Have you tried changing Workplane from Z+ to Z- ?
Yep. Not working that way either. Anyway I got to make that pierced point today. It all depends on the direction of the scan not the direction of constructing the line. Instead of one big linear closed scan I broke it in two pieces one goes to the left another to the right. Works very well. Thanks for the help!
I don't think it would depend on the workplane, but it does depend on the vector of the line. Look closely at the IJK to see if you truly are reversing that direction...or construct a "reverse" line and then pierce the circle/cylinder with that new line.
I would :
Level Z, origin xy on the cylinder
Rotate Y+ on line (from cyl to ext)
Origin Z on line.
Then :
ASSIGN/ANGLE1=ACOS(LIN1.X/CYL1.R)
ASSIGN/INTERSECT_PT=CYL1.R*MPOINT(COS(ANGLE1),SIN(ANGLE1),0)
Then create a generic point.
