About Pathway Robustness

If your pathway design is not physically feasible you will be warned and can rectify the problem. Features such as wrong passing point positioning, bad bend radius or inappropriate dimension size of the section are likely to causes of these problems. This page provides information that will help you improve the creation of robust pathways.

If the pathway creation fails, the user is informed through a warning and a red curve in the pathway that the system has failed to create the pathway and decided to readapt the bend radius to generate a temporary solution. Then the user is asked to modify either the position of the points, the bend radius or section dimensions to correct the problem.

When the pathway generation succeeds, the pathway shape recovers its original color.

While creating the pathway, some limit cases are taken into account. The aim is to create a pathway even when such limit cases are encountered. You then have the option to modify the created pathway, as per your requirements, within the limits of the tool. Some of the identified limit cases are:

  • Section dimension
  • Bend Radius Ratio (too low / too high)
  • Too close passing points.

If the build of the curve fails at any point, the curve is displayed in red and a warning symbol appears at the first point of the curve where the build of curve fails.

A Pathway computation error message asks you to modify routing points, section dimension or bend radius value.

The curve remains red even if you exit the Create or Edit Pathway command. If you then revisit the same pathway with one of these commands, the warning symbol appears again (at the point where the build of the curve fails). Once the build of the curve is corrected, warnings will disappear.
