r1: r*8: coordinate of plane location
This option allows for the definition of symmetry planes in either moving-source DED or part scale LPBF analyses. For LPBF simulations, the STL file must already have been sectioned prior to importing for use in conjunction with the *SYMM card. The symmetry plane specified must align with the substrate. To override this requirement, use *SYM2.
