General

Name

Enter a name for the report.

Description

Enter a brief description of the report.

Clear Precedences

Select this to clear any precedences that are already assigned to an activity.

Use Distance Lag

Use this to set the lag distance by distance instead of just by time. When this is selected, the Minimum Minable option to set the time at the bottom of the panel will become available.

Activities Filter

Predecessor / Successor Activities Filters

Select filters for the predecessor and successor activities. These lists are populated by the list generated in View > Filters.

Predecessor / Successor Activity Types

Select activity types for the predecessor and successor activities. These lists are populated by the list generated in Setup > Activity Types.

Search Criteria

These result in a conical shape for successors to search for predecessors within the specified parameters.

Predecessor / Successor Point Selection

Select Start Point, End Point, or Closest Intersection to indicate the method of point selection. The precedence will be created from either the start, the end of closest intersection of the predecessor, or either the start or end of the successor.

Optional Offset

Enter a value for the offset and then select the unit of measure from the list.  he closest intersection and optional offset allow the Gantt bars to be split and precedences created between parts of activities. The optional offset only works for design data and is in reference to the nominated point (start, end, or closest intersection).

Bearing

This is the range which is used by the successor activities to search for a predecessor.

Inclination

This is the vertical angle range to be used for successor activities to search for a predecessor.

Radius

This is the distance range to be used by successor activities to search for a predecessor.

Precedence Creation

Closest (Single) or All (Multiple)

Select the method of precedence creation.

Gantt Precedence Type

Select the Gantt precedence type from the list.

Minimum Minable

If there is a lag between the predecessor and successor, enter a threshold for the minimum mining distance and select the unit of measurement.

Precedence Lag

If there is a lag between the predecessor and successor, enter the time and select the unit of measure from the list.
