I’m new in Catia c#. I didn’t find a source or solution for boolean operations in Catia.

I wanted to create some bodies after that using boolean operations on those bodies.

private void button3_Click(object sender, EventArgs e)
{
    PartDocument partDoc = (PartDocument)myCATIA.ActiveDocument;
    Part part = partDoc.Part;

    Body body1 = part.Bodies.Add();
    Body body2 = part.Bodies.Add();
    Body body3 = part.Bodies.Add();

    body1.set_Name("A");
    body2.set_Name("B");
    body3.set_Name("C");


}

With a button I can create bodies and names but I didn’t figure it out how to use add remove in the code.

So basically I just wanted like this in my tree:
