This tool separates the assembly into single beams.
Each beam then gets its own system line. The single axes are overlapped and each beam has an offset value.
Note: Before creating BOMs and drawings, you must separate the compound sections into single beams. Otherwise, they are treated as one beam and this would result in an incorrect quantity of beams in the BOM.
