With Creo Parametric, and its extensions, you can create, analyze, view, and share designs downstream using 2D CAD, 3D CAD, and parametric and direct modeling capabilities.




NaroCAD is described as 'The goal of this project is to develop a fully fledged and extensible 3D CAD software based on the concept of parametric modeling of solids, comparable to well known solutions' and is a CAD software in the photos & graphics category. There are more than 50 alternatives to NaroCAD for a variety of platforms, including Windows, Mac, Linux, Web-based and BSD apps. The best NaroCAD alternative is FreeCAD, which is both free and Open Source. Other great apps like NaroCAD are SketchUp, LibreCAD, Autodesk AutoCAD and OpenSCAD.

JSketcher is the most popular Self-Hosted alternative to NaroCAD.
Feature-rich 2D and 3D CAD application supporting native DWG files, offering multiple-document interface, advanced drafting tools, full AutoLISP and ADS compatibility, IntelliCAD Explorer for managing layers and settings, seamless Windows integration, and support for legacy drawing formats.




Asset Forge allows anyone to create 3D models and 2D sprites using building blocks. Finished assets are compatible with most available game engines.




MakerSCAD is a web-based parametric 3D design software with a block-based programming language to create objects for 3D printing, animations, games and websites.



DesignSpark Mechanical is a 3D modeling software reported to be easy to use so that all engineers will be able to create and share models.




nanoCAD is a pro-grade 2D CAD system with native DWG support and full customizability. It is totally free, for business, professional, or personal purposes. It is fast, lightweight, capable, and , unlike most free CAD programs, completely uncrippled. nanoCAD includes:


SALOME can be used as standalone application for generation of CAD models, their preparation for numerical calculations and post-processing of the calculation results. SALOME can also be used as a platform for integration of the external third-party numerical codes to produce a...



SpaceClaim Engineer is the world’s fastest and most innovative 3D direct modeler. SpaceClaim Engineer brings 3D solid modeling to the desktops of engineers and analysts who work in 3D, with a simplicity and low TCO (Total Cost of Ownership) never seen before in CAD.


KOMPAS-3D is for creating three-dimensional associative models for individual parts and assembly's containing both original and standardized elements. The parametric technology allows quickly obtaining models for typical products basing on a once designed prototype.




ImplicitCAD is a programmatic CAD program, implemented in Haskell. Unlike traditional CAD programs, programmatic CAD programs use text descriptions of objects, as in programming. Concepts like variables, control structures and abstraction are used, just as in programming.

HeeksCAD is a free, open source, CAD application - Imports solid models from STEP and IGES files. Draws construction geometry and lines and arcs. Creates new primitive solids, or make solids by extruding a sketch or by making a lofted solid between sketches.
