What is the "Force attack angle" in Loading table for leg's report

[studboltbkk]

Now I concerning about report of Leg support analysis from Compress, but I have don't understand about "Force attack angle" in the loading table. What is this value and how to clarify this.

Due to the lack of axisymmetric geometry of the leg and lug supports the loading applied to each leg (or lug) will vary depending upon the direction that the wind (or seismic) force is applied in. COMPRESS takes this into account when determining the maximum loads applied to the supports.
