Tooling Axis:

creating the Tooling axis, I performed a draft analysis for class A to check the draft angle for it.

Draft analysis for class A surface:

I selected the featured draft analysis tool in the design.I click on the 'use of the compass to define the new current draft direction' to align the compass to the tooling axis. Once the compass is aligned the compass to the tooling axis, we need to select the surface to perform draft analysis. Class A surface will be highlighted in green colour.

draft angle is 3.0 deg

draft angle is 0.8deg

Class B surface Creation

create the class B surface for the door handle, I offset the class A surface to 3.0mm inside.

Class C Surface creation:

I used the sweep command in the geometric shape design workbench to create the class C surface.

Class A+C surface join:

Class A+C surface join AND B trim:

Closed body:

Creating Solid body:

To create the solid body.

RIB Design:

To create the ribs on the solid part body I create a line sketch for the rib and I extruded it in the tooling axis direction and I thicken the extruded surface to 1mm toward the inside.extruded surface I gave 0.5deg of draft angle to the rib, and I union trim the rib with the part body to remove the extra surface of the rib, by union trimming the rib with the part body the rib gets added to the main part body.
