Structural framing tags with attachment points of <None> are available to only the Middle location settings
provided they rotate with component.
These specifications also apply to the <Load Structural Framing Tag> option, which opens the Load Family
dialog (see Loading Families on page 427).
To appear in the Structural Framing Tag list, loaded families must follow these guidelines.
Spot Elevations
The Spot Elevations tool allows the placement of spot elevations when the type parameter Rotate with
Component is selected. This is similar to tags in that they are filtered by this parameter.
Beam Elevation (Project) calculates elevation from the lowest level of the project.
Create/modify types gives you the option of creating a custom spot elevation. When selected, the Family
Type Properties dialog opens to edit the spot elevation tag.
Beam Elevation (Relative) enables the Relative Base drop-down list, which allows selection of the base relative
level for elevation calculation.
NOTE Only one spot elevation type can be placed at a time. If you change the spot elevation type in any of the
12 locations (6 for the level and 6 for sloped), it will change all 12 spot elevation type settings in the Beam
Annotations tool.
The Display Elevation drop-down list selects the location of elevation measurement on the beam.
