Tools on Surface is a Suite of Tools drawing on curved surfaces, with lines, various shapes, offset and Freehand / Polyline. It provides an inference mechanism, a Contour Editor and a dedicated Eraser.

Shapes includes:
- Circle and Polygon
- Rectangle, defined by its length and width
- Parallelogram, defined by its length, width and angle
- Ellipses, defined by axes
- Circle defined by 3 points
- Arcs(circular)
- Sectors, defined by origin, direction and angle
All shapes have in addition the option to draw Rings, that is, the same contour offset by a negative or positive distance. And of course, all generated contours can be later edited by the Contour Edition tool.
The inference mechanism tries to simulate some stickiness when lines are drawn along some remarkable directions. There is also a Lock inference mechanism to force drawing in a particular direction. A Protractor can help to pick particular angles.
ToolsOnSurface also works to draw lines and shapes 'without' a surface.
