Creating a Query from a Plane

Hi,

I have the following code:

var horizontalPartSketchPlane = evFaceTangentPlane(context, {
"face" : face,
"parameter" : vector(0.5, 0.5)
});

var skHorizontalPart = newSketch(context, id + faceIndex + "skHorizontalPart", {
"sketchPlane" : horizontalPartSketchPlane as Query
});

Which fails at the sketchPlane attribute.

What's the correct way to convert the plane entity to a query please?

Thank you.
