Custom Features

FeatureScript is a programming language developed by Onshape specifically for creating custom features and tools within the Onshape CAD platform.

With FeatureScript, you can create custom parametric features, automate repetitive tasks, develop specialized tools, and extend the functionality of Onshape to suit your specific needs.

No. To use an existing custom feature, just add it to your toolbar and use it like any other feature. If you want to create your own features, then a basic knowledge of programming techniques will help you to learn FeatureScript faster. Onshape provides comprehensive documentation and tutorials to help you get started.

FeatureScript is a proprietary language developed by Onshape, it is based on JavaScript but has its own syntax and conventions.

Yes. You can share your custom features publicly or privately within your company or enterprise environment.

Public sharing: Publish your public custom feature to make it searchable to all Onshape users. Sharing your creations allows other users to benefit from your innovations and can contribute to the growth of the Onshape community.

Private sharing: Custom features are contained within Onshape Documents and can be shared just as you would share a part. To share it to all users of your company, share it to the team called All company users.

Unlike macros, Custom Features in Onshape are fully integrated into the parametric modeling environment, allowing for seamless interoperability with native features.

Here are some ways in which custom features are better than legacy CAD macros:

• Custom Features are more robust, they regenerate correctly even when there are changes to the CAD model.
• When you create a custom feature it references a specific version of the Onshape feature library. This means that your custom feature never breaks because it is linked to the feature library it was originally created with and you can enjoy Onshape’s continuous updates every 3 weeks without hassle.
• Deploying changes to your custom features is very easy. If there are modifications to a shared custom feature users are notified and given the option to upgrade or not.

Onshape provides support resources, including documentation, tutorials, training courses, and community forums. If you encounter difficulties or have questions while using FeatureScript, reaching out to the Onshape community via the forum is recommended.
