Background: It is a fancy o-ring. It is a part for a carburetor. It is a face mount application, squished between two parallel flat plates. Manufacturing process and molds are similar to o-rings molds. Gasket material is a type of rubber used for o-rings. I have a 2D drawing of the flange, and I have made a crude 3D drawing of the gasket using Punch Via Cad Pro v.6 (this is good for visualization, but no good for machinists). Task: Make a parametric solid model. Finished model to be exported in some standard file formats. Three years ago, some random machinist was happy with {*.STL, *.WRL, *.SLDPRT} which were exported from Solidworks. That machinist produced a 16-32 micron finish on his molds, so the granularity of your parametric model needs to support that.

Background: It is a fancy o-ring. It is a part for a carburetor. It is a face mount application, squished between two parallel flat plates. Manufacturing process and molds are similar to o-ring molds for rubber. Gasket material will be a GF type FKM with 70A Shore hardness. The flange has lots of extra fill space, because it was designed for nitrile touching automotive fuel.

The o-ring cross section is .090 inches at rest, and it gets compressed laterally during assembly to .076 inches thick. As it is being compressed, the part rescales itself and tries to pull its own ears off. Other than that, there are no obscure constraints for design. Task: Make a parametric solid model.
