I will be given a part (a very complicated part ) next week, so I am programing on cad model the last two days. Since I can not get right alignment, I looked back, found a problem on plane vector. I got 8 points for datum A1, the vector is (0,0,1), got 8 points for datum A3 same vector (0,0,1). Since A1 and A3 had different on Z AXIS, I formed A3 points to be at same level with A1. I verified them, PLN_A1 and PLN_A3 vector still (0,0,1). That is common sense. But when I added all 16 points together, the vector changed, I attached the program.
Please help... Any command is welcome...
