Cadwork Api !!install!!

cadwork is a specialized CAD/CAM software primarily used in the timber construction industry. Unlike general-purpose CAD tools (like AutoCAD), its API is deeply integrated with wood construction logic (panels, beams, joints, lists).

Important Note: The cadwork API is proprietary. The official documentation is provided to license holders via the cadwork helpdesk or the "Help" section within the software. cadwork api

Below is a detailed guide on the architecture, requirements, and practical usage of the cadwork API. cadwork is a specialized CAD/CAM software primarily used

Use Case 2: Dynamic Camber Calculation

For long-span glulam beams, camber (upward curvature) is mandatory. Using the API, engineers extract the beam's support points and self-weight, calculate the deflection curve (using an external structural library), and write the camber values back into the beam's geometry as a vertical curve—all without leaving cadwork.

Step 2: Add References

  1. In the Solution Explorer, right-click References -> Add Reference.
  2. Click Browse.
  3. Navigate to your cadwork installation directory (e.g., C:\cadwork\v30\).
  4. Select the necessary DLLs:
    • cwAPI.dll
    • cwBaseTypes.dll
    • cwGeometry.dll
  5. Crucial: In the Properties of these references, set "Copy Local" to False. The plugin must use the DLLs loaded by the cadwork application, not local copies.

7. Troubleshooting & Best Practices

  1. Units: cadwork API operates strictly in Millimeters. Always convert user input (inches/meters) to mm before passing to API.
  2. Error Handling: Wrap API calls in try-catch blocks. Accessing a deleted element ID or invalid geometry can crash the host application. 
    try
var el = _api.getElement(id);
    // logic
catch (Exception ex)
_api.messageBox("Error: " + ex.Message);
  3. Regeneration: After bulk changes, call _api.regen() to update the 3D view. However, call it sparingly as it is resource-intensive.
  4. Null Checks: Always check if getElement returns null. An ID might exist in the selection cache but be deleted from the model.
