Inference Rules - Proximity Testing (Distribution)

Parameter	Description
Ignore pipe intersection angles	Applicable to Merge Nodes (Inline Proximity) only. By default, pipes to be connected must have difference in bearing greater than 45° (to prevent connection of parallel pipes). Check this option to ignore difference in bearing between pipes when merging nodes.
Search Radius	Search distance from node.
Nominal Diameter Match Tolerance	Pipes will only be joined during proximity testing, if the diameters of the pipes to be joined are within Nominal Diameter Match Tolerance.
Elevation Match Tolerance	Nodes will only be merged during proximity testing, if the elevations of the nodes are within Elevation Match Tolerance.
Include Object Types	Only node types checked in the Include Object Types section of the rule will be considered for merging.
Match Attributes	Check the options in the  Match Attributes section to restrict joining of pipes to pipes with the same Date Installed and / or Material.

The Merge Nodes (Inline Proximity) rule is used to search for pairs of nodes connected to one pipe within a user defined Search Radius. If the nodes / pipes found satisfy defined parameters, the nodes will be merged, therefore joining the connected pipes.

If a fitting node is merged with another node type, the non-fitting node attributes will be kept in preference to the fitting node attributes.

Merge Nodes (Inline Proximity) example

For merging to take place, in addition to satisfying the parameters specified in the Inference Editor, the following rules must be satisfied:

1. Only one node found within Search Radius that is connected to only one pipe
2. Pipe to be connected must be connected to two nodes
3. Pipe to be connected must have difference in bearing greater than 45° (unless Ignore pipe intersection angles option is checked in the rule parameters)

When running the Merge Nodes (Inline Proximity) rule for Node B with Ignore pipe intersection angles unchecked: If Node C is found, merging will take place as the difference in bearing between pipes A-B and pipes C-D is within the allowable limit. If Node E is found, merging will not take place as the difference in bearing between pipes A-B and pipes E-F is outside the allowable limit.

The Merge Nodes (Proximity) rule is used to search for nodes connected to one pipe within close proximity of one another and coalesces them into a single node.

InfoAsset Manager searches for nodes within a user defined Search Radius of each other.  If the nodes found are within user defined diameter tolerance and elevation tolerance, the nodes will be coalesced into a single node.
