Do changing Target Pts "move" the probe along a surface?

NeverSayNever
I'm having problems understanding the code below.

My first question is this: By changing the TARG "X" values for each subsequent vector point, is this, in effect, moving the probe along the surface in the X direction? That is, does this code take actual hits in different locations? Even though the THEO values are EXACTLY the same? This part of the program is attempting to measure the D.O. between two vanes.

My second question: If this is indeed "scanning" along the surface, I'm wondering why this approach is advantageous over , say, just changing the THEO value from point to point.

First post. Appreciate any insight.

  • Wait a second. Is the point taken for each TARG hit being projected back to the THEO surface normal vector? That would explain WHY all my ACTL "X" values are the same. the ACTL "Y" and "Z" values differ, but the "X" values are all the same.

    Problem is, when I take these ACTL XYZ coordinates and plot them out in UG, it "looks" like all the points are right on top of each other.

    Is that what TARG is doing? Projecting back to THEO? If so, can that be turned off, so my ACTUAL XYZs are REALLY the actual XYZs?
