4.1. The Guitar

Choose the Create Slab Tool and draw the shape below in the front view - taking care to stay one side of the centre line.

Next turn on Symmetry in the Object Properties.

If you want to move or rotate a Symmetrical slab you must first 'bake' the curve driven object into a simple mesh. Just press 'K' to convert.

While this means you lose access to the control curve, you can now freely move and distort the object.
