In this example, the customer tries to export an assembly as a STEP file, using the "All simplified" option for parts and assemblies.
The resulting STEP does not contain any simplification, but instead shows the bodies as "All designed".
SolutionIf the top level assembly contains a simplification which the customer wants to export as such, then they need to ensure the "Assembly simplification" option is set to "Top Level Simplification", see screenshot below.
