4 Which Free 2D CAD Software Is the Simplest to Use?ĭrawing the projected views of an object on two planes (x and y-axes) without creating a 3D model is known as two-dimensional computer-aided design, or 2D CAD.3 Why Should You Try 2D CAD Drafting Instead of Manual Drafting?. ![]() Full-featured modeling in a straight forward interface that is easy for beginners to pick up. One of the most popular 3D modeling programs available for free is Amapi. Rhino also has lots of built-in solids analysis capabilities, such as detecting leaks in seams, heat distribution through solids, or weight/applied force through a structure.Ī relatively-newer player in the CAD scene is Revit from Autodesk - supplying you with pre-built solid shapes and capable of analyzing just about any applied force or effect, but at a high learning curve. Although not a conventional CAD application, it has an incredibly short learning curve, an ability to create wonderfully intricate shapes of ALL kinds, and built-in rendering capability. My personal favorite for general design is Rhinoceros 3D CAD from McNeel and Associates. ![]() Definitely far from my favorite tool, but popular with beginners or those intimidated by full CAD programs. ![]() Somewhat constrained in ability to make organic shapes.Īs mentioned, SketchUp is a handy little app for, as the name implies, sketching ideas up quickly - but can be done with attention to dimensions, etc. If all you need is one quick project, most CAD packages have some sort of 30-day trial (always with a "personal use only" agreement, often with watermarks on the output, occasionally with no ability to save a file).ĪutoCAD is a standard default for just about anything - a little intimidating at first, but the busy interface can be easily simplified and cleaned up to hide the advanced functions.
