO CREATE A DOG HOUSE WALL THICKNESS AT THE INTERSECTION OF THE PART WALL (C) WHICH SHOULD BE 40% OR LESS THAN THE MAIN WALL THICKNESS (T) IS 1MM AS THE T-2.5MM.
• THE HEIGHT (B) SHOULD BE 3 TO 6 MM.
• HERE CREATE A OFFSET BETWEEN 3 TO 6 MM AS THE SURFACE ON WHICH THE DOG HOUSE IS CONSTRUCTED IS OF IRREGULAR SHAPE SO THE HEIGHT (B) MAY VARY ACCORDING TO THE SURFACE.
• USING MULTIPLE EXTRACT SELECT THE FACES OF THE DOG HOUSE AND OFFSET TO 1MM AND THEN TRIM IT WHICH IS AS SHOWN IN BELOW IMAGES.

• USING SPLIT TOOL IN PART WORKBENCH CREATE THE DOG HOUSE OF REQUIRED DESIGN WHICH IS AS SHOWN BELOW.

• PROVIDE A DRAFT OF 1.5 DEGREE ON THE OUTER WALLS AND 0.5 DEGREE ON THE INNER WALLS OF THE DOG HOUSE.
• NECESSARY FILLETS IS PROVIDED ALL OVER THE DOG HOUSE WHICH IS AS SHOWN IN BELOW IMAGES.

11.DOG HOUSE 2 CREATION:

• SIMILARLY DOG HOUSE 2 IS CREATED AS DOG HOUSE 1 AS SHOWN IN BELOW IMAGES.

12.DRAFT ANALYSIS FOR DOG HOUSE:

• THE DRAFT ANALYSIS FOR THE DOG HOUSE ALONG TOOLING AXIS ARE AS SHOWN IN BELOW IMAGE.

• THE DRAFT ANALYSIS FOR THE DOG HOUSE ALONG SIDE CORE AXIS ARE AS SHOWN IN BELOW IMAGE.

13.DOOR TRIM FINAL COMPONENT:

• BOTH THE DOG HOUSE 1 AND 2 ARE UNION TRIMED WITH THE DOOR TRIM FINAL COMPONENT AS SHOWN IN BELOW IMAGES.

14.DRAFT ANALYSIS ON FINAL COMPONENT:

• HERE DRAFT ANALYSIS IS DONE TO CHECK WHEATHER THE SURFACES CLEARES OR NOT AND THESE ARE INDICATED IN THE FORM OF COLOUR CODES WHICH IS AS SHOWN IN BELOW IMAGES.

15.PUBLICATIONS:

• THE CLASS A SURFACE, TOOLING AXIS, CLASS B SURFACE, CLASS C SURFACE AND SIDE CORE AXIS ARE PUBLISHED AS SHOWN IN BELOW IMAGES.

16.ORIENTATION VIEWS:

• THE ISOMETRIC, FRONT, SIDE AND TOP VIEWS ARE AS SHOWN IN BELOW IMAGES.
