Determines the intersection point between two lines (p1,p2) and (p3,p4). Get answers fast from Autodesk support staff and product experts in the forums. Set the Start Z and End Z values to 0 (if these show up as 'varies', then you'll see why AutoCAD is complaining about non-coplanar lines). ilp(p1,p2,p3,p4,p5) Determines the intersection point between a line (p1,p2) and a plane passing through three points (p3,p4,p5) The ill and ilp functions determine intersection points. The view below shows a nut, bolt and a line, the requirement is to rotate the nut and bolt to the exact angle of the line. There is one intersection point and the lines are around it. Autodesk is a leader in 3D design, engineering and entertainment software. The only requirement for the objects we are going to break is to have the same Z value. No intersection. Form Autocad 2000 to 2012, there is always with this problem. Share a link to this answer. The user first picks the three points on the plane, then picks two points on the line in AutoCAD.
