Beam Orientation Definition Dialog Box
Use the items on the Beam Orientation Definition dialog box to specify the orientation of the BSCS relative to the BACS. To see how the values you enter here affect the orientation of the BSCS relative to the BACS, it may be helpful to view the example of shifting the shape origin or shifting the shear center. Click Refine Model. Click the arrow next to 
Beam. Click 
Beam Orientations to open the Beam Orientations dialog box. You can also access this dialog box by clicking New on the Beam Orientations dialog box. The Beam Orientation Definition dialog box includes these items:
Beam. Click Beam Orientations to open the Beam Orientations dialog box. You can also access this dialog box by clicking New on the Beam Orientations dialog box. The Beam Orientation Definition dialog box includes these items:• Name—Enter a name or accept the default name, BeamOrientx, where x is a number that Creo Simulate increments by 1 with each succeeding definition.
• Description—Enter an optional description. After you complete the beam orientation definition, the description appears in the Beam Orientations dialog box when you highlight the orientation name.
• Orientation Angle—Specify the angle to rotate the BSCS about the BSCS X axis.
• Shape Origin, Shear Center—Select one of these as the attribute for Creo Simulate to offset. The software uses the values you enter for DX, DY, or DZ to offset the BSCS from the beam action coordinate system (BACS).
◦ Shape Origin is the point of origin of the beam shape coordinate system (BSCS).
◦ Shear Center is the point on a beam section about which the section rotates under deflection. For many of the standard beam sections, the shear center is coincident with the shape origin. Channel sections and L-sections are exceptions. For channel sections, for example, the shear center is below the shape origin. You can view the offset of the shear center from the shape origin when you define or edit your beam section by reviewing beam section properties.
• DX (FEM mode only)—Offset of the BSCS X axis from the BACS X axis. The offset occurs along the direction of the BSCS X axis.
• DY, DZ—Offset of the BSCS from the BACS along the axis direction of the BSCS.
