EASY CAD PRO is a general purpose feature-based, parametric 3D modeller for CAD, MCAD, CAx, CAE and PLM, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is 100% Open Source and extremely modular, allowing for very advanced extension and customisation.

EASY CAD PRO is based on OpenCasCade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad Python API. The interface is built with Qt. Easy CAD runs exactly the same way on Windows platforms.

Features

Rock-solid OpenCasCade-based geometry kernel, allowing complex 3D operations on complex shape types, and supports natively concepts like brep, nurbs, booleans operations or fillets

Full parametric model allowing any type of parameter-driven custom objects, that can even be fully programmed in python

Complete access from python built-in interpreter, macros or external scripts to almost any part of EASY CAD PRO, being geometry creation and transformation, the 2D or 3D representation of that geometry (scene-graph) or even the EASY CAD PRO interface

EASY CAD PRO is a parametric 3D modeller. Parametric modelling allows you to easily modify your design by going back into your model history and changing its parameters. EASY CAD PRO is open source (LGPL license) and completely modular, allowing for very advanced extension and customisation.

EASY CAD PRO is multi-platfom, and reads and writes many open file formats such as STEP, IGES, STL and others. Read more...

Who is EASY CAD PRO for?

The home user/hobbyist. Got yourself a project you want to build, have built, or 3D printed? Model it in EASY CAD PRO. No previous CAD experience required. 

The experienced CAD user. If you use commercial parametric modelling software at work, you will find similar tools in EASY CAD PRO.

The programmer. Most of EASY CAD PRO's functionality is accessible to Python. You can easily pilot EASY CAD PRO from scripts, build your own modules or even embed EASY CAD PRO in your own application.

The educator. Teach your students EASY CAD PRO software with no worry about license purchase. They can install the same version at home and continue using it after leaving school.

BRL-CAD is a powerful cross-platform Open Source combinatorial Constructive Solid Geometry (CSG) solid modelling system that includes interactive 3D solid geometry editing, high-performance ray-tracing support for rendering and geometric analysis, network-distributed frame-buffer support, image and signal-processing tools, path-tracing and photon mapping support for realistic image synthesis, a system performance analysis benchmark suite, an embedded scripting interface, and libraries for robust high-performance geometric representation and analysis.

What is BRL-CAD?

Since the late 1950s, computers have been used to assist with the design and study of combat vehicle systems. The result has been a reduction in the amount of time and money required to take a system from the drawing board to full-scale production as well as increased efficiency in testing and evaluation.

In 1979, the U.S. Army Ballistic Research Laboratory (BRL) (now the U.S. Army Research Laboratory [ARL]) expressed a need for tools that could assist with the computer simulation and engineering analysis of combat vehicle systems and environments. When no existing computer-aided design (CAD) package was found to be adequate for this purpose, BRL software developers began assembling a suite of utilities capable of interactively displaying, editing, and interrogating geometric models. This suite became known as BRL-CAD.

Now comprising almost a million lines of C code, BRL-CAD has become a powerful constructive solid geometry (CSG) modelling package that has been licensed at over 2,000 sites throughout the world. It contains a large collection of tools, utilities, and libraries including an interactive geometry editor, raytracing and generic frame-buffer libraries, a network-distributed image-processing and signal-processing capability, and a customisable embedded scripting language. In addition, BRL-CAD simultaneously supports dual interaction methods, one using a command line and one using a graphical user interface (GUI).

A particular strength of the package lies in its ability to build and analyse realistic models of complex objects using a relatively small set of "primitive shapes." To do this, the shapes are manipulated by employing the basic Boolean operations of union, subtraction, and intersection. Another strength of the package is the speed of its ray-tracer, which is one of the fastest in existence. Finally, BRL-CAD users can accurately model objects on scales ranging from the subatomic through the galactic and get "all the details, all the time.”
