Extract CAD from composites optimization

Recommended Posts

Hi Optistruct users,


I am currently working on a Formula Student Composites Chassis.


My chief designer asks me to extract the CAD file from my composites optimization, in order to have right thicknesses everywhere in the chassis, and starting to place other elements around the chassis according to the FSAE rules.


But I know that i'm working in 2D, and the only way to see my final laminate is to click on Element Representation.


So basically, I am asking for advice on how to export my simulation into 3D CAD.


Thanks for helping,

Hi Nicolas,


Extract the ply shapes as surfaces with Aerospace profile - Ply geometry smoothening.

Then thicken it to the desired thickness.




Use Aerospace profile - Shell to solid conversion, and then you can extract surface mesh from 3d mesh using FACES option in HyperMesh.

Go to Tool page>> FACES>> Select elements/components>> find faces


I hope it helps,

Best regards,
