Hello, can anyone help on how to align a cylindrical part with no rotation? I attached an image of the model. The flats on the model aren’t machined yet. I created two circles and then constructed a 3d line between the circles and created a point on the plane. I then leveled to the line, then set the x and z origins to that same line. The i set my Y origin to the point. I ran it once and then set up a new part and my whole alignment was thrown off. Did I do something wrong? Is there a better way of doing this? Hopefully I can get some advice for next time I have to do this.
I have to ask, when you say "I ran it once and then set up a new part and my whole alignment was thrown off", how do you know it is off? If there is no clocking, what are you comparing to? What did it do the 2nd time that you considered so different from the first time?
JacobCheverie is not wrong. If there is no clocking feature then the best you can do is to lock the rotation with something else such as the machine coordinate system X or Y axis. This would constrain all 6 degrees of freedom. However, even if you remove the part and then randomly put it back, there is no real way to identify any question dimension such as roundness. It should report the same value but you would not know where the high and low points are.
