Using the Distance option, you can define minimum distances between objects in drawings and define default lengths for various entities in drawings in a plant.
You can define default distances or lengths for each of these values:
Label offset
Defines the default distance between a label and the component being labeled. When you create the label using Catalog Manager, you can change the values of the Offset Source and Offset Distance properties to override this value.
Minimum connector segment
Defines the minimum length for connector segments (that is, the shortest length of pipe or signal run that can exist). However, the design software overrides this distance when you place piping components together. The line created between two touching piping components is zero-length. The greater of the Minimum Connector Segment and Routing Self-Avoidance settings governs the shortest line length when, for instance, routing a line from a nozzle.
Routing self-avoidance
Defines the distance between a line route and an object that the line is avoiding. This setting also governs how long a segment must be in order to place an inline component into it. When you place a line in your design, the self-avoidance setting is applied. If you later change this setting, the change affects only those lines created subsequent to the change. The original self-avoidance distance remains a characteristic of any line after it is created. You can use the delivered utility, ApplySettingsCmd.dll, to update existing lines with the next value.
