People have created custom features, called *FeatureScripts*, that are especially useful for designing FRC robots. onshape4frc.com has [a nice guide](https://onshape4frc.com/cad-library#Featurescripts) on the FeatureScripts we'll use. {% hint style="info" %} Check out this thread on ChiefDelphi (it's massive and constantly growing). It's where FRC folks discuss all of their favorite new FeatureScripts. {% endhint %} ## MKCad There's also a common parts library, called *MKCad*, where you'll find things like motors, gearboxes, wheels, shafts, spacers, and so much more... Basically, all of the common parts used in FRC have already been modeled for you! Please watch this video to learn how to use the common parts in MKCad and convenient FeatureScripts. *(Thanks for the video, Spectrum!)* Follow along so you can practice using these tools! {% embed url="" %} Also, check out [onshape4frc.com](https://onshape4frc.com/). This is a helpful resource with guides on how to use FeatureScripts, MKCad, design calculators, and more. Now, you're ready to work on your design skills and start creating real FRC robots in Onshape! --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.wcrobotics.org/training/onshape-training/featurescripts-and-mkcad.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
