How to find a face based on its (xyz) location and make it into a named selection by script in SCDM?

Erik Kostson

We want to search an area in 3D space (based on x,y,z coordinates and a tolerance that makes the 3D search space a volume), and find any face(s) (centroid(s)) of a part(s) within this search volume. Finally if a face is found make it into a named selection by script in SCDM.

import math
def locfindface(xx,yy,zz,tol):
    bodies = GetRootPart().GetAllBodies()
    for b in bodies:
        faces = b.Faces
        for f in faces:
            faceSelection=FaceSelection.Empty()
            faceSelection = FaceSelection.Create(f)
            e=MeasureHelper.GetCentroid((faceSelection))
            tolz=1
            toly=1
            tolx=1
            tolz=math.copysign(tolx,e[2])*tol
            toly=math.copysign(tolx,e[1])*tol
            tolx=math.copysign(tolx,e[0])*tol
            if (xx-xx*tolx<=e[0]<=xx+xx*tolx) and (yy-yy*toly<=e[1]<=yy+yy*toly) and (zz-zz*tolz<=e[2]<=zz+zz*tolz):
                secondarySelection = Selection.Empty()
                ns = NamedSelection.Create(faceSelection,secondarySelection)

locfindface(0.24, 0.0025, -0.031,0.08) # call the above function
