FreeCAD

An open-source parametric 3D software, FreeCAD offers an easy modification of 3D designs. The software is completely free to use and offers a complete set of design tools for creating detailed and complex models.

Among its varied features are a modular architecture (for plugins mounting to the core application), a Sketcher for 2D shapes, a Path module for mechanical machining like milling, and others.

CATIA

CATIA is among the best software available for modelling solid, sheet, and surface that allows easy drafting and billing of materials, analysis tools, and powerful rendering options.

CATIA has a versatile work environment, with a favoured, user-friendly, and intuitive interface, and loads of features. The software is praised for its part design and assembly design workbenches, as well as quite an easy process of designing and editing solid parts and diverse file format support.

However, CATIA has a slight learning curve and is quite costly, as a fully functional base license can be purchased for $11,200, in addition to the $2,000 annual maintenance. Moreover, you are going to need a good processor and graphics card, as CATIA is going to take up plenty of your hard drive and memory.

But despite all the downsides, CATIA remains one of the leading 3D modelling software for everyone who wants to design and create functional and quality products.
