3D Modeling Software Options

I’ve heard of teams using Autodesk Inventor, Autodesk Fusion 360, Solid Works, and even Blender to model parts of their robot. Are there any other options out there? I’m looking for a software that will run decently on an average laptop but have the features that will allow me to effectively model parts of the robot. My school year hasn’t started which means I can’t download the student version onto my laptop. However, I’m hoping I can get started now instead of waiting. So are there any other options that are free to download so that I can get started right away? Thank you in advance!

Some teams use SketchUp to model their robots

OnShape has VEX part libraries put together by various teams and requires no download at all. Plus it has a mobile app that you can actually do CADing with.
