GizmoGraph

GizmoGraph is a 2D vector drawing application. With GizmoGraph you can create points, segments (with text and/or picture), circles, ellipses, curves, plolygons, and polycurves.

Most interesting, you can define geometrical constraints between these objects like drawing a parallel or a perpendicular from a point to a segment, intersections between these objets, and much more.

Your drawing may be built of many layers (for example, with the purpose of separating text from geometrical objects). You also may add a background (colored, picture or a pattern). The drawing can be saved as a metafile (for modifying your work) or as a picture (.jpg or .png with alpha layer).
