Week 9 - Project - A pillar Design with Master Section

Report

Aim: create solid body of B pillar with ribs and locators using the given A class surface and master section.

Procedure:

1. import geometry input: given A class surface and master section

2. create tooling aixs

extract 2 groups of lines from 2 master section

find midpoint, create tooling axis in y direction

draft analysis

3. create class B surface

measure the distance from master section, we know part thickness is 2mm. Offset class A 2mm to get class B surface. locally fix the surface here

use sweep method to create flange for class B surface

when offset surface, there is an error, need to fix locally

do the same for the other side

trim flange with class B surface, give fillet 2.5mm.

offset flanges and create class A surface with flange. Now we have both class A and B with flanges

4. create class C surface

extract all lines on boundary of class A surface

sweep and extrapol them

trim them all to get class C surface

5. create closed surface

trim class A, B and C surfaces to get the closed surfaces

6. create solid body with closed surfaces

Draft analysis

7. Create b surface feature

ribs

create sketch and extrude

thicken and trim, give a draft angle

dog house

create sketch on the plane

thicken surface

trim dog house to avoid sink mark

create sketch for clip

pad sketch

give fillet and draft angle

make symmetry to the other side

final result

draft analysis
