Beam - vertical definition

On the Vertical Definition tab of the Beam: definition dialog, you can specify the location of a beam with respect to an active story.

The Beam level list includes all the defined levels of an active story of a building. The location of a beam in a building is defined by selecting a plane (for example, Top - Story 2, Bottom - Story 2). This list also contains all inclined planes defined for a selected story (see: Definition of a plane).

In addition, you can define the reference edge of the beam with respect to the upper or lower level of a story:

When defining the vertical location of a beam, you can define an offset from the lower or upper level of a story. If the offset equals 0, the definition line coincides with the upper or lower plane of a story. Click to select a horizontal element edge that determines an offset value.

A sign convention for offset values has been adopted for both the lower and upper levels of a story:
