Horizontal Leg

This setting controls the desired length of the horizontal leg.

Thickness

This setting controls the overall thickness of the entire angle shape.

Distance K

To determine the exact "K" value for a given shape, you should consult the AISC "Manual of Steel Construction." A general rule of thumb is that the "K" value is roughly double the flange thickness (+/- 25%).

Length

Input a length for the Beam.

Rep

Choose a Representation for the shape:

• Top - Creates a 2D top view of the shape. You will be prompted to digitize the shape bottom or center (depending on the type of shape).

• Wire 3D - Creates a 3D wireframe view of the shape. You will be prompted to digitize the bottom or center of the shape (depending on the type). The shape will be generated in the -ZV direction in the current construction plane.

When complete choose OK or if you are editing an existing structural shape choose the Edit or move options
