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




PTC Creo is described as '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' and is a CAD software in the photos & graphics category. There are more than 50 alternatives to PTC Creo for a variety of platforms, including Windows, Mac, Linux, Web-based and BSD apps. The best PTC Creo alternative is FreeCAD, which is both free and Open Source. Other great apps like PTC Creo are SketchUp, LibreCAD, Autodesk AutoCAD and OpenSCAD.

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.



OpenModelica – A Free Modelica Environment! OpenModelica is an open-source Modelica-based modeling and simulation environment intended for industrial and academic usage. Its long-term development is supported by a non-profit organization – the Open Source Modelica Consortium (OS.

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:


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.




CadQuery is an intuitive, easy-to-use Python module for building parametric 3D CAD models. Using CadQuery, you can write short, simple scripts that produce high quality CAD models. It is easy to make many different objects using a single script that can be customized.


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.




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.


PyDSTool is a sophisticated & integrated simulation and analysis environment for dynamical systems models of physical systems (ODEs, DAEs, maps, and hybrid systems).
Create, edit, view, and print 2D CAD drawings using the file formats: dxf, dwg, shp ;Download-Size only 3.10 MB; language: only english;

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.
