Extending compas_fab

This section is for contributors extending compas_fab — adding a backend, building the Grasshopper components, or working on the internals.

• Backend architecture: how clients, planners and backend features fit together; the contract a new backend must implement. The API reference for the extension points lives alongside it: interfaces (the abstract contracts) and the per-backend implementations for ROS + MoveIt, PyBullet and analytical kinematics.
• ActionChain design notes: technical notes regarding the current and future implementation of the Action / ActionChain data containers.
• Grasshopper components: building and installing the Grasshopper user objects.
• Icon system: details of the design system used for the Grasshopper icons.
