If an intersection is not directly requested, the command “noIntersection” can be added to the Advanced User Settings. In some cases the Design Space of the optimisation is not the one the intersection should take place with and therefore this additional command can be used. The intersection is not done for the iteration but the result is the smoothed optimisation design. For further information regarding a separate intersection with MSC Apex Generative Design have a look here.

Disable automatic Non-Design Surface Detection
Per default all Non-Design surfaces grow a little bit beyond their boundaries to ensure a trouble-free and clean intersection. This is done with an automatic detection of Non-Design faces. Sometimes this can lead to issues.
This automatic growing can be deactivated with the Advanced User Settings command below:
automaticFunctionalFacesDetection.positiveNonDesignDirection=false |
|---|
Be aware that you have to apply Machining Allowance on all functional surfaces to ensure sharp edges and functional surfaces after the intersection. When no extra material is needed for the post processing of the part a Machining Allowance of 0 mm should be added.
