To resize a wall, simply select the wall then bring up the object info palette, you can then simply increase or reduce the length of the wall by which ever amount you wish by typing the desired length in or doing a + or - to the existing length.
Alternatively if you select the wall, position the cursor over one end, until a double ended diagonal arrow appears, click and drag the end of the wall, works with most 2d objects etc.
Openings can be inserted by using the wall opening tool and then adjusted to suit using the object info palette.
We like you much prefer the architectural ease of use of VW as it was our first stab at CAD and haven't looked back.
Hope this is of use
