Geodrafter - Draw 2D Geometry easily
For each geometric shape enter one line of text. Available:
circle(x|y radius) circleseg(x|y radius startangle endangle) ellipse(x|y width length) line(x|y x|y) lineseg(x|y x|y) polygon(x|y x|y …) point(x|y "text") rectangle(x|y width length) text(x|y "text") star(x|y radius sides depth rotation) triangle(x|y x|y x|y) vector(x|y x|y)Add the # sign at the end of each line to hide the filling of the shape, for instance circle(0|6 2)#
