AIM : Create the Base Bracket Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model.

REPORT :

Given Class A Surface.

Creation of Tooling Axis :

A point was created in the big circle of A Surface by using the point definition toolbar, in which, circle is selected in the point type.
A plane is created by taking yz plane as a reference and then, creating an intersection with that mentioned plane as reference. Two lines were created by using the point to point line definition as shown in the below picture. And then, a line was created by bisecting those previous inclined lines to create a tooling axis.
Finally, Tooling axis was creating along z-axis which will be used for further in draft analysis.

Performing Draft Analysis : Now, performing the Draft analysis using the Featured Draft Analysis tool. Thereafter, opening the draft analysis tool box and go for the compass option and place the compass alinged to tooling axis.
Creation of Class B Surface : Atfirst, by taking the extract tool, the two ribs and the required surfaces were extracted one after another. Then, by using extrapolation tool, we have increased the lengths of those surfaces upto certain limit, so that the trim operation can be performed easily. So, by using trim operation, the desired surface were found. Then Offset the surface inorder to get the required thickness, here 2.5mm. Now, fillet the required surfaces with required amount which is here (3+\- thickness), according to our need.
Creation of Class C Surface : Firstly, by boundary tool, the boundary provided to the Class A surface and then by using Sweep tool and in sweep tool by choosing the draft direction and then, by giving 3 deg angle with respect to the tooling axis, we created the C Surface.
