You can unlock unrestricted access to the AutoCAD student version if you are a student. You need to provide the essential student identity detail and use the product for at least one year.

Besides educational purposes, Autocad comes with free trials that offer an entire AutoCAD suite like AutoCAD Electrical, AutoCAD Architecture, and more.

AutoCAD is advanced computer-aided design software to create precise 2D and 3D drawings for working professionals like engineers and architects.

You can design, draft and annotate 3D models and 2D geometry with surfaces, solids, and mesh objects.

The AutoCAD comes with specialized features and a library that helps perform 3D mapping, mechanical design, and architecture.

Further, the specialized features and toolsets come with industry-specific functionality and the latest feature updates.


FreeCAD free CAD software program

FreeCAD is an open-source, free CAD software program that helps design parametric 3D modelers.

The parametric 3D modeler can build objects of any size and can modify objects by going back to model history and changing parameters.

FreeCAD is suitable to accomplish much wide range of designs, including architecture, mechanical engineering, and product design.

Moreover, FreeCAD is equipped with multiple tools like Finite Element Analysis (FEA) tools, dedicated BIM, experimental CFD, Geodata or CAM/CNC workbenches, and a robot simulation module.

FreeCAD is highly customizable and extensible software that supports multiplatform like Windows, Mac, and Linux.

The output file format for FreeCAD is SVG, OBJ, DAE, STEP, IGES, STL, and many others.

Sketchup Free

Sketchup Trimble free CAD software program

Sketchup is another free CAD software program available for schools with a GSuite or Microsoft education account.

You can create 3D modeling and design sustainable buildings with SketchUp software.

Further, you can sketch 2D shapes by taking inspiration from 3D models and vice versa.

Google originally built SketchUp, and later on, it was sold to Trimble.

Trimble enhanced and developed the advantage features and created a wide range of design and drawing applications.

It caters to multiple verticals like landscape architecture, product design, civil and mechanical engineering, architectural and interior design, and much more.

SketchUp is useful in 3D visualizing, modeling, and rendering.


Onshape free CAD software program

Onshape is another free CAD software program that caters to non-professional designers.

You can access Onshape from any device, use the sharing and collaboration feature, and secure your data from losses.

Onshape software program is based on parametric modeling that benefits multi-part design, configuration, standard content, managed in-context design, and simultaneous sheet metal tools.

Further, Onshape has an active community and self-paced training program that make your learning curve practical and enjoyable.

Once you are skilled enough and like to access professional tools, then move to Onshape Professional software program.


OpenSCAD free CAD software and app

OpenSCAD is another free-to-use 3D CAD software program available for Windows, macOS X, and Linux/Unix.

Unlike other CAD software program, which focuses more on 3D modeling, OpenSCAD focuses more on essential aspects of CAD.

It is a type of application that helps you create and plan 3D models of machine parts.

Also, OpenSCAD is not an interactive modeler; instead, it is a 3D compiler that describes the 3D model object and renders it from the script file.

The advantage of the 3D compiler is that it gives complete control over the modeling process.

Also, it lets you change the steps in the modeling process design that are defined by configurable parameters.


LibraCAD free CAD software app

LibraCAD is another free open source CAD software program for Windows, Mac OS, and Linux.

Further, LibraCAD doesn’t require any trials, subscription, or license to run the software program.

It has an uncluttered user interface suitable for 2D CAD programs for beginners. Moreover, LibraCAD doesn’t have much functionality and appealing feature to satisfy advanced users.
