The DTDOT is an Isometric drawing tool with many attractive features to help create the perfect 3D design.
There is a pre-drawn isometric pattern on the tool that can be used to create drawing crates of any size by simply adding cubes and rectangles side by side.
There is a selection of ellipse tools that are places in such a way that you can't use the tool the wrong way up.
Some funky look arrows encourage good quality annotation and there is a special arrow to be used when adding a sustainability point to a design.
Finally the sun stencil, glasses and rendered cube all help the user identify a light source for their design in a hope they render it using three different tones.
