Branch: CURRENT, Version: 2015.03p3nb3, Package name: openscad-2015.03p3nb3, Maintainer: reinoud

OpenSCAD is a software for creating solid 3D CAD objects. It is free software
and available for Linux/UNIX, MS Windows and Mac OS X.

Unlike most free software for creating 3D models (such as the famous
application Blender) it does not focus on the artistic aspects of 3D modelling
but instead on the CAD aspects. Thus it might be the application you are
looking for when you are planning to create 3D models of machine parts but
pretty sure is not what you are looking for when you are more interested in
creating computer-animated movies.

OpenSCAD is not an interactive modeller. Instead it is something like a
3D-compiler that reads in a script file that describes the object and renders
the 3D model from this script file (see examples below). This gives you (the
designer) full control over the modelling process and enables you to easily
change any step in the modelling process or make designes that are defined by
configurable parameters.

OpenSCAD provides two main modelling techniques: First there is constructive
solid geometry (aka CSG) and second there is extrusion of 2D outlines. As data
exchange format format for this 2D outlines Autocad DXF files are used. In
addition to 2D paths for extrusion it is also possible to read design
parametes from DXF files. Besides DXF files OpenSCAD can read and create 3D
models in the STL and OFF file formats.

  # OpenSCAD 2013.01

    **Features:**
    * Snappier GUI while performing CGAL computations (computations running in \ 
separate thread)
    * The size of the misc. caches can now be adjusted from Preferences
    * The limit for when to disable OpenCSG can now be adjusted from Preferences
    * Added Dot product operator: vec * vec
    * Added Matrix multiplication operator: vec * mat, mat * mat
    * Added search() function
    * Dependencies are now tracked - any changes in uses/included files will be \ 
detected and cause a recompile
    * The OPENSCADPATH environment variable is now implemented will have \ 
precedence when searching for libraries
    * .csg files can now be opened from the GUI
    * linear_extrude() will now assume that the first parameter means 'height' \ 
if it's a number

    **Bugfixes:**
    * use'ing an non-existing file sometimes crashed under Windows
    * Better font handling: Ensure a monospace font is chosen as default
    * Division by zero caused hang in some cases (e.g. sin(1/0))
    * Larger minkowski operations sometimes caused a crash after a CGAL assert \ 
was thrown
    * Fixed crashes in shared_ptr.hpp (or similar places) due bugs in cache \ 
management and CSG normalization
    * scale() with a scale factor of zero could cause a crash
    * Fixed a number of issues related to use/include
    * Providing an unknown parameter on the cmd-line caused a crash
    * cmd-line overrides using -D now also work for USEd modules
    * Modifier characters can now be used in front of if statements
    * rotate() with a vector argument with less that 3 elements used \ 
uninitialized variables, ending up being non-deterministic.
    * .csg files will now have relative filenames whenever possible
    * Don't just ignore geometric nodes having zero volume/area - when doing \ 
difference/intersection, they tend to turn negative objects into positive ones.
    * Always use utf-8 file encoding, also under Windows
    * A lot of build script fixes
    * Some other crash bugs fixes

    **Deprecations:**
    * The old include syntax "<filename.scad>" without the \ 
include keyword is no
      longer supported and will cause a syntax error.
