Week 9 - Challenge 3 - Bumper

I CAN'T FINISH WITHIN TIME......

TOOLING AXIS:

• A geometrical set for Tooling Axis is created and base is extracted as referance surface.
• The projection of the Class A surface is taken and from that a bisecting line is formed which is the first referance line for Tooling Axis.

• For second referance line, a line is drawn from and angle of 6 from the center wall.
• Then by bisecting the two lines we get the Tooling Axis.

CLASS B SURFACE:

• For B surface, individual geometrical set is created for the Bumper, Walls and Base.
• Then they are extracted along the geometrical set.
• The extracted surface are then untrimmed and extrapolated by 50mm to form extended surface.

• At last, all the extracted surface are trimmed together and filleted to form Class B surface.

CLASS C SURFACE:

• Mutiple extract is used to form the boundary along the A surface.
• Then the boundary was made into surface by using sweep with and draft angle of 3 by one on the inside and other on the outside.
• The two boundaries were extrapolated and trimmed to form Class C surface.

FINAL TRIM:

• At the final trim part, the A surface and C surface are extrapolated and trimmed together.
• The surface we get above is them trimmed with the B surface to form the Bumper surface.
• Then at part design, the hollow part is converted into a solid Bumper by using closed surface command.

DRAFT ANALYSIS:

• In Draft Analysis tool bar, use the compass and drag it to set along the Tooling Axis of the surface.
• By clicking the surface, it will turn into green colour. if it is blue, the analysis was inversely done which is corrected just by flipping the direction.
• Draft Analysis on the solid part is in green and red regions.
• Individual Draft Analysis is done for both solid and surface.
