A load point, also commonly referred to as a cardinal point, defines the location where the software displays the profile cross-section on the member line. There are 15 load points definable for a cross-section symbol, but only one at a time is used when the profile is placed.
-
Open the symbol.
-
Click Add Point Properties
on the Cross Section Symbols toolbar.
-
Select rows in the grid until the point to define as a cardinal point highlights graphically, or select the point in the graphics window.
-
In the Point name box, select Load Point.
-
In the Attribute setting box, type the cardinal point number for the highlighted point.
-
Click Apply.
-
Continue defining cardinal points until you have assigned all 15 cardinal points.

Click File > Save.
There are 15 cardinal points. The location of cardinal points 10 (center-of-gravity)
and 15 (shear center) depend on the section shape. The local z-axis of the member
and the center-of-gravity point of the section define cardinal points 11 and 14. The
local y-axis of the member and the center-of-gravity point of the section define cardinal
points 12 and 13.
