# Site to BIM: Modelling and Exporting from Forma to Finch

## From Site to BIM – Forma + Finch Masterplanning

#### 1. Create your masterplan project in Finch

* In the Finch web app, go to the **Projects** page and click **Create New**.
* Name your project (e.g., “Forma to Finch Masterplan”) and click **OK**.

***

#### 2. In Forma – prepare buildings and context

* Prepare your site in **Forma**, complete with terrain and context (neighboring buildings, roads, trees).
* Model your buildings using different tools:
  * **Line Building** (disable “sections” to avoid splitting into multiple masses)
  * **Basic Building** tool (good for extrusions and push–pull edits)
  * **3D Sketch** tool (for more sculptural or curved geometry)
* Now your model includes 3 buildings + contextual data, ready for export.

***

#### 3. Set up variants in Finch

* Return to the Finch web app. In your new project, create **three variants**, one for each building (A, B, C), plus a fourth for **Context**.
* This setup will allow you to upload each building separately and keep context distinct.

***

#### 4. Upload your context variant from Forma

* In Forma, open the **Finch extension** (install it under Extensions if needed).
* Select your Finch project and choose the **Context** variant.
* Enable **Manual Geometry Selection**. Choose only context elements (terrain, surrounding buildings, vegetation).
* Click **Export to Finch**.
* In Finch, open the Context variant to confirm context geometry has imported properly.

***

#### 5. Upload building variants from Forma

* In Forma, select the **Building A** variant in the Finch extension.
* Click **Manual Geometry Selection**, then **click the roof/top surface** of Building A (selecting the side will not work).
* Click **Export to Finch**. Repeat this process for **Buildings B and C**, assigning each to their corresponding variant.
