DESIGN

GIVEN CLASS A SURFACE

By using Bisecting line command to create a Tooling axis

FINAL TOOLING AXIS

BASE BRACKET DESIGN PROCEDURE

CLASS-B SURFACE

RIB CREATION

Bringing in the class-A surface.
Extracting the rib surface.
Un-trim the extracted surface.
Extrapolate the un-trimmed surface.
Trim the surface as per the required shape.
Repeat steps 2, 3, and 4 for the next rib surface.
Offset the created rib surfaces for 2.5mm. ( CLASS-B SURFACE)

MIDDLE FLAT RIBS CONNECTING SURFACE

Extract the middle flat connecting surface from class-A.
Un-trim the extracted surface.
Extrapolate the un-trimmed surface.
Offset the extrapolated untrimmed surface for 2.5mm.
Trim the surfaces. (CLASS-B SURFACE)

CREATION OF BASE SURFACE

Extract the base surface from the class-A surface.
Un-trim the base surface.
Extrapolate the base surface.
Offset the base surface for 2.5mm
Trim the base surface from the middle surface which is already created.

JOIN

Join all the class-B surfaces to make them as one unit.

FILLET

Since the class-B surface is 2.5mm downwards to the class-A surface need to add this offset distance with the filleting radius observed from the class-A surface.

CLASS-C SURFACE

This is the connecting surface of class-A and class-B surfaces.

Create the boundary of the class-A surface using the boundary command.
Use sweep command to generate class-C surface along the draft direction with 3 degrees drafting angle concerning the tooling axis.
Extrapolate the hole features from the class-A surface and trim them.
