  1. OpenSCAD

3D CAD software tool for creating solid 3D CAD models, OpenSCAD is free and available to users of Linux / UNIX, Windows and Mac OS X. OpenSCAD focuses on CAD for creating 3D models and gives product engineers control over the modeling process because the tool is similar to a 3D compiler that reads script files and makes 3D models from files, not as an interactive modeler.

Basic functions:

  • Full control over the modeling process and easy change at every step in the modeling process
  • Provides two modeling techniques: structural solid geometry (CSG) and 2D contour extrusion
  • Reads and creates 3D models in STL and OFF formats in addition to DXF files

  1. VariCAD

VariCAD offers 3D / 2D CAD software for product engineers. With a comprehensive set of features, VariCAD is fast and easy to use to quickly create, evaluate and modify 3D models.

Basic functions:

  • Optional maintenance of parameters and geometric constraints
  • Modeling of shells, pipelines and wires
  • 3D joints and groups
  • Calculations of 3D objects or 2D sections
  • Uses STEP, STL, IGES, DWG and dXXF file formats for data exchange and fully supports Unicode
  • Provides tools for 2D updates after the 3D model changes
  • Provides a library of basic 3D shapes that are easily resized by editing their dimensions
  • Creates solid particles by rotating the profile, extruding or yielding
  • Sophisticated tools include mixing rotation between two profiles, uploading between a circle and a rectangle or between different profiles, and creating spiral surfaces

Price: VariCAD for Windows or Linux license + upgrade for one year: $ 520
