When I was a fresher, I was asked many times if I know CAD. No one can answer this question better than a fresher. It’s a virtual prototype of your actual product or part Why Do We Need Free CAD Software? You will have a clear view of the object and you will feel like it’s the real physical object on your computer screen. What is a 3D CAD ( Three Dimensional CAD)ģD CAD represents an object using three directional vectors ( X, Y & Z).

This won’t give you any pictorial overview of the actual object and you need to combine multiple 2D views to get a fair idea about the object. Two-dimensional CAD represents an object using only two directional vectors, X & Y. In a nutshell, you can say that CAD creates a virtual part which is as good as a physical part. Not only the loading condition but CAD can also check how the part may behave in different thermal conditions. What that means is that CAD checks for any interference with counterparts and how it may perform in different loading conditions. CAD saves engineers time and money in building a physical part. But with CAD you can have an idea about the part on the computer screen itself. Without CAD you need to prototype the part to get an overview of the part. What Is CAD ( Computer-Aided Design)ĬAD is a computer program to create 2D ( Two dimensional) and 3D ( Three dimensional ) geometry which is a kind of virtual mock-up of the actual part. So ultimately you will be left with only one choice, Using Free CAD software. But if you are not a student then you can not grab a copy of the software. Some CAD software offers a student version. Some CAD software has a trial version but most of the features will be locked. The license cost of CAD software is too high for an individual to effort. So in this article, we are going to talk about the 5 Best Free 3D CAD software. There is multiple free CAD software available in the market.

Right? But do you know that you can even get free CAD software? That sounds surprising but true. Everyone loves kinds of stuff which are free.
