Beam Action Coordinate System
Loads applied to beams act through the beam action coordinate system (BACS). Forces and moments transmit to beams at beam connections through the BACS.
The origin of the BACS is on the curve that the software draws as a blue line when you create a beam. The X axis of the BACS is parallel to the axis of the beam. You control the direction of the Y and Z axes of the BACS by setting the Y direction on the Beam Definition dialog box.
