# Link Diaphragm Shear

> Link diaphragm shear into a shear wall calculator and size sheathing, studs and hold-downs.

Complete the lateral load path by designing the shear wall that receives diaphragm loads.

Key steps:

* **Add shear wall calculator:** Search for "Shear Wall" and create a new calculation
* **Link shear force:** Instead of typing manually, click the link button and select your diaphragm → Wall Line 1
* **Structural parameters:** Story height and number of stories (extracted from Project Defaults); sheathing and studs are selected via the member selector
* **Member selection:** Use the member selector with quick visualization of section performance
* **Hold-down design:** If capacity fails, adjust hold-down or nail spacing

<Note>
  **See it in action:** Change the wind speed in Project Defaults, and all linked calculators (wind, diaphragm, shear wall) update automatically. No manual re-entry required.
