This is an interesting list of the “top 10” CAD; however, It looks like it may be based on a “consumer standpoint” with free/open source software being ranked higher. Fortunately, as robotics students, you all have the unique opportunity to use learn and use most of the leading CAD software with no-cost educational licenses. Here is an article which lists the top CAD software as used in industry in 2021. 10 CAD Systems Employers Want (2023) - Apollo Technical
Topping the list is Solidworks and Inventor. Also on the list are leading CAD packages used for civil engineering and building applications (a big part of the market that mechanical engineers don’t usually get involved with).
Here’s what you need to find the student licensing for these CAD packages:
Solidworks (Mentor/Coach must apply): SOLIDWORKS Sponsorship for Student Teams | SOLIDWORKS
Autodesk programs (Inventor, Fusion, Revit, AutoCad): Autodesk Education & Student Access | Autodesk
Creo: https://www.ptc.com/en/products/education/free-software/creo-college-download
UGNX: NX Student Edition Free Download - NX Design
Microstation and Catia do not have student download versions.
Additional CAD software that is industrial-quality, but not on the “top 9” for 2021 include Onshape and Solid Edge.
OnShape (much of the features of SolidWorks but runs in a browser-based application on the OnShape remote servers, so even a Chromebook can run the program): Education Plan | Onshape Product Development Platform
SolidEdge: Solid Edge Student Edition
