Cadwork Api Here
The cadwork API unlocks significant efficiencies for timber construction and prefabrication by bridging design intent with fabrication execution. Successful integrations balance technical translation (geometry and joinery fidelity) with practical concerns (versioning, licensing, and shop verification). Start small, validate thoroughly, and iterate toward fuller automation and BIM interoperability.
If you want, I can: produce a short sample script outline for reading parts via a cadwork SDK (specify target language), draft a data-mapping plan to convert cadwork elements to IFC entities, or sketch a CNC export pipeline. Which would you prefer?
The Cadwork API (Application Programming Interface) is a powerful development framework that allows users and developers to extend the core functionality of Cadwork 3D, the leading software for timber construction and BIM modeling. By using scripting languages like Python or C++, the API enables the automation of repetitive tasks, the creation of custom plugins, and the seamless integration of Cadwork data with external enterprise resource planning (ERP) or production systems. Core Capabilities and Features
The API provides deep access to the Cadwork 3D engine, allowing for programmatic manipulation of geometric and metadata elements. Key features include:
Automated Geometry Creation: Programmatically create and manipulate parts, such as beams, panels, and complex 3D connections, without manual drafting.
Data Extraction and List Generation: Automate the production of material lists, production lists, and hardware calculations directly from the 3D model.
Custom User Interfaces: Create specialized dialogs and menus using Python toolkits like Tkinter to guide users through specific workflows.
Import/Export Automation: Develop custom export routines to share data with CNC machines, web viewers, or BIM management tools.
Element Attributes: Manage and modify an unlimited number of user attributes to structure design data for BIM compliance. Development Ecosystem
Cadwork has increasingly focused on making the API accessible through modern scripting environments:
Python Integration: Since version 27, Cadwork has offered a robust Python API (CwAPI3D). It uses CPython, allowing developers to leverage a vast ecosystem of standard and third-party libraries for complex calculations or data handling.
Integrated Learning Environment: The software includes Python IDLE, an environment for writing and testing scripts directly within the Cadwork interface.
CwAPI3D Package: For advanced users, the cwapi3d package can be installed via PyPI to enable development in professional IDEs like Visual Studio Code or PyCharm.
Rhino/Grasshopper Link: Through Rhino.Inside Cadwork, developers can use Grasshopper’s visual programming to drive parametric designs directly into the Cadwork 3D environment. Practical Applications
The API is commonly used to build "helpers"—small, specific plugins that solve niche engineering problems. Examples include:
Dual Export Plugins: Simultaneously exporting shop drawings for both a container and its individual components to streamline production.
Automated Framing: Extending the standard framing modules to include specialized joinery or proprietary hardware connections.
ERP Connectivity: Linking the 3D model to external databases to ensure real-time synchronization between design and stock management. News Version 30 - cadwork 3D cadwork api

The Cadwork API (primarily the for Python) allows you to automate repetitive tasks, create custom geometric elements, and extend the functionality of Cadwork 3D without modifying the core software. 1. Initial Setup
To start scripting, your environment must be configured so Cadwork recognizes your plugins. Locate the API folder : Open Cadwork 3D and navigate to Help → Info . Click on the Userprofile folder link. Directory Structure : In your Userprofile, navigate to 3d\API.x64 Create a Plugin
: Every script requires its own folder. The folder name and the must be identical .../API.x64/MyTool/MyTool.py Icon (Optional) : Add a 30x30 pixel file with the same name (e.g., MyTool.png ) in the same folder to see it in the Cadwork Plugin Bar 2. Core Programming Concept The API is organized into Controllers , each managing specific aspects of the model. element_controller
: Used to create, modify, or query elements like beams and panels. utility_controller
: Used for user interactions, such as picking points in 3D or showing dialog boxes. geometry_controller
: Handles mathematical operations and 3D coordinate transformations. 3. Basic "Hello World" Script

Unlocking Automation: A Deep Dive into the Cadwork API In the world of timber construction, precision and speed aren't just goals—they are survival requirements. As projects grow in complexity, manual modeling often becomes a bottleneck. This is where the Cadwork API
changes the game. By moving beyond standard tools and into the realm of custom scripting, you can automate repetitive tasks, ensure flawless consistency, and push the boundaries of what’s possible in 3D design. What is the Cadwork API?
The Cadwork API (Application Programming Interface) is a bridge that allows external scripts to interact directly with Cadwork 3D. While Cadwork has long supported powerful built-in modules, the API—specifically the Python-based interface
introduced in version 27—empowers users to write their own "helpers" and plugins.
Whether you need to manipulate thousands of parts at once or generate complex list calculations, the API provides the hooks to do it without changing the core program code. Why Python? The Modern Standard
Cadwork chose Python for its API for several strategic reasons: Accessibility
: Python is famously beginner-friendly with a readable syntax, making it accessible to engineers who aren't full-time developers. Vast Ecosystem : Because it uses , you can integrate standard Python modules like directly into your Cadwork workflows. Rapid Development
: Python allows you to write powerful automation in fewer lines of code than older languages, speeding up the transition from "idea" to "working plugin". Transformative Use Cases What can you actually
with it? The possibilities range from "quality-of-life" fixes to total workflow transformations. 1. Part Manipulation and Geometry
The API allows for the programmatic creation and modification of 3D parts. You can: Automate repetitive modeling
: Instantly create plate-and-hole configurations or complex prismatic solids based on input parameters. Geometric analysis
: Calculate distances between 3D points or filter elements based on specific geometric limit values. 2. Attribute Management Data is just as important as geometry in BIM. The API’s Attribute Controller Auto-tagging
: Automatically assign user attributes to elements to structure the design. Mass updates
: Change material properties or production types across thousands of elements simultaneously. 3. List and Output Automation cadwork is a leading 3D CAD/BIM software widely
One of the most time-consuming parts of any project is documentation. The API can: Generate custom reports : Run list calculations and outputs directly via script. Batch Exporting
: Use the API to handle various import and export functions, ensuring data consistency across different trades. Getting Started: From IDLE to Advanced Plugins
Starting with the Cadwork API doesn't require a massive infrastructure. Cadwork Documentation
The cadwork API (officially CwAPI3D) is a programming interface that allows you to automate tasks and create custom plugins within cadwork 3D. It primarily supports Python, though a C++ interface is also available. Core Functionality
The API provides "Controllers" to interact with different parts of the 3D model:
Element Controller: Create, modify, copy, and delete architectural and structural elements (beams, panels, drillings).
File Controller: Manage exports and imports for various formats like IFC, Rhino, STEP, and STL.
Utility Controller: Access general data like camera positions, coordinate systems, and visibility states.
Attribute Controller: Read and write user attributes for BIM and data management. Getting Started with Python
Installation: You can install the local stub package via pip to get IDE autocompletion: pip install cwapi3d.
File Structure: Scripts must be placed in your user profile folder under ...\3d\API.x64\. Every script requires its own folder, and the Python file must share the folder's name (e.g., MyPlugin/MyPlugin.py).
Running Scripts: Once placed, your script appears as a button in the Plugin Bar (Window -> Plugins) within cadwork 3D. You don't need to restart cadwork to test code changes; simply save the .py file and click the button again. Development Resources Cadwork Python Documentation
