TypeScript
The application programming interface (API) of Fusion allows you to author Scripts and Add-Ins to automate workflows in Fusion. The desktop client of Fusion can execute scripts and Add-Ins that are written in Python or C++.
Scripts for Design Automation for Fusion can only be written in TypeScript. Design Automation for Fusion will not support Python or C++ scripts. This page lays out the similarities and differences between the existing API languages and the TypeScript API and explain to you how develop scripts for the Fusion engine on Design Automation.
