Lesson 4A: Convert script to an Add-in(C++/Python)
Python C++ After creating an add-in, we’ll have a project structure like below. Same as the script, they entry point is in the BasicAddin.py. Let’s take a look at it. # Assuming you have not changed the general structure of the template no modification is needed in this file. from . import commands from .lib…

Lesson 2: Understand the document
#include <Fusion/Components/Component.h> // Get the value of the property. Ptr<Features> propertyValue = component_var->features(); std::string processProperty(const Ptr<Property>& property) { const char* propertyObjectType = property->objectType(); if (strcmp(IntegerProperty::classType(), propertyObjectType) == 0) return processIntegerProperty(property); if (strcmp(StringProperty::classType(), propertyObjectType) == 0) return processStringProperty(property); if (strcmp(BooleanProperty::classType(), propertyObjectType) == 0) return processBooleanProperty(property); if (strcmp(FloatProperty::classType(), propertyObjectType) == 0) return processFloatProperty(property); if (strcmp(ChoiceProperty::classType(), propertyObjectType) ==…

Lesson 1: The basic scripts and Add-in
Python/C++ Typescript 1. Launch Fusion, find utilities and click at the drop menu of ADD-INS button. You can find Scripts and Add-ins menu item. 2. Click at it, in the new window, we can create two types of add-ins: Scripts and Add-ins. There isn’t much different between them technically. The script will run at once…

Exploring Fusion Design Model Hierarchy Using the Manufacturing Data Model API (Not Fusion Software)
<?xml encoding=”UTF-8″>by Chandra shekar Gopal, Why Explore Model Hierarchies? When working with Fusion designs, understanding the complete structure of your assemblies, components, and subcomponents is crucial for effective manufacturing data analysis, automation, and downstream workflows. ⚡ Important: This workflow retrieves your Fusion design’s Model Hierarchy directly from the cloud using the Manufacturing Data Model API, not…
