Place Cantilever Segmental tool

Used to place a balanced cantilever segment from a template.

Found on the Home ribbon tab in the Superstructure group.

Tool Settings

Balanced Cantilever group
Template Name Click […] to open the Template Selection dialog, which is used to select standard templates.
Build Order Type a integer to indicate the order which this balanced cantilever is placed. The build order of all the balanced cantilevers is utilized by analysis programs, such as RM Bridge, in staged construction analysis.
Tip: The value will be automatically incremented by one from the previous build number placed.
Start Station Offset Type a distance to use as the offset from the selected supportline along the alignment.
Horizontal Offset Type a distance to use as the lateral offset (transverse to alignment).
Seg. Length Type the number of segments at a given length.

A vertical bar ("|") is used to differentiate the segments for back and ahead stations, in that order. A space (" ") is used to vary segment lengths within the back or ahead balanced cantilevers.

For example, type 4@4|2@5 2@3 to place:
  • four segments, each four master units long, back station (total of 16 master units)
  • two segments, each five master units long followed by two more segments, each three master units long, ahead station (total of 16 master units)

Pier Seg Length Length of the pier segment or segments.
  • A single value results in a single segment of that length, centered over the supportline (adjusted by Start Station Offset value).
  • A pair of comma separated value results in two segments, with those corresponding lengths back and ahead station, respectively.
  • No value or zero results in no pier segments placed.
CIP Length Length of a cast-in-place segment placed at the end of the balanced cantilever.

Solid Placement group
Template Orientation Specifies the orientation of the faces of solids placed along the alignment.
  • Vertical — the template faces are vertical in the Z axis (world coordinate system) (i.e., "plumb").
  • Normal — the template faces are perpendicular to the alignment

Template orientation: a) Vertical (in Z axis) and b) Normal (to alignment)

Feature group
Feature Definition Select an existing feature definition from the drop-down list to use for object being placed.
Name Prefix Type a prefix value to use for all objects set using this Feature Definition, which are useful in quickly identifying features in a group.
