For those not already familiar with the GrabCAD platform, here are a few resources to get started.
If you’re also new to CAD design, or are just looking to hone your skills, you can create or learn from an extensive library of member-written tutorials (https://grabcad.com/tutorials). You can also put your skills to the test in our engineering design challenges (https://grabcad.com/challenges), or discuss topics with other members by joining a group that suits your interests and goals (https://grabcad.com/groups).
As you engage with the GrabCAD Community, all are asked to consider and respect their Values and Guidelines (Community Values and Guidelines - GrabCAD Help Center). These are the official rules of the Community.
Lastly, if you have questions specifically about the GrabCAD site and services, the Help Center (https://help.grabcad.com) is a great place to start. They have assembled a collection of documents for all four of their major services - Community, Workbench, Print and Shop. And for any additional questions or suggestions, you can direct your feedback to email@example.com.
