OBJECTIVE

To create the Base Bracket Plastic component through the given Class-A surface and conforming with the Draft analysis on the model.

GIVEN INPUT

CLASS A SURFACE

CREATING TOOLING AXIS

To create the "Tooling Axis" for the component, we need to carefully examine the class A surface. For the given base bracket, the Z-axis is the most suitable tooling axis. I started by creating a dummy tooling axis on the Z-axis, taking into account the reference point in the center of the circle.

CLASS B SURFACE

To create Class B surfaces, we first extracted the surfaces from Class A and then untrimmed them to obtain the original parent surface. The next step was to offset these surfaces to the required thickness and then trim them into the desired shape. Finally, we added the necessary fillets to achieve the desired result.

CLASS C SURFACE

A Class C surface is a combination of Class A, Class B, and Class C surfaces used to create a solid body. To make a Class C surface, I utilized the sweep command and selected the outer boundary of the Class A surface. I then used the 'line' command under the 'profile' block and chose the subtype 'with draft direction.' After selecting the tooling axis and giving a 3-degree angle, I swept the direction inside down arrow, with the Class B surface under the Class A surface. This process was repeated for the two circles on the Class A surface. Finally, I joined all the sweeped surfaces using the 'join' command and trimmed the Class A, Class B, and Class C surfaces to create a closed surface and ultimately a solid body.
