Beam and column in a plan with the shape handles displayed
You can adjust the endpoint location of a beam using shape handles. This lengthens or shortens the beam.
The other end of the beam remains fixed.
Shape handles change geometry along the axis of the component. To move a beam out of its original axis,
click and drag the beam into a new position.
Shape Handle Properties
Each beam shape handle provides properties that can be changed, based on the element type preferences.
To access the shape handle properties, right-click the back-to-back triangles, and select View Properties. For
more information, see View Properties on page 210.
