I would be grateful if anyone could help.Sounds like you could simply use the paint tools and an image object overlaying whatever you want to draw on. See the docs under choosing tools ("choose" command) and: - pencil - brush - spray can - bucket Alternatively, you could use draw graphics, using the curve tool for free-form drawing, or primitive shapes and polygons, but this can create multiple objects, depending on how you implement it. Hopefully there's something here you can use. Regards, Scott Rossi Creative Director Tactile Media, Multimedia & Design
Robert,
Just to add a bit to Scott's good advice:
If you would like some tools to facilitate this kind of drawing, the ideal is Turtle Graphics. You can control the turtle (drawing cursor) with such simple commands as:
Relative tools (independent of a coordinate system): Forward,Back, Left, Right, setHeading, etc.
Absolute tools (coordinate based): setXY, incrementXY, xyCoordinates(), xCor() etc. .
The good people at RR have posted a demo stack in the "Education" page on the RunRev site:

Check the User Contributions. This is intended primarily for an elementary course in programing in Transcript and Turtle Graphics for science students, but it may also work for you.
