CAD program/s with plain-text scripting language

[Vigardo]

Hi experts,

What CAD program/s include a plain-text scripting language? Any free?

I´m looking for something similar to Ansys´ APDL, but intended to perform boolean operations with simple geometrical shapes (spheres, boxes, cylinders, etc.) and able to generate meshed objects in STL or other 3D printing amenable format.

Thanks a lot!

While I don't know of a program that fits your requirements, many CAD editors do support SVG which can be manipulated in a web page with javascript.

One example is Inkscape.

SVG is described here:

Thanks Jedishrfu for your contribution, but SVG seems only designed for 2D graphics.

After searching deeper, I´ve found that the Python-based scripting lengauge provided by FreeCAD would fulfill my requirements, i.e. easy basic shapes generation, boolean operations, and STL export capabilities. Here is the link to the "part scripting" page: http://www.freecadweb.org/wiki/index.php?title=Topological_data_scripting

Any other alternative?

How about this?

generates 3D SVG

It seems that SVG format is also capable of 3D. It is interesting, but I can't see if 3DTin has some scripting language to create and export models into STL. By the way, I don't want online tools because I need to automate the STL files generation using some local in-house Perl script. Thanks!
