I have written an Instructable with some more advanced topics. I think it will have more value to members of this forum than my introductory one. http://www.instructables.com/id/Openscad-Saving-STLs/ <http://www.instructables.com/id/Openscad-Saving-STLs/> It shows techniques for recreating a bad STL. Some of the techniques are useful for general OpenSCAD design.

Steve: Wow! I had no idea you could do what you did, so this is very important to me! Not sure I have as much patience as you did. How long do you think it would take you to make the anvil if you were not documenting the process along the way?

Jon, It would take maybe an hour. I already have the hull_shape and pointer modules written. I use hull_shape a lot when I have an STL to use for a frame work. When you can find the limits of an arbitrary shape with the pointer, then the hull_shape makes it easy. And it is easy to union separate sections together. I didn't have a spot to show this with the anvil, but you can use the same locations for the joining part (a plane typically) for two hull_shapes and use spheres of slightly different sizes. The join will be manifold. Steve -- View this message in context: http://forum.openscad.org/Advanced-OpenSCAD-Instructable-tp13389p13393.html Sent from the OpenSCAD mailing list archive at Nabble.com.
