PickedTriangle() <- for selecting a polygon, PickedX(), PickedY(), PickedZ(), PickedEntity(), PickedSurface() will all help for selection, of course you will need to do a camerapick first.
drawing vertecies and lines:
Do a CameraProject() for every vertex, then draw an image for the vertex at the projected point with ProjectedX() and ProjectedY(). And to make the lines, use line() between the two points (you will have to temporaraly save the last location of a point).
