I would like to use .stl files (created in OpenSCAD) in other projects, however while I can import I can't get the .stl object to compile and render in GCAL. I'm using the latest Windows build (OpenSCAD-2011.11.01-Installer.exe) and to read the .stl file I use the import command:
import ('foo.stl', convexity = 4);
I can then preview this (with an F5 compile) and see the object. With the same command when I try the F6 'compile and render in GCAL' option I receive the following warning message:
Parsing design (AST generation)..
Compiling design (CSG Tree generation)..
Compilation finished.
Rendering Polygon Mesh using CGAL..
PolySets in cache: 3
Polygons in cache: 41406
CGAL Polyhedrons in cache: 5
Vertices in cache: 24
Total rendering time: 0 hours, 0 minutes, 0 seconds
WARNING: No top level geometry to render
I guess there is some additional syntax needed, but I can't figure out what it should be. All help appreciated!
Cheers,
Ian

OpenScad beginners tutorial at EduTechWiki. Mar 2010 - May 2012. OpenSCAD works in a different way compared to the expensive commercial software packages typically used for 3D design. Instead of interactively choosing from a multitude of obscure, hard to remember icons, buttons, menus, and sub-feature options to sketch out your designs with a mouse, OpenSCAD lets you edit a text-based script that creates.
Lithophane program. Quadcopters are fantastical things, and now come in a huge variety of flavours, from lithe featherweight racers to industrial-grade filming rigs worth tens of thousands of dollars. The Beatle-1 from [masterdezign] comes in at the smaller scale, and its body was created entirely in code.
- OpenSCAD is a free CAD software for creating solid 3D models. Unlike most free 3D modeling software, it doesn’t focus on the artistic aspects of 3D modeling but instead on the CAD aspects. OpenSCAD works like a 3D-compiler that reads in a script file that describes the object and renders the 3D model from the script file.
- OpenSCAD is great at making parametric designs — models represented by numbers that can be easily adjusted to change the size, shape, or any other aspect of a design.
Jun 05, 2020 The CSG (Constructive Solid Geometry) used by OpenSCAD, draw circular and spherical objects using line segments and as a result faces. The$fn determines how many line segments are used, as a result the $fn arguement can be used in multiple ways. The first is create smoother arcs and spherical surfaces.
To create the Beatle-1, [masterdezign] used OpenSCAD, a 3D modelling program that uses code rather than visual tools for producing geometry. Thus, with a series of Boolean operations, extrusions and rotations, a basic lightweight quadcopter frame is created in a handful of lines of text. Then, it’s just a simple job of 3D printing the parts, wiring up four Olimex F1607 motors and hooking up a flight controller and the little drone is ready for takeoff.

Th8 base trophy. The Beatle-1 serves as not only a fun flying toy but also a great example of applying OpenSCAD modelling techniques to real-world applications. Parts are available on Thingiverse for those wishing to roll their own. 3D printed drone frames are popular, and we’ve seen a few around these parts before. Video after the break.
