Align a SCENE Scan Project Using the Two or Three-Point Project Alignment Tools
Overview
The Project Alignment Dashboard introduced in SCENE 2020, provides you with tools that enable you to change global coordinates in your project. Use these tools after you have processed and registered all your project scans. Project alignment tasks are often helpful when you want to export your project for use with other data, and you want to ensure that the exported data matches the coordinate system of the data you want to use with it.
All changes that you make are immediately applied to the project. As long as you have the dashboard open, you can undo the changes that you make during that dashboard session. After leaving the dashboard, the changes can only be undone by rolling back to a previously saved version of the project.
Access the Project Alignment Tools
After the project has been registered, you will be promoted to change global coordinates. Click on “Continue with Project Alignment” to create a new project alignment.
Alternatively, you can access the Project Alignment Tools from the Registration Tab as shown below:
You may then create a new global coordinate based on either a two point or three point alignment.
Two Point Alignment
Use the two-point alignment tool to change the origin position or the orientation of your project's coordinate system while preserving the level. You can select an existing scan point to serve as the origin, or establish the desired coordinates for the selected point. You need to type the coordinates in the text boxes.
To use the two-point alignment tool:
- Select a point that should serve as the new origin.
- If the desired coordinates for the selected point are different than 0,0,0, please enter the X, Y and Z values for the point. Once the transformation is applied, those values will be the coordinates of the selected point.
- Select another point. This point defines the direction of the an axis- The second axis will be perpendicular to the first axis.

Three Point Alignment
Use the three point alignment tool to change the origin position and/or the orientation of your project's coordinate system. You can select an existing scan point to serve as the origin, or establish the desired coordinates for the selected point. You need to type the coordinates in the text boxes. To use the three point alignment tool:
- Select a point that should serve as the new origin, or a point that is close to where the new origin will be.
- If the desired coordinates for the selected point are different than 0,0,0, please enter the X, Y and Z values for the point. Once the transformation is applied, those values will be the coordinates of the selected point.
- Select a point to define direction of the the first axis.
- Select another point. This point defines the direction of the second axis.
- The three points selected will form a plane / level of this project. Only use the 3 point alignment if you will not be using the inclinometer for the project.
