Also, all the google fonts from http://www.google.com/fonts have been added to the servers and can be used in text() :)

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!

How to Model a Solomonic Column

by aelfric5578

I've seen a number of different solutions for helixes around. Has anyone tried modeling a Solomonic column in OpenSCAD (example from Wikipedia attached). I'd like to use this kind of shape in something but I'm still a relative beginner with modeling and not quite sure where to start. Thanks in advance.

Seeing some cylinders show strangely in Customizer vs OpenSCAD

by jcoehoorn

I'm playing with rendering some Lego pieces, and, while I still have some work to do, I have things generally working in OpenSCAD.

However, when I view a piece rendered by the Customizer the studs are skinny. In fact, I download a Customizer STL, measure a stud (using 3 different tools, including Meshmixer), and the studs are only 2 mm in diameter (1.99+). The same option, rendered directly in OpenSCAD, using the scad file downloaded back from my Thingiverse thing (not the original), creates studs that are 4.8 mm diameter.

What's going on here?

Here's the thing:


And here's reduced code used to rendering a single stud:

LU = 1.6; 
stud_radius_adjustment = -.02;
base_stud_height = 1.8;
stud_height_adjustment = .1;

stud_height = base_stud_height - stud_height_adjustment;
stud_rad = (1.5*LU) - stud_radius_adjustment;

cylinder(stud_height,stud_rad, stud_rad, $fn=40);

I'm using OpenSCAD 2015.03, which should be the same version used in Customizer.
