The build direction is the global z-direction by default. If another direction should be used, the part has to be rotated accordingly. of the Principal Coordinate System. For each scenario under Build Direction the build direction can be easily rotated. Then the build direction for the Design Rules as well the material properties are rotated accordingly.
The only exception to this are symmetrical optimisations, for them the build direction is the positive z-direction of the symmetry coordinate system. Attention: The Material Coordinate System does not have an impact on the build direction for the Support Reduction! The build direciton entry in the scenario refers only to the Material Coordinate System and has no impact on the Support Reduction!

build direction shouldn’t be normal to a symmetry plane.

General Explanation
For different applications there are different priorities and for some the manufacturability is specially high. Therefore, it would be nice to push designs in a direction where the manufacturing gets easier without costing to much performance regarding the efficient design and material allocation.
