The following are common rules applicable to all diagrams:

  • The diagram has a recommended maximum size of 1300px x 620px (to fit on a typical laptop screen without scrolling) and an absolute maximum size of 4960px x 3508px (A3 print at 300PPI). The following table summarises the recommended sizes for the number of elements assuming landscape.
Number of objects Size 72PPI 100PPI 300PPI
less than 6 A5 595 x 420 827 x 583 2480 x 1748
less than 15 A4 842 x 595 1170 x 827 3508 x 2480
less than 30 A3 1191 x 842 2653 x 1170 4960 x 3508
reommended screen   1300 x 620  
  • A small gap (e.g. one grid square) should be allowed between the edge of the diagram and the elements. (This is because some SysML tools resize the diagram to enforce a gap.)
  • The fonts should not be changed from the default, this is controlled by the shared SysML modules (the ISO directives state 8-11pt and the MagicDraw default is 11);
  • There should be no 3D shadow and no colour gradient fill.
