107 -- Summary of Display Priorities --
109 -- Structure display priorities control the order in --
110 -- which structures are redrawn. --
112 -- When you display a structure, you specify its --
113 -- priority. The lower the value, the lower the --
114 -- display priority. When the display is regenerated, --
115 -- the structures with the lowest priority are drawn --
117 -- For structures with the same display priority, --
118 -- the order in which they were displayed determines --
119 -- determines the drawing order. --
121 -- CAS.CADE supports 11 structure display priorities, --

167 -- are drawn first. For structures with the same display
168 -- priority, the order in which they were displayed
