Week 8 - Challenge 3 - Coin Holder Design

DESIGNING A COIN HOLDER USING CLASS A SURFACE

Design procedure:

• Creating tooling axis for class A surface
• Add draft angle
• To create base
• Creating B surface
• Creating C surface
• Use closs surface to create solid part model.

Tooling axis:

For coin holder use line at midpoint of the extraced plane(Class A) to create tolling axis.

Draft analysis:

perform draft analysis to check if a part has required draft or not. Use feature draft analysis to perform this analysis.

Class C surface

Create side walls by using extract from the class A surface, untrim them and extrapolate using point continuity. Then suing surface trime remove the unwanted edges.

Give the necessary fillet using fillet edge

Base:

Use base of the class A and extract, untim and extraopolate use surface trim to clear the extra edges.

offset the surface before trimg is performed.

use same approach to create outer flange then offset it towatrs inwords

Create class C surface, extracr boundry to sweep at 90 degree with referance boundary.

Join all the three surface to form surface of the coin holder, jump to part body workbench and close surface.
