In addition to 2D paths for extrusion it is also possible to read design parameters from DXF files. SVG is used for 2D while Autocad DXF files can be used as well for the data exchange format for 2D outlines. extrusion of 2D primitives into 3D space.OpenSCAD provides two types of 3D modelling: It is not an approximation and as such it is often a lengthy process, taking minutes or hours for larger designs. Render generates exact geometry and a fully tessellated mesh. Preview is relatively fast using 3D graphics and the computer's GPU, but is an approximation of the model and can produce artifacts Preview uses OpenCSG and OpenGL. OpenSCAD has two main operating modes, Preview and Render. This enables you to easily change any step in the modelling process and make designs that are defined by configurable parameters. This gives you (the designer) full control over the modelling process. Instead it is something like a 2D/3D-compiler that reads in a program file that describes the object and renders the model from this file. OpenSCAD, unlike many CAD products, is not an interactive modeler. So it might be the application you are looking for when you are planning to create 3D models of machine parts, but probably is not what you are looking for when you are more interested in creating computer-animated movies or organic life-like models. Unlike most free software for creating 3D models (such as the well-known application Blender), OpenSCAD does not focus on the artistic aspects of 3D modelling, but instead focuses on the CAD aspects.
