Use the Draw frame icon to draw the frame section. In this example, we will rotate the local axis of the frame elements by 90 degrees. Select the frame elements that we want to rotate and use Assign menu>Frame>Local axes and type 90 degrees as shown below. After the frames are rotated, they display local axis arrows. Red/Green/Blue arrows correspond to local axes 1/2/3. Click 'Show Undeformed shape' icon to clear the display of the local axis arrows. Local 1 axis (red arrow) is axial/longitudinal direction.
