Get 3D coordinate from a 2D sketch

I have a 2D sketch on a plane. The plane is not coincident with the front plane. The plane is parallel to the front plane. I am using the code below to get coordinates from the points in the plane. Two questions:


  1. When I use the code below I get a value for a point as
    x: 2.5234
    y: 1.2154
    z: 0
    Z is always zero even though the plane is at 0.050 meters from the front plane. I expect the Z to return 0.05. Solidworks is obviously doing some kind of 2D math and then transforming the 2D sketch into 3D space to get the x/y/z coordinate? How do I get the actual 3D coordinate rather than a 2D coordinate?
  2. I am only after the points. When I say points I mean the sketch entity that is called a point. I currently get the center of a circle as well. How would I filter a sketch point?



ISketch sketch = (ISketch)feature.GetSpecificFeature2();
object[] points = (object[])sketch.GetSketchPoints2();
foreach (ISketchPoint point in points)
    Point3D pt = new Point3D(point.X, point.Y, point.Z); //<--Point.Z is always zero.
