Dependencies tab

The Dependencies tab lets you define the dependencies to display in the plot, and how to display them. For example, you can display no dependencies, only predecessors, only successors, or both. The table below describes the options in the Dependencies tab:

Section

Option

Purpose

Display Dependencies

None

No dependencies display in the plot.

Predecessors

Only predecessors display in the plot.

Note: Predecessors display as red arrows pointing to the predecessor for selected record/s. For 'OR' dependencies, predecessors display as light pink arrows.

Successors

Only successors display in the plot.

Note: Successors display as blue arrows pointing from the successor records for selected record/s. For 'OR' dependencies, successors display as light blue arrows.

Both

Predecessors and successors display in the plot.

Show dependencies for selected records only

Displays the dependencies for currently selected block/s.

Show chained dependencies

Displays the chain of dependencies for currently selected block/s. For example, you may want to see the extended network of dependencies.

Note: This check box is only active if you selected the Show dependencies for selected records only check box.

Maximum chain length

Lets you limit the network of dependencies by typing a value for the maximum value chain, for example, 3. Otherwise, XPAC displays the complete network of dependencies.

Note: This check box is only active if you selected the Show chained dependencies check box.

Display all rule sets

Select rule sets that you want to display. Either:

•	select the Display all rule sets check box to include all rules; or

•	select the check box for each rule set that you want to display.

Arrow Settings

Low Quality

Generates 2D arrows (recommended for large plots).

High Quality

Generates 3D arrows.

Head Size

Specifies the size of the arrow head in project units, for example, 10.

Shaft Size

Specifies the shaft size of each arrow in project units, for example, 2.

Note: This option is only active if you selected the High Quality arrow.

Position arrow head away from block centre

Moves the head away from the centre of the block. This may be useful if a number of arrows are coming in or out of a block.
