Under different circumstances with different catalog items, you want to control how that item is placed in a design and how it relates to other items nearby. Placement properties allow you to specify how items appear in the drawing and how they are related to other items.
You choose the type of placement in a rule when you choose the items involved in that rule. On the Items Tab (Rule Properties Dialog), you can specify the placement type and options for the placement type that you choose.
The following placement type options are available:
None
Use this option for freestanding or non-existent items or for rules that do not pertain to the placement of an item. For example, a rule that prohibits the placement of an item can naturally use None for the placement type.
Geometric
This placement type is frequently used for equipment and equipment components. You can specify rotation and mirroring with this placement type, making it the appropriate way to control how, for example, a nozzle behaves when you place it inside or outside of a piece of equipment. You can select Properties to define the options for this placement type on the Geometric Placement Properties Dialog.
In-Line
Use this option to control how an item is placed in relationship to a signal or pipe run. This placement type is used for inline piping and instrument components. Select Properties to define the options for this placement type on the In-Line Placement Properties Dialog.
Label
Specify this placement type for rules governing the placement of a label on its target.
Snap-On
Use this option to connect items without the geometric implications of the geometric placement type. It is used, for example, to connect an instrument to an instrument. Select Properties to define the options for this placement type on the Snap-On Placement Properties Dialog.
Line Run
Use this placement type for rules governing the placement of line or signal runs.
