Hi Max,

> 1. Boolean Isect doesn't work with solid and line.

It seems to work over here but probably does not do what you need - the way the booleans work with curves interacting with solids is that the curve is extruded out into a surface and then it's that extrusion that interacts with the original solid.


> 2. Curve Isect generates many wrong points of intersections in some cases.

Can you post a 3DM file? I tried a box with diagonal line like you've got there and I got 2 points.
