Week 8 - Challenge 4 - Bumper

primarily the class A surface is imported. then the tooling axis is made which is nothing but the normal to the top surface. this axis is the direction through which the core and cavity seoerates each other. after this the Class B surface is made. it is the offset of the class A surface in ehich it is offsetted inwards. While offsetting there will be few missing surfaces. these surfaces are edited by using surface tools. Once these surfaces are created and merged into a single surface, the class C surface has to be done. For the class C surface the boundary is extracted. this boundary is then swept by using the sweep command , with draft direction along with the surface reference option with 90 degrees. then all the surfaces are trimmed and made as a closed surface. this is the final surface made. then the draft analysis is done along with the tooling axis direction.
