Best Basic Design for Learning

Students use Onshape to learn basic CAD skills and designing parts for additive manufacturing. They use mostly basic functionality of the software, but do utilize the collaborative component. As the teacher the monitoring and support aspects are developing and getting much better than when I was first introduced to the program. I can now send students starter documents and set up collaborate groups. I don't limit available features, but I know that is also available. The biggest problem for me that this program addresses is it's capability to operate completely within a web browser. Most students only have school chromebooks that don't have the memory space to support a downloaded program so being able to access through a web browser is a big plus despite any limitations that creates.
