FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters.
QuickCAD CAD files are only supported by QuickCAD. In order to open them in another program, the files must be converted to a more widely supported format, such as the AutoCAD Drawing.DWG format or Drawing Exchange.DXF format. Unfortunately, the only program able to convert QuickCAD CAD files is Autodesk QuickCAD, which is no longer developed. STEP files (.stp) for 3D and assembly are often used by all major mechanical CAD systems. With our absolutely free STP Viewer you can easily open 3D files (.stp), rotate them and perform some basic actions like: zoom, rotate, move or change skin.

.CAD File Association 2
A CAD file is a CAD file created by Autodesk QuickCAD, a CAD 2D vector drawing program that was discontinued in 2004. It contains a technical 2D drawing, which includes geometry and measurement information. CAD files are often used for storing floorplan layouts and mechanical designs.
QuickCAD CAD files are only supported by QuickCAD. In order to open them in another program, the files must be converted to a more widely supported format, such as the AutoCAD Drawing .DWG format or Drawing Exchange .DXF format. Unfortunately, the only program able to convert QuickCAD CAD files is Autodesk QuickCAD, which is no longer developed.
NOTE: Autodesk QuickCAD was originally Softdesk Drafix Quick CAD in the 1990s. But when Softdesk was acquired by Autodesk, Drafix Quick CAD was repackaged as Autodesk QuickCAD, which was developed until version 8 in 2004.

Anyone who has worked with CAD will know just how integral the software is to various industries—ranging from architecture, to engineering and even gaming. CAD gives us the ability to create designs for a range of purposes, from electrical drawings to house plans. This high demand, however, has meant that professional CAD software has become very expensive—particularly for those who just enjoy CAD as a hobby, and therefore don’t want to commit to an expensive package (for instance, this is how much AutoCAD costs).
With that in mind, Scan2CAD has created a list of the top 14 CAD freeware packages, so you can enjoy CAD without having to spend a single penny. We’ve included operating systems, supported file types and even a list of extra packages that didn’t quite make the list. Read on…
We’ve separated this list into two sections:
We begin our list with some of the most popular and free options for 2D drafting. If you’re new to CAD, you probably want to start here.
1. DraftSight
DraftSight is a professional 2D design and drafting program that lets you create, edit and view any kind of 2D drawing. It’s a rather simple and minimal program, so it’s easy to make the transition from another type of CAD application to DraftSight. The only requirement to use the program is to activate it via an email address. This CAD freeware program does have an AutoCAD feel to it—in fact, it even uses AutoCAD’s native file format DWG. It comes with a range of drafting tools to help you create professional plans, with a number of vector entities available including lines and polylines, dimensions, layering capabilities and text.
Operating System: Windows, Mac, Ubuntu, Fedora
File Formats: DWG, DXF, JPEG, PDF, PNG, SLD, STL, SVG, TIF

4. Draft IT
Draft IT is a 2D system, which is primarily most useful for people who are just starting out with CAD. It has no 3D and/or modeling capabilities, so you shouldn’t be expecting anything too complex. It’s essentially a system that is useful for creating plans and diagrams. That being said, some of its features are disabled in the free version, e.g. layering and polylines. To be able to do more, you would have to upgrade to the Plus or Pro version. So, if you’re looking to do serious, detailed work you might want to consider other software.
Operating System: Windows
File Formats: DWG, DXF

Image Source: OnShape
OnShape is a force to recon with when it comes to making 3D modelling more accessible to the masses. If you’re not new to CAD, you’ve probably heard of the leading 3D modelling CAD software, SolidWorks , OnShape was started by SolidWorks CEOs Jon Hirschtick and John McEleney, plus their founding team and they continue to carry the torch of SolidWorks’ innovation and quality.
OnShape is unique to many other options in that it runs in your web browser. But don’t be fooled into thinking a browser-based solution is limited. The software boasts a list of enterprise-level manufacturing companies as users so if their features are enough for these companies it will likely be enough for most entry-level users.
Although OnShape offers a premium solution, they also offer a free plan with limited features, but be warned; everything you store in OnShape under the free plan is automatically open source.

12. OpenSCAD
Image Source: Peak 5390
OpenSCAD is a 3D modeling CAD freeware platform. Unlike most 3D modeling software, it doesn’t focus on the ‘artistic’ aspects of 3D modeling. Instead, it’s more suitable for creating 3D models of machine parts, and working as a 3D compiler that describes the object and renders a 3D model from a script file. It gives the designer full control over the modeling process to make designs that are designed by configurable parameters. However, while the software is very intuitive, it’s still too limited for complex projects—so you might have to go elsewhere if you want more advanced features.
Operating System: Windows, Mac, Linux, Ubuntu, Fedora
File Formats: AMF, CSG, DXF, OFF, PNG, SCAD, STL, SVG

13. Blender
Blender is a free and open-source 3D modeling program. It’s more of an artistic 3D modeling program than a general-use drafting program. It comes with a wide set of capabilities ranging from photo-realistic rendering, to fast modeling, to realistic materials. Blender even allows designers to make use of an extensive animation toolset to turn still characters into animations. And if that wasn’t enough, the program also comes with simulation capabilities and video editing. While it is a steep learning curve with Blender, it is worth it.
Operating System: Windows, Mac, Linux
File Formats: 3DS, BVH, DAE, DFX, FBX, LWO, OBJ, PLY, STL, SVG, VRML/97, x, X3D
