Week 9 - Project - A pillar Design with Master Section

OBJECTIVES:

• To create the class B and class C surfaces from the given class A surface
• To form a solid geometry by combining all the surfaces
• To create a dog house for the solid part whilst following the design rules
• To perform draft analysis on the class A surface and the solid part model

MASTER SECTION:

Master sections are the guides for design requirements which decide the component packaging after the styling surface

PRE-DEFINE OF CLASS-A SURFACE:

Before starting the creation of the class B surface we must ensure that the given class A surface is properly closed and the surface continuity is proper. This can be done either with the help of the join operation or by using the boundary feature.

TOOLING AXIS

• Extract the bottom surface, and add point on the surface.
• From the Mastersection, extracted dog house section and create bisecting Line along on the bottom surface point
• that Bisecting line as a tooling axis of the class A, with determine Class A surface by Draft analysis along with the tooling axis

Picture of Tooling axis

• While draft analyse the class A surface, some where the surface angle is 1.993 degree
• so, change limit from 3 degree to 1.9 degree

Class B Creation

• Offset the class A surface to 2.5mm thickness of the component.
• somewhere of the surface is broken to continue from class A

• by selecting the boundary of the offset surface with limits where surface is broken.
• then using sweep, with reference surface broken surface is reconstruct

• then join, sweep surface to the offset surface and Class B is created

Class C Creation

• From the Class A surfaces using Boundary command to all edges of the surface
• then sweep those section by define by reference surface with guiding of boundaries
• sweep at the angle of 90 degree at distance of 7mm
• then one sweep to another edges are extrapolate 2mm and trim those edges.
• after that join all Sweep section of the surface and considered as Class C surfaces.

FINAL Door Trim Lower Creation

• Join Class A and Class C surfaces
• Then Trim Class B and Join of (Class A and C surfaces).

Dog House Creation from the master section

• From the bottom surface point, add axis system and positioned sketch
• projection the mastersection of dog house with isoconstraint
• Then extrude both side and mastersection of dog house edges is projection
• then extrude and extrapolate required length
• after that trim all surfaces and thicken inward of 2.5mm wheather measure from mastersection

Side Core Axis creation

• Add plane on the dog house top surface and positioned sketch
• projection of corner two edges and draw bisecting line is called Side core axis

• Then create horizontal flange and ribs in the dog house, thicken 1mm is measure from mastersection
• afterthat draft angle of 0.5 degree along the side core axis
• Edges are fillets 0.5 inner portion of dog house and Ribs 0.25mm
• outer edges are fillets 2.5mm

• Union trim to the main component and Key slots are create
• then remove to main component

Draft Analysis

• Draft analysis of dog house along side core axis there drafting angle is 0.5 degree.so, limit as been changed to 0.48 degree
