How to choose a CAD software for beginners
As stated above, there are many aspects to consider when it comes to choosing the appropriate CAD software for you, in this sense here’s a list of the key factors you need to keep in mind when making that decision:
This is an important factor when making any financial decision and will always depend on the user´s budget. In terms of costs, the most affordable CAD software in the market is FreeCAD, LibreCAD (both open-source programs), Fusion 360 (the most affordable Autodesk license), SketchUp, and Rhino 3D.
Application and field of study
Some CAD software available in the market provides specific tools for certain fields so users can create their drawings efficiently. AutoCAD and SketchUp are the most popular programs for architects and interior designers. In the case of mechanical engineers, Inventor, SolidWorks, and Fusion 360 are the best options. For jewelry design many users like Rhino 3D and for the automotive industry CATIA is the top-leading CAD software.
Hardware and software requirements
Some CAD software require powerful hardware and great graphical data storage to function properly. Also, some CAD software is not supported on free operating systems such as Linux (like Autodesk’s software) or doesn’t have a license to run on Apple iOS (such as SolidWorks). In this sense, it is always important to check the hardware and software requirements of a program before buying it.
Level of difficulty
Some CAD programs require more training to create drawings and master their tools than others. Professional CAD software like CATIA or SolidWorks is not as user-friendly as other programs like Fusion 360, so it will depend on the learner to spend more time familiarizing themself with the software. However, there are always online guides and tutorials that can make learning CAD a lot easier.
Best CAD software to start learning CAD
Nowadays, there are many available options for software for 2D and 3D modeling. Engineers, architects, and designers usually specialize in a particular program or platform due to its features, interface, and design tools. There are CAD programs more oriented to certain fields like SketchUp (mainly used by architects and interior designers) or Autodesk Inventor (designed for mechanical engineers).
However, learning any CAD software can help beginners to understand other programs and get familiar with CAD design, how to create models and how to establish a design path.
Regardless of what your software of preference is, you need to keep in mind your field of work, the purpose of your designs, and which tool will be more appropriate and affordable for you.
