Moving an object's center node

I am having a hard time selecting a center node and moving it from it's default position.

I am making an arc shaped label with degree marks.  I draw the the first mark using a rectangle.  the rectangle has a default center node.  I will use the Transform > Rotate to make a more degree marks.  To do that I want to move the center node of the rectangle to the center of the arc.  I am having a hard time grabbing the center node to move it to where I want.   I've done it before and I assume there is some sequence of selection clicks on the node that allows it to be moved.

  • You might already know this, but I'm not completely sure what you mean when you write, "center node", so...

    There is a Center for the shape, but that's not what you want to move. You want to move the center of rotation.

    The center of rotation (circle with a dot in the center) is visible when the shape is in rotate/skew mode.
