Not really sure what you are on about but....
Whatever the profile of your shape is, in say left window make it our of vertexes in the same plane.
Then select all your vertexes and move them with SHFT + RIght click a small amount.
Then go to the top window and rotate your new vertexes the desired amount. Repeat until you have the shape you require.
If you want to create a non regular shape then you are stuck moving individual vertexes from a standard shape.
OR
Select the vertexes/ faces you have made and press I to make the surfaces smooth, this will make your shape less blockly.
