Hi All,
Does anyone know why the contour command is not 100% reliable?
In the attached file with a spacing of 500 there is a contour line not being extended through full width.

Hello- it looks like that contour grazes a knotline-
I’ll add a bug report for that,
RH-75445 Contour - misses near knotline
but… the surface is a bit messy and over defined-
I’d try to make this much more simply.

Thanks Pascal for reporting this bug.
I am aware that the surface is not the best but since it has been provided by another user I have to live with it anyhow 
and I suppose that the contour command shouldn’t be interrupted irrespectively of the quality of the surface (as far as practicable ofcourse)
