This method returns the object or objects in the FaceArray located at the given coordinates.

findAt initially uses the ACIS tolerance of 1E-6. As a result, findAt returns any face that is at the arbitrary point specified or at a distance of less than 1E-6 from the arbitrary point. If nothing is found, findAt uses the tolerance for imprecise geometry (applicable only for imprecise geometric entities). The arbitrary point must not be shared by a second face. If two faces intersect or coincide at the arbitrary point, findAt chooses the first face that it encounters, and you should not rely on the return value being consistent.

    findAt will always try to find objects among all the faces in the part or assembly instance and will not restrict itself to a subset even if the FaceArray represents such subset.

coordinates

    A sequence of Floats specifying the X-, Y-, and Z-coordinates of the object to find.

findAt returns either a Face object or a sequence of Face objects based on the type of input.

If coordinates is a sequence of Floats, findAt returns the Face object at that point.

If you omit the coordinates keyword argument, findAt accepts as arguments a sequence of pairs of sequences describing each face's coordinate and normal, and findAt returns a sequence of Face objects at the given locations. If you omit the coordinates keyword argument, you must also omit the normal argument.
