If there's something that makes Creative Docs stand out and that makes it different from Inkscape, it's for using a completely new drawing system, much simpler and easier to learn.
Creative Docs includes an important number of predefined forms, among them are: square, triangle, circle, ellipse, free hand or Bezier curve, polygon, 2D and 3D figures, etc. It's also possible to include text in lines or in a text box.
Additionally, it has never before been this easy to add the dimensions of an object thanks to the intuitive limitation system included in the program. Try it, it won't let you down!
