### 1. Build your Adaptive Plan Library

* Draw a unit plan in your project.
* The plan can be saved as a new plan to your Adaptive Plan Library by selecting **`Save to Library`** at the bottom of the right panel.

### 2. Adhere to regulations with constraints

* Navigate to your plan library by clicking on **`Plans`** in the upper menu.
* Select the desired plan in your library and edit it.
* Select **`stretch preview (shift + s)`** and drag the bounds of the plan to see how it will be stretched or shrunken.
* Select the **`constraints (shift + c)`** button and click on walls that you want to lock, turning them red.
  * Click on walls twice to add an **`extendable constraint`**, where the wall can stretch but not shrink. This can be ideal for doorways, or rooms with a minimum width.
* Select the stretch preview again to see how the locked walls no longer stretch with the rest of the plan.
