Irricad

This situation may only occur if polylines are converted to individual tapes or spraylines that are not part of an irrigation block (that is, not created via the Irrigation block tools).

When there is a double-point at the same location (a zero-length segment) in a tape or sprayline then the new management symbol option for graphical management causes a crash.

The issue will be rectified in the next IRRICAD Standalone Version 20 patch.

In v20.06 the crash can be stopped by turning off “UsePolylineBlocks" option in the registry.
1. Run REGEDIT.
2. Browse to Computer\HKEY_CURRENT_USER\Software\AEI Software\Irricad\VisualSettings\Hydraulic.
3. Locate the “UsePolylineBlocks" string in the right-hand pane.
4. Double-click on the "ab" symbol to the left of the string name and change the Value ‘1’ to ‘0’ as below.
Alternatively, use Design|Other Management Options|Assign System Flows to Zones until the patch is released.

This issue has now been resolved in V20.07.
If you had changed your registry settings to avoid this issue then you can now set it back to the original settings if you wish to use the "Polyline Blocks" option.

1. With IRRICAD closed run REGEDIT.
2. Browse to Computer\HKEY_CURRENT_USER\Software\AEI Software\Irricad\VisualSettings\Hydraulic.
3. Locate the “UsePolylineBlocks" string in the right-hand pane.
4. Double-click on the "ab" symbol to the left of the string name and change the Value ‘0’ to ‘1’.
