Tony,
You must have the "Generative Shape Design" or "Wireframe and Surface Design" modules. LMB on Start, and hopefully you will see those choices. Activate one of them and then you will see a "point" icon.
Not all businesses purchase all the needed modules.
you could use power commands. If you have a CATIA P2 configuration you will see a white box bottom right of your screen. If you type coint you can type 10,10,10 which will give a point at theses co-ordinates
