35) Real-DRAW
Real-DRAW is a drawing application that combines vector, 2D, 3D and bitmap editing. Any object you create is always editable. You can change shapes, group objects, move them in layers, resize, edit envelopes and so on. You can paint directly onto any vector object using airbrushes, 3D or Artistic brushes and special Image Nozzles. You can paint on the canvas and the strokes will become another object to which you can apply effects, just as with vector objects. Real-DRAW works with Windows 95/98/NT/2000/XP.
