De-tilt Tool

Overview

A variety of factors — including GPS drift, sensor variance, and site conditions — can result in a 3D model, LiDAR scan, or Google 3D dataset appearing slightly "off tilt" relative to true horizontal. In most cases, minor tilt is a normal artifact of the capture process, and small adjustments using the De-Tilt Tool can bring the model into closer alignment with reality.

When to use the De-Tilt Tool

• Two opposing roof surfaces that should be roughly even in pitch appear to have noticeably different tilts
• An obvious lean or tilt is visible in the model that doesn't reflect the actual structure
• A design workflow (such as panel layout or shading analysis) is producing unexpected results

How to perform a Flood Test

Use the Flood Test to confirm whether your model has a tilt issue and to identify the direction of the tilt before making any corrections. 

1. Open up the References dropdown.

2. Select the 3D model reference layer.

3. Click and hold on the blue arrow that appears over the 3D model.

4.  Drag it down until you can see the ridge of your subject house go under the map tile. This flat 2D surface is the base layer of your design space.

5.  If the ridge goes under the map tile unevenly, then it needs to be de-tilted. 

How to use the De-Tilt Tool

If you notice the ridge go under the map plane unevenly during your Flood Test, follow these steps (shown in the GIF above):

1. Click on the wrench icon to the right of the De-Tilt model option within the 3D model properties panel. It will bring up a tooltip to help!

2. Click on two points in the model that are parallel with the ridge of your subject structure.

3. After clicking the second point, click on the Checkmark where the wrench was in the properties panel to submit the de-tilt action.

4. You can de-tilt again by clicking on the wrench again, or undoing the de-tilt by clicking on the circular arrow icon.
