I need to select a solid body in ANSYS Design Modeler, with script, in a design with multiples bodies. With the following command I select all the solid bodies, but this is not what I need.

ag.bodyPick;
ag.gui.SelectAll();

I'm creating a script to model two spur gears engaged, first creating one tooth then making circular pattern to create the entry gear, with the following script I create the pinion but when I'm going to make the circular pattern for the gear, the pattern command give me an error, because I select all the solid bodies including the pinion, and I need to pick only the solid of the gear tooth to make the circular pattern them.

This is my script:

ag.m.ClearAllErrors();
ag.gui.setUnits(ag.c.UnitMillimeter, ag.c.UnitDegree, ag.c.No);

var p = new Object();

//Plane
p.Plane  = agb.GetActivePlane();

p.Sk1 = p.Plane.NewSketch();
p.Sk1.Name = "Pinion";
p.Sk2 = p.Plane.NewSketch();
p.Sk2.Name = "Wheel";

//PINION

p.Sp1 = SplineBegin();

You can select a single body by this code:

agb.AddSelect(agc.TypeBody, bodyname);

Here is the script:

(Key ideas: First, assign name "GEAR" to the gear body ag.fm.Body(2).Name = "GEAR";. Second, creat gear object by gear = selectNode("GEAR"); where the function selectNode(target) is at the end. Third, use agb.AddSelect(agc.TypeBody, gear); after ag.bodyPick;)

ag.m.ClearAllErrors();
ag.gui.setUnits(ag.c.UnitMillimeter, ag.c.UnitDegree, ag.c.No);

var p = new Object();

//Plane
p.Plane  = agb.GetActivePlane();
p.Origin = p.Plane.GetOrigin();
p.XAxis  = p.Plane.GetXAxis();
p.YAxis  = p.Plane.GetYAxis();

p.Sk1 = p.Plane.NewSketch();
p.Sk1.Name = "Pinion";
p.Sk2 = p.Plane.NewSketch();
p.Sk2.Name = "Wheel";

//PINION
with (p.Sk1)
{
    p.Sp1 = SplineBegin();
    with(p.Sp1)
    {
        SplineFlexibility = agc.Yes;
