Step 6: Definition of optimisation parameters and Generative Design Settings
The optimisation parameters are selected in the Studies Area as well.
Now the Build Direction will be adjusted. Therefore the Build Direction Tool can be activated with the coordinate system symbol and any surface can be selected. To rotate the Build Direction either the visualized coordinate system can directly be manipulated to align the Build Direction with the x-Axis of the model or the Euler Angles can be entered directly (90,00 °; 90,00 °; 270,00 °).
For each scenario the Build Direction can be easily changed, then the Build Direction for the Design Rules as well the material properties are rotated accordingly. This way multiple Build Directions can be checked in one project. Afterwards the optimisation results can be compared in the Post Processing and the best build orientation can be picked

In case of anisotropic material stiffness and the directional dependent Tsai-Wu transversely isotropic Failure Criterion with huge material property differences for the in-plane directions and the build direction, as well for the maximum allowable tensile and compression strength, the optimisation may not give stable results. How to handle this here. |
