SOLIDWORKS is used to develop any kind of Mechanical systems from beginning to end. At the initial stage, the software is used for planning, visual ideation, modeling, feasibility assessment, prototyping, and project management. The software is then used for design and building of mechanical, electrical, and software elements.
Most manufacturers are converting their CAD files from 2D to 3D in today’s digital environment to boost their design process and enhance communication with customers and the design team. Designers, clients, and engineers now rely on advanced SOLIDWORKS 3D CAD software for anything from designing to rapid prototyping.
In the Smart industry 4.0 of IOT manufacturing companies should take advantage of the growing opportunities for increased productivity, collaboration, and creativity that an integrated design development framework provides by making 3D CAD data the foundational DNA of the entire enterprise.
It's considered a mainstream mechanical engineering tool. It's used in enough places that It's frequently exchanged between companies for manufacturing quoting, conceptual development and analysis.
For engineers, It's like Microsoft office: people just expect you to be able to use it.
Even if a company uses Solid edge or Inventor, if you have Solidworks training, they know you know about Parametric 3D modeling.
Solidworks is one of the most popular 3D CAD packages out there. If one wants to be employed as a mechanical engineer, knowing this will definitely help one's career.
