Top 18 of the best open-source CAD software in 2023
Introduction
3D modeling software are useful for many different applications and could be a great asset for your business. It is a real advantage to develop your project, and it can be used forarchitectural projects, in themedical field,or even in thefashion sector. Everything is possible. In this blog post we are going to see how a 3D modeling program could help you in your daily work and what an open-source software exactly is. Then, we will seewhat are the best available open-source CAD software in order to help you find the right CAD tool for your company.
Why should you use CAD software?
3D modeling software could be useful for your company for diverse applications. It can be used by engineers or designers, and even by amateurs. It is becoming a convenient and essential tool to work on designs, prototypes, or to produce 3D printed parts. You can use it to 3D model your parts in order to 3D print them, or just for the visualization of your projects.
Do you need toimprove your design processor want toelaborate industrial designs?
These kinds of programs are particularly convenient if you are looking for a new prototyping process. Indeed, prototyping is becoming quite simple while using 3D modeling software and additive manufacturing. You can do many iterations at a lower cost, and you just have to modify your CAD model if you need to change something.
3D modeling software could also be a good solution to get a better visualization of your project or to improve your product design. From technical drawings to advanced 3D models for mechanical engineering, everything is possible if you choose the right CAD tool. We know that there is necessarily a software on the market that will fit your needs, and it may be an open-source software!
What is an open-source CAD software?
Open-Source software has a free public code that can be downloaded and modified by developers. It can be great if you want to add features to specific software in order to improve it and adapt it to the use of your business. All the community can participate in the software development, anyone can write an extension to make the software better. It clearly has a collaborative aspect.
There are various open-source CAD software programs available, that you can download for free. You can use them to create and modify your 3D models and develop your professional projects. Are you interested in starting 3D modeling with open-source CAD software? Let’s see what the best programs are for your business.
The best open-source CAD programs - General open-source software
Here is a selection of the best open-source 3D CAD software for 3D applications. You will mainly find software for advanced users, as these programs are addressed to professionals or programmers.
FreeCAD
FreeCADis a parametric 3D modeling software. You don’t need previous experience with 3D modeling to use it, but you can totally achieve complex models with it, for engineering or architecture projects. Indeed, it has professional features adapted to work for mechanical engineering. It can be used by anybody: home-users, designers, programmers, and even educators.
Blenderis a widely used open-source software. It is useful to create various 3D designs, from electronic projects to digital art. It can create impressive models, using polygonal modeling techniques. You can use Blender to create simulations and animations.
You need to be experienced with 3D modeling, but if you need a little help, Blender has a really large community, offering a lot of tutorials.
OpenSCAD is an open-source parametric software, that can be used to create 2D designs, and 3D models. It is a great tool to make 3D objects designed for additive manufacturing. While using OpenSCAD, you can’t modify directly with your mouse the CAD model that is in the viewer. This software uses its own language.
OpenSCAD is perfect if you need to create accurate models, but you have to keep in mind that it is really programmer-oriented.
Wings 3D
Wings 3D is a free open-source software. It offers a great variety of modeling tools, that could help you with all of your projects. It is a good software to create your CAD models and work on texture and materials. However, it is not the perfect tool if you need a CAD program for animation and rendering.
OpenCascade Technologyis a complete 3D modeling tool: from modeling to visualization, everything is possible. The geometric, topological and visualization algorithms of this program will allow you to create 3D models for any type of sectors, just for visualization, or for manufacturing processes.
SolveSpace
SolveSpaceis a parametric 2D/3D modeling software. It is a good tool if you need an open-source CAD software to export your 3D files for 3D printing. It has all the basic features of a 3D software, and it is possible to make complex designs. You can work on the design of an object or process mechanical simulations with this program.
Art of illusion
Art of illusionis an animation oriented software. It is an open-source program, allowing to work on 3D modeling, texturing and material, but also able to make some rendering. Art of illusion is a high end animation program, powerful enough to be used professionally.
OpenJSCAD
OpenJSCADis an open-source CAD program. It is quite similar to OpenSCAD, which we discussed previously in this blogpost, but the difference is that OpenJSCAD is a browser-based program. It is easier to use. Indeed, it is a good solution as you don’t need to install any software to create the 3D model that you want to 3D print.
Moreover, all the features are well explained on the website, you just have to follow the indications to create your own 3D designs.
JS Sketcher
JS Sketcher is a CAD program that you can access with your browser. This open-source parametric modeling software is written in javascript. For the moment, there are not too many features, so it is a simple software to use if you are just beginning with open-source programs, but you will still need a little bit of training at the beginning. This is a really promising software.
QCAD
QCADis a free computer-aided design software. It is hosted on GitHub and is open to any contributions. This 2D CAD software offers a wide range of CAD tools. This CAD program can be extended through its complete ECMAScript (JavaScript) interface.
BRL CAD
This CAD tool software has been developed by Mike Muuss at the Army Research Laboratory and used by US military. They used it for academic, industrial, or even health applications. This solid modeling system has been around since 1984, it simply became an open-source project in 2004.
It is now possible to use this program for engineering or graphic applications.
LibreCAD
LibreCAD is a free open-source CAD with a large community of users, contributors, and developers. This 2D CAD software is really complete and useful for laser cutting projects, for example. The source code can be downloaded directly from GitHub.
Salome
The open-source CAD software Salome works with Microsoft as well as Linux. It offers a wide range of different tools like sculpting and shaping. The user can also benefit from many already existing shapes, fields, or meshes in 3D. Salome can be used by users from any level.
LeoCAD
LeoCAD is a great open-source CAD software for all levels and offers a simplistic approach to the design process of a 3D model. This CAD software is available for macOS, Linux as well as Microsoft.
The best open-source CAD programs - Specific open-source applications
