I'm using the custom transformer "slope calculator", developped by Safe and which can be downloaded at http://fmestore.safe.com/transformers/SlopeCalculator.htm
It happens from time to time that one of the triangles produced in the slope calculator is so small that the _nz and _length values are null, thus producing a fatal error (attribute_creator_6 is traying to make a division through zero...).
We managed to overcome this limitation by testing the "sloped" area of the produced triangle and adding a tester passing features having an area > 0.000001. This does not alter much the transformer as, at the end, it uses the average slope value.
I think it would be really good to have something like that by default in this custom transformer... or am I completely wrong ?
If yes, is there a way to contribute ?
Best regards
Michael
