DOOR HANDLE

1.CHECKING THE CONTINUITY OF GIVEN CLASS-A.

HERE I USED BOUNDARY COMMAND AND THEN DISASSEMBLE IT TO GET A SINGLE CURVE,

THEREBY CONFIRMING THAT THERE IS NO DISCONTINUITY.

2.CREATION OF TOOLING AXIS.

HERE I HAVE VISUALLY CHECKED THE THREE AXIS (X,Y,Z),THAT FOR WHICH AXIS ALL THE FACES ARE CLEARING,ONE WAY TO CHECK THIS IS BY CREATING DUMMY TOOLING AXIS AND VIEW IT IN NORMAL MODE.HERE I HAVE CREATED TOOLING AXIS IN Y-DIRECTION.

CLASS -A

3. DRAFT ANALYSIS:-

IN ANY COMPONENT, DRAFT IS GIVEN AS TO EASE IT'S EJECTION FROM MOULD.

MIN DRAFT FOR PLASTIC COMPONENT IS - 3 DEG

FOR RIBS & SCREW BOSS - 0.5 DEG

*NOTE - HERE AFTER CHECKING MULTIPLE TIMES MY TOOLING AXIS, IT IS THE CLASS-A WHICH IS NOT PROPER IN SOME AREAS,THAT;S WHY DRAFT ANALYSIS IS NOT PROPER.
