3D modeling of a house using FreeCAD

It is a type of CAD software used extensively by civil engineers, mechanical engineers, industrial engineers manufacturing engineers, product developers, designers, and drafters. It utilizes a system of Non-uniform rational basis spline or NURBS that is commonly implemented in graphic designing for the representation of curves and surfaces, unlike other software that imitates curves by using gently inclined surfaces. It also has additional features like 3D solid modeling, design simulation of products, checking manufacturing defects, cost estimation, data management for products, and many more. It has applications in industries like aviation, product manufacturers, medical, oil and gas, and consumer products. It is a professional level software so a licence has to be purchased to use it.

It is used by structural engineers and architects for project management and building analysis as it offers sophisticated tools. Not only that, it enables to convert drawings to a stereolithography file or STL, that plays an important role in 3D printing. It has features such as 3D visualisation, Mechanical/Electrical/Plumbing or MEP modeling and detailing, modeling of steel structures, prefabrication of building components and so on. It is produced by Autodesk company that provides free version for a period of 30 days after which a license is required. Students can acquire this software free of cost..
