Face centroid

[PawelSulikowski]

Hello.

I'm using NX7.5.3. I have body, that has mirrorplane. This means that I have two sets of corresponding faces (on the one side and "mirrored" side). Let's assume that the body is defeatured and those face are not planar (just 2 sets of body faces).
I need to match each face wfrom one set to it's corresponding mirroded copy. I thing the easiest way will be reading face centroid, mirroring the point and looking for face with centroid nearby (searching in second face set). I found that if user manually select a face and use Info -> Object it draws normal vector at centroid (It seems to me to be a face centroid. At least it seems to be characteristic enough for me.)
Question:
Is there a way to get this information using VB Journal script? Or any other methon to get face characteristic point or centroid?

Do you have only the 2 bodies, or do you also have the mirror plane to work with (a datum plane or other planar object)?

Lets say it is one body + mirror plane.

Originally, you wanted to find corresponding faces in the mirror body copy.

What do you want to do with the one body and mirror plane?

I originally wanted to match faces from one side of the body with corresponding faces on the other side.

Anyway i managed to solve this by searching for mirrored copy of face center. I calculated the center using this code:

Dim theScalar As Scalar = workPart.Scalars.CreateScalar(0.5, Scalar.DimensionalityType.None, SmartObject.UpdateOption.AfterModeling)
Dim thePoint As Point = workPart.Points.CreatePoint(targetFace, theScalar , theScalar , SmartObject.UpdateOption.AfterModeling)
return thePoint.Coordinates

So...
problem solved?

Not the way I wanted to solve it, but yes, solved.
