Creating FS Links

The simplest kind of [anchor]link[/anchor], the finish-to-start (FS), represents a relationship where the successor cannot start before the predecessor finishes. If the predecessor and successor overlap on the timescale, an embedded node must be placed first. For more information, see [bookmark postid=”5570″ anchor=”embedded”]Using Embeds to Create SS & FF Links[/bookmark].

FS links can be created between activities, milestones, and benchmarks, either in pairs or for multiple activities. However, the regular [icon_cmd]Link[/icon_cmd] icon can only link two objects at a time. If more than two objects are selected for linking, an error message will open. When linking multiple activities, the FS Link Chain icon must be used. Instructions for both are provided.

NOTE: For diagonal links, only the vertical or horizontal portions may be selected.

Steps

Two Activities

  1. With the Select Tool  Select Tool Icon chosen in the toolbar, select the first activity, milestone, or benchmark on the canvas
  2. Press and hold the Shift key and select the second activity, milestone, or benchmark on the canvas. Alternatively, you can click on a blank portion of the canvas and drag a rectangular marquee box around both objects, so long as it includes only the two desired objects for linking.
  3. With both objects still selected, click the Link icon Vertical Link Icon in the toolbar.
  4. Once linked, both objects remain selected. To de-select, click an empty portion of the canvas.

Multiple Activities

  1. With the Multi-Object Select Tool Multi Select Icon chosen in the toolbar, select the first activity, milestone, or benchmark on the canvas.
  2. Select the second activity, milestone, or benchmark on the canvas. Alternatively, you can click on a blank portion of the canvas and drag a rectangular marquee box around all objects, so long as none of them overlap on the timescale.
  3. Repeat step 2 for each object, as needed.
  4. With all the objects still selected, click the FS Link Chain icon FS Link Icon in the toolbar.
  5. Once linked, all the objects remain selected. To de-select, click an empty portion of the canvas.

Properties

Field Definition
Logic A label for categorizing links. The designation is for supplemental information; it has no bearing on actual schedule logic or calculations. For a breakdown, see below.
Geometry The physical shape of the link. A link can bend vertically, horizontally, and diagonally, in eight different combinations. NetPoint makes use of a scoring system to identify the best possible geometry for a link. For more information, see [bookmark postid=”5572″ anchor=”scoring”]Link Geometries[/bookmark].
Lag A way to enforce a minimum gap. For more info, see [bookmark postid=”5574″ anchor=”link-offset”]Adding Link Lags[/bookmark].
[anchor]Logic [/anchor]Types
Type Definition
Hard A relationship that is inherent to the nature of the work being done.
Soft A relationship that is a preferred choice.
Resource-Flow A relationship that is based on resource usage.
External A relationship that is mandated or dictate by an external source, such as a governmental agency.
Contractual A relationship that is mandated or dictated by a contract.
Special A relationship that is unique to the schedule.

Displays

Field Definition
Gap The duration of the link.
Lag Notation The value of the lag. If the gap is equal to zero, it will automatically turn off, even if the box is checked for display.

Attributes

Field Definition
Predecessor The object the link is emanating from. This field is just an indicator and cannot be edited.
Successor The object the link is merging into. This field is just an indicator and cannot be edited.
Relationship The type of link. This field is just an indicator and cannot be edited.
Score A point value based on how many grids the link passes through, or if it crosses over other objects or overlaps with other links, for example. For more information on scoring, see [bookmark postid=”5572″ anchor=”scoring”]Link Geometries[/bookmark].
Validity An indicator of whether or not the link is valid or redundant. For more information, see [bookmark postid=”9346″ anchor=”redundant”]Treating Redundancies[/bookmark].
