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 the Build Direction can be easily rotated and is then used for the Design Rules as well as material properties.
The only exception to this are symmetrical optimisations. In this case, 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!

shouldn’t be normal to a symmetry plane and has to be considered during the model setup. If all three symmetry planes are active, the Support Reduction shouldn’t be used.

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.

In the following graph the influence of the strategies is illustrated. It can be saved up to 78% of support volume with activated Support Reduction. As a trade off the mass of the part increases. Because more material is used the part gets a little bit stiffer.
