Troubleshooting Guide
Problems:
- Triangulation appears to cross-over internally
- End plates are not created
- Triangulation has holes in it
- Tie lines not followed
Triangulation appears to cross-over internally
-
Ensure that the strings are all the same direction ( Analyse > Label > Point Label to Text option). Any strings in the wrong direction can be reversed using the Design > Object Edit > Reverse or Design > Object Edit > Consistent options.
-
Check for duplicate points ( Analyse > Label > Point Label to Text option). Make sure there are no two points at one location. Use the Design > Point Edit > Delete Duplicate option or the Design > Object Edit > Filter option to remove excess points.
-
Ensure that the string does not have local loops in it, i.e. the string should maintain its sequence without local cross-overs in the string.
-
Ensure that any tie lines used are snapped to points.
-
Try 'User guided' rather than Optimal creation of the triangulation. Use this only as a last resort.
-
The check for crossing triangulation/trification will also display problem areas in a triangulation (angular strings with few points between angles are prone to cross overs).
End plates are not created
-
Ensure that the end plate box in the panel has been checked.
-
Ensure that the end object does not crossover itself in this plane. This may occur when making solid triangulations of underground roadways, for example a decline. This problem is overcome by breaking the object up into a series of objects that do not cross or locally loop in the one plane.
Triangulation has holes in it
-
Ensure that the tie lines do not come to a coincident point.
-
Ensure that all objects are closed.
Tie lines not followed
-
Ensure that the tie-lines box in the panel has been checked.
-
Ensure that the pick aperture is set such that the tie-points and the string points are in the pick aperture dimension. The pick aperture dimension is set through the Graphics : Input section of the Tools > Preferences option.
