A symmetry condition (zero normal displacement, zero rotation about the in-plane axes) on a datum plane normal to X, Y or Z, with its set given or made of the open design's faces on the plane (a partition's cut faces), so half a symmetric part is solved as a half. Half a 40 mm bar cut at its mid-width, with the condition and half the load, bends as the whole bar to 2e-12 with half the reaction. Inclined planes are refused as not supported yet.
