Hi, everyone, i need the get the intersect points of a line and a complex shape like a staircase, the hit points can more than two. i use the function BRepAlgoAPI_Common but in some case the result is not correct. it looks like i only can get two points in the result or some other reasons, can anyone help me? maybe it's come problem of tolerance setting or BRepAlgoAPI_Common function setting? thx here!
