Polar Points, Vectors and Variables

ELaFever2
Hey gurus,

I must measure impeller blades (9) and have been given a chart of X, Y, Z locations for points. The chart is only for the points on one blade. In my code below I have an example of how I am maintaining the nominals and expanding the points to the other blades.

What I am having a problem with is having the I, J, K vectors adjust along the same lines as X, Y, Z. Can anyone help me figure this out?
Or let me know of another way?

  • 1) I do not like your variable names. It has been said NOT to start with a number, start with a letter, and you are using things the software recognizes (X, Y, J, PA) which seems to me like you are begging pcdmis to evaluate some Polar Radius in there. I use the letters, sure, but my variables are combinations of letters that would never be mistaken by PCDmis. The second half, is just me, do what you want, but don't start with a number.

    2) are you trying to do this in a loop? If not, the variables are a waste of your time.

    2.5) Is there a reason you don't key the points in on one vein and copy then Paste With Pattern? A reason other than you don't know what that is.

    2.5.5) If you just don't know how, put the points on one vein. Set the center of the pattern as 0,0 and workplane looking down on the patter. Right click copy the stuff. On the edit menu, select Pattern and set the rotation with the number of times. Then on the Edit menu, select Paste With Pattern.

    4) if you are looping, you need your I, J and K to be variables, which you only did on A_1T, B_1T and on is just numbers.

    4.5) If you are asking how to convert the I, J and K to variables, I'm going to question what you did above, where you have an I, J and K all non-zero, meaning you are moving in three axes, but you are only using X and Y in your PR and PA calculations. If it is a 3 axis move, you need to evaluating on all three axes.
