Annotation of mystuff-openscad/cad/openscad/pkg/DESCR, Revision 1.1.1.1

1.1       afresh1     1: OpenSCAD is software for creating solid 3D CAD models. It is free
                      2: software and available for Linux/UNIX, Windows and Mac OS X. Unlike
                      3: most free software for creating 3D models (such as Blender) it does
                      4: not focus on the artistic aspects of 3D modelling but instead on
                      5: the CAD aspects. Thus it might be the application you are looking
                      6: for when you are planning to create 3D models of machine parts but
                      7: pretty sure is not what you are looking for when you are more
                      8: interested in creating computer-animated movies.
                      9:
                     10: OpenSCAD is not an interactive modeller. Instead it is something
                     11: like a 3D-compiler that reads in a script file that describes the
                     12: object and renders the 3D model from this script file. This gives
                     13: you (the designer) full control over the modelling process and
                     14: enables you to easily change any step in the modelling process or
                     15: make designs that are defined by configurable parameters.
                     16:
                     17: OpenSCAD provides two main modelling techniques: First there is
                     18: constructive solid geometry (aka CSG) and second there is extrusion
                     19: of 2D outlines. Autocad DXF files can be used as the data exchange
                     20: format for such 2D outlines. In addition to 2D paths for extrusion
                     21: it is also possible to read design parameters from DXF files. Besides
                     22: DXF files OpenSCAD can read and create 3D models in the STL and OFF
                     23: file formats.
