Error 2232 - For z-shapes

Recommended Posts


I'm adding proposed ground elevations to an existing model, which require sensitive adjustments to fine tune the design. Occasionally I will get the message Error 2232... triangulation failed.... check region does not intersect or snap onto itself.

I will have only moved one TIN line slightly, nothing which I would have thought would cause this error. If I then move the TIN line again slightly, it may run ok. The error seems to be quite random!

Any possible reasons why this would occur?

Hi Richard

Can you please see if the build uploaded last night (2008-08-AH) causes this to occur as coincident points on the region's perimeter can cause this, and this bug has been fixed in 2008-08-AH. Otherwise the only known reason this can occur is if the region snaps back onto itself or overlaps (ie. the perimeter crosses itself as in a figure of 8).

If the problem persists, can you please email to support@tuflow.com the .tcf, .tgc, any 2d_loc.mif/mid layer and the mif/mid files for the layer in question.
