Challenge is to create a bumper of 3mm thickness from the given Class A surface Checked the class A surface for gaps using boundry command Draft analysis for class A with respect to tooling axis. full bumper draft analysis   Part after closure surface     Tooling axis Interesection line of the Class A surface…

Challenge is to create a 2.5mm wall thickness plastic component from the given Class A surface.  Pictures of the Part produced by Close Surface. Tree structure details below Below the details of tooling creation. First a boundry was created to check the surface gaps and found no gaps. Then intersection curve was created…

Challenge is to create Class B and Class C surface using the received Class A surface and finally create close surface. Switch Bezel part pictures below.     Draft analysis with 3deg of the final closure part "Switch Bezel" other side of draft analysis       Draft analysis and Tooling axis. Side…

Challenge is to create plastic component with given Class A surface. also to generate tooling axis and draft analysis. First the generation of tooling axis Next draft analysis with respect to tooling axis. Here only the one axis is considered for draft analysis as the other two axis is not feasable practically.   Tooling…

Challenge is to Complete Back door assembly by creating inner panel and relative reinforcement brackets. Opened the given skin data "Back door" file in NX. First checked the skin surfaces by joining them by sew command. Where ever joining failed, blends points were hidden and new blends were created by blend surface or…
