Welcome!

by atartanian

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.

Have fun!

Pro-Tip: Fix the axes of imported objects w/ your slicer.

by jetdillo

I've found it much easier to fix off-centered axes of imported objects by first loading the object in question into my slicer, clicking on "Center on Platform" and then re-exporting the object back out.
Now do your import("/some/path/to/my/object/foo.stl") and it will show up right at origin in OpenSCAD.

This works for me in Cura and Ideamaker and is much simpler than having to remember how to do it across Fusion,OnShape,Meshlab, etc.

Do fast PCs render faster?

by Skybound420

I've had this junk Gateway laptop running since 2012 so I am well past due to treat myself to a new machine, but it still does what I need it to do. As of recently, I've been doing a lot of designing and printing prototypes, and I only design with OpenSCAD because point and click apps kinda freak me out, lol. Some of my SCAD designs take a long time to render and I was wondering if a newer PC with a faster processor will render quicker? Are there any cheap end PCs I should shop for?
