So we've given descriptions to five BLC's. These descriptions are strictly for your

Load Direction Options
RISA-3D allows you to specify the direction of your loads in different ways. The
three basic choices are:
1.) Apply loads aligned with global axes, designated with upper case labels such

2.) Apply loads aligned with member or plate local axes, designated with lower
case labels such as x, y and z.
3.) Apply projected loads along global axes, designated with upper case labels
such as L, V and H.
You will be presented with a list of options each time you define the loads so
don’t worry about remembering what they are. A click of the Help button will
explain the options each time you need it.
