Report
Ribs
Ribs are a feature in plastic injection molded parts. They are thin extensions that run perpendicular from a wall or plane. They are commonly used to provide additional support and strength to a part.
Screw Bosses
Boss features are commonly found in injection molding designs. They are used to aid in the assembly of molded parts by providing a channel for a screw.
Tooling Axis
Tooling axis is a direction in which core and cavity opens and closes. Draft angle is provided with respect to the tooling axis. While creating mold component from Class-A surface, we need to decide the tooling direction. It can be decided by visual inspection, deciding complex surfaces and bisecting method.
Class A Surface
Draft Analysis of A Surface
NOTE
In some of the edges and corners of the class A surface we are not getting the clear drafting angle it shows a pop up error.
The Class A surface has only a draft of 0.5 degrees, hence it is not clearing for 3 degrees draft angle.
Class B Surface
Class C Surface
