Looking for AutoCad alternative?
Most professional 3D CAD software is expensive, however there are always some free 3D CAD programs that you can use and create the magic. Here are some free 3D CAD Software or AutoCad alternatives out there that that help you in 3D CAD designing, drafting, modelling, architectural drawing, and engineering work.
FreeCAD is a freewares and open source general purpose 3D CAD modeler. FreeCAD allows users to create and manipulate assemblies, which are collections of parts. It is intended to be a feature-based parametric modeler with a modular software architecture, which makes it easy to provide additional functionality without modifying the core system.
FreeCAD is also fully multi-platform, and currently runs flawlessly on Windows and Linux/Unix and Mac OSX systems, with the exact same look and functionality on all platforms.
Creo Elements/Direct Modeling Express is a free 3D CAD application. It is a very fast and flexible alternative to AutoCAD with many options included that AutoCAD is known for having. Creo Elements/Direct Modeling Express’s flexible modeling approach is not just for 3D modeling; it extends to 2D sketching as well. Creo Elements/Direct Modeling Express helps any engineer, designer, or student create standard, compliant 2D drawings from 3D models using just a few simple menu picks.
OpenSCAD is a free 3D modelling program in which you type commands to alter objects. OpenSCAD is not an interactive modeller. OpenSCAD is ideal for those who are looking to work on the specifics. It is something like a 3D-compiler that reads in a script file that describes the object and renders the 3D model from this script file.
