, press

ENTER

The data for this load direction is displayed on the command line, as
follows:

Effective moment of inertia for this load direction: 2.341e+004

Angle of deflection: 266.5

Maximum distances neutral line - border:

Extension side: 16.690 Compression side: 14.444

Enter a description for the calculated profile and locate the block with
the calculation data in the drawing.

Respond to the prompts as follows:

Enter description:

Enter

Frame Profile

, press

ENTER

Specify insertion point:

Place the calculation block next to the profile

Your drawing looks like this:

NOTE

The main axes, 1 and 2, are the axes with the most and least deflection.

The F arrow displays the direction of the force, the s arrow displays the
resultant deflection. The moment of inertia block shows the moments related
to the main axis, the maximum distances from the edges, and the calculated
area. For more detailed information, see Help.
