    I'm a new user of autocad. and I will use it only to design very simple
    mechanical drawings

    so my questions is better illustrated iwth a simple example
    I create a square of 10 inches edge. I draw two circlels in it.

    now I extrude the square to a cube (10x10x10). then I want to have the
    circles to become holes one starting from the bottom surface and
    entering the cube for 1 inch. and the other hole starting from the top
    surface and entering for exmaple 2 inches into the cube.

    My problem is that all the elements are on the bottom surface and when
    I extrude I always extrude starting from the bottom. is there a way to
    have one element positioned on the top and extrude from there negative?
    I would like to find a way to make this more convenient than moving the
    object physically with the mouse.

    hope I was clear enough

    Change the Elevation property for the circle that will become the upper
    cylinder. You can also draw objects at any elevation you desire by simply
    setting the default Elevation before creating them. You can find lots of
    good information in HELP by pressing F1 and doing a bit of searching.

    thanks the elev is very helpful and immediately helped me out for the
    now other question related
    I made different objects at different elevations.
    let say now I changed my mind regardign an object. is it possible to
    change its value of elevation to another one with a command?

    Yes, with the CHANGE command. Or with the PROPERTIES dialog.

    Oh boy. The general advisory attitude of the group is appreciated but using
    the F1 button should be more strongly suggested. Like during the former
    Chinese cultural revolution every unliterated peasant was entitled to attend
    any university faculty for education (high school studies beginning with
    primary school mathemathics like (1+1=2)).

    Sorry for my bad english

    Draw the second circle on the top surface, set the UCS accordingly and
    extrude down. Learn about UCS it is very important in solid modelling and 3D
