7 Best 3D CAD Modeling Software Tools for Engineers

3D Modeling and Computer Aided Design (CAD) software tools have really helped to different aspects of engineering very simple and more accurate. In industries, before you build anything physically, you need to use 3D CAD software to make the modelling, design and simulate it. Then save it in the Stereolithography (SLT) file format if you wish to print it. I have taken time to reveal these easy to use software tools that can help you with your 3D modeling and CAD as an engineer. No matter your field in engineering, be it electrical, civil, mechanical (production, automobile), mechatronics, structural, chemical, and even architects, you will find a software that will suit you, both in budget and in features.

Difference Between 3D Modeling, CAD, CAM and CAE

There is a little difference between 3D modeling software and CAD software. The main difference is that CAD software are mostly used to simplify manufacturing industrial processes. While 3D modeling software is mostly used for artistic works and in entertainment industries and also to design buildings. Both of them are related in such a way that most 3D software can be used for both 3D modeling and CAD. But the fact remains that 3D modeling is an aspect of CAD.

With further technological development, CAD was split into Computer Aided Manufacturing (CAM) and Computer Aided Engineering (CAE). This means that CAM software are used in manufacturing processes while CAM software tools are used in engineering processes. Vincent Zitzewitz explained more about CAD and CAE.
