I use Turbocad pro 11.2, but without the cam package. The cam side is still only 2D or 2.5D, so it won't like doing what you are trying to do. The pro version does draw 3D pretty well though. A little higher learning curve on the 3D side of the tools, but if I did it, you can too.
About the easiest way to do this other than probing or laser scan it to scan it in as a bmp, then just redraw over the top of it. If it is mostly straight geometry and text, then you should have little trouble with it. Once you have a simple line drawing, you could even use a 2D program like Sheetcam or many others to pocket or cut around your objects to a depth that you wanted.
You can also take a picture of it or a scan and import into a graphic program (I use Corel Draw and Photo Impact.) You will have to play around with blurring and shading, but then you can import into Meshcam and it would cut a likeness of it. May be good enough for what you want. That goes faster than redrawing, but you don't have as much control over the finished drawing.
Why don't you load the image you have here? We could then see what obstacles you might face.
