OpenSCAD is an open source programming language and IDE (Integrated Development Environment) for parametric 3D design. It is used to create precise, customizable and easily modifiable designs ready for 3D printing. It has a growing developer community and is the tool used to create designs compatible with the MakerBot Customizer app: http://www.thingiverse.com/apps/customizer
You can download OpenSCAD from www.openscad.org/downloads.html
This group is a place to discuss all things OpenSCAD including (but not limited to) new features, techniques, questions, libraries, works in progress, etc. So post a new Topic or contribute on an existing one!
Share knowledge, get constructive feedback, and ask questions!
Join to add your OpenSCAD designs or libraries to this group's Things. Non-OpenSCAD designs will be removed.
WOOT! now we can put comic sans on everything ;D
get it here: http://www.openscad.org/downloads.html
If you make any scripts that use features from the new version, add links to them in this post!

scale()behavior when using negative factors
polyhedron()now takes a
faces=argument rather than
assign()is no longer needed. Local variables can be created in any scope
In an effort to create my own thread library, I wrote a script to create a helix from any [[x,y],[x,y],[x,y],...] point array using polyhedron(). 3D points are generated in a helix about the Z axis. Faces to wrap each segment are defined, and cap faces are defined to close everything. Faces are clock-wise as per recommendation from OpenSCAD documentation. There is a definite inside and outside to the solid.
The thing looks pretty, until I attempt a union() or difference() action with it. Even exporting the helix alone to STL, and then importing it doesn't work. Importing it in to TurboCAD had limited success, I can do a 3D boolean addition(union()), but it breaks when I do a boolean subtraction.
Am I missing something?
So when I first installed openscad over a year ago, the positive scale showed with a solid line and scale markers, and it used to show me a dotted line and scale markers for negative numbers. Now, for negative numbers I only get the division numbers, but no dotted line or scale markers. I have been all over the view settings and preferences looking for it, but it's not there, unless I am missing it. Here is an example of what I see.
