Polygon Processor - Detailed Features

Polygon Processor Menu Dialog

A menu dialog provides a single point of access to the Netclean, Polygen and Viewflags modules.

Automatic Linework Corrections

As overshoots and undershoots are encountered in the linework, Netclean automatically corrects these misclosures if they are within the user defined search tolerance.

Centroid Generation

Polygen has an option to place a text node at the centroid of each polygon.

Error Flagging

As errors are found in the line network, special flag elements containing an error message are placed at the each location. The Viewflags module automatically centres each selected flag in a view, making error correction simple and efficient.

There are three options available for placing error flags:

1. Flag All Errors: All free endpoints / closure errors are flagged.
2. Use Outer Tolerance: Error flags are placed only if the distance to the
   nearest intersection is closer than a user defined Outer Tolerance
   value. This allows flag placement on genuine errors, without
   creating unnecessary flags.
3. No Flags: No error flags are placed.

Shape Optimisation

Two types of optimisation are available in Polygen. Lines and linestrings are combined where possible. This reduces design file size making polygons faster to manipulate and display. In addition to the above, redundant vertices can be removed from the polygon. NB. The default setting does not optimize the design file.

Batch Processing

Once invoked the Batch mode permits the Netclean and Polygen Modules to be run on multiple files without further user interaction.

Requirements

To run Polygon Processor you will need:

1. MicroStation® V8 and J.
2. Hardware suitable for the above systems.
