Building Engineering Modelling and Analysis Addons in Blender

Unleash the power of Blender by building custom tools to speed up your workflows

After completing this course...

You’ll be able to build custom logic directly inside Blender and build your own sharable tools in the form of addons.
You’ll understand how to add custom UI elements such as buttons, menus and panels into the Blender interface.
You’ll be comfortable using a combination of Serpens, the intuitive and user-friendly node-based development workflow and custom scripting to develop your addons.
You’ll understand how to implement custom analysis code in your addon and leverage Blender’s 3D capabilities for modelling and visualising structural behaviour.
