Hello Community

My model consists of a symmetric cruciform arrangement of a single column with two cantilever beams connected either side to the column flanges by flush Endplate (1st pic). Since the geometry under consideration is symmetric, I am modeling only one-quarter of the structure (2nd pic). To define the symmetry, I created boundary condition X symmetry at beam, column and endplate cross-section (3rd pic) and boundary condition Z symmetry at column web cross section (4th pic & 5th pic). 

Is my approach correct to define symmetry?
