GuiTSCtrl::unproject

I would like some assistance in understanding this function. After searching, and fiddling for the past few days, I have not reached my desired result.
I have created a custom gui control which inherits from GuiTSCtrl. In this control I render client side only objects. My goal is to have a rendering window for editing objects' sizes, shapes, etc. that will be only client side and very light weight.
I would simply like to know how to get the 3D position of a click on a 2D control. After looking into EditTSCtrl::make3DMouseEvent and the subsequent call to GuiTSCtrl::unproject, I have found that it produces a normalized Point3F and not the actual position. I thought maybe I could multiply that Point3F by the camera's FOV along with the controls extents, but the numbers are still off. Any advice or even a point in the right direction would be highly appreciated.

Although object Selection is not what I needed, it gave me an idea of the code I needed to write. Again, I appreciate the point in the right direction. A video of my non-sim/scene object creation and selection in the custom GUI control.
