Exception "Span has no thickness"

[AqlaSolutions]

height = 5 span.Minimum = 5 span.Maximum = 6 After clamping minimum=maximum=5

    Cell.AddSpan(Span span):
        //clamp the span to the cell's range of [0, maxHeight]
        MathHelper.Clamp(ref span.Minimum, 0, height);
        MathHelper.Clamp(ref span.Maximum, 0, height);

        if (span.Minimum == span.Maximum)
            throw new ArgumentException("Span has no thickness.");
        else if (span.Maximum < span.Minimum)
            throw new ArgumentException("Span is inverted. Maximum is less than minimum.");

Any workarounds?

Sounds like an edge case. Thanks for including an .obj file, will investigate.

[Robmaister]

Yeah, so the bounding box I generate for a level is exactly the size of the level, and when you have a triangle exactly at the upper bound, it will think it's one voxel above the specified size. I'll fix this in a minute.

Provided .obj file can now be run through the Examples project without any problems. Thanks for finding this bug!
