Hi,

I am having some tolerance issues when measuring between points/ vertices and I wonder what the reason for it is. It seems like there is a discrepancy measuring between Point3f which is used internally for Mesh Vertices and Point3d. Please see attached screenshot as an example.

I am working on a facade and try to determine repetition of panels by comparing quadfaces of meshes. I measure for this all 4 sides of a quadface + the 2 diagonals to determine congruence. From measuring between the Point3f I get different results then from measuring my initial setout points. The error occurs at the 4th decimal - as I then round to the 3rd decimal it does affect my endresult.

Is this a problem of double vs. floats precision ?

By the way my doc. tolerance is 0.001

Many thanks,

Philipp
