🧾 What it does
The Align-Planes command allows you to align two independent roof planes together to create one roof plane. This is a powerful command that enables you to create extremely complex roof shapes, one component at a time.
🔧 How to use it
Click Modify Roof > Align-Planes
When prompted, select the plane you want to move
Select the plane you want to align it to
Choose your alignment method from the dialog box that appears
Click OK and follow any additional prompts
🧾 Alignment options
Option | Description |
Align Selected Plane Only | Only moves the originally selected plane to be aligned |
Select Planes to Move | Allows you to manually select roof planes to align |
Align Plane and Remainder of Storey | Aligns original plane and all other planes on selected storey to be moved into alignment |
🛠 Example: Creating complex roof shapes
This example shows how to align high set and low set roof sections:
Step 1: Model the high set and low set parts of the roof as two separate roof shapes.
Step 2: After using the Modify Roof > Cut-Out command to remove the area of low set roof under the high set roof, you have the roof geometry shown.
Step 3: Select the plane to use as a reference plane. In this example, it would be the back plane of the high set roof.
Step 4: Then select the plane to align with. In this case, the back plane of the low set roof. Once confirmed, they will align automatically.
Step 5: Once aligned, you may use Modify Roof > More… > Merge-Planes to combine the high set with the low set so that the roof plane is continuous from ridge to eave.
