Define UCS

Define UCS is used to set a custom coordinate system for point cloud or model data. In the window, you can determine the coordinate system's origin and the X, Y, Z axes, establishing a transformation matrix. Applying the transformation matrix will change the data's coordinates. If the transformation matrix is not applied, it will reset the current transformation matrix at the end.

Usage Instructions

1. Use the left mouse button to select the origin of the coordinate system on the point cloud or model.
2. Move the mouse to the appropriate position and click the left mouse button to set the X axis of the coordinate system.
3. Move the mouse to the appropriate position and double-click the left mouse button to set the Y and Z axes of the coordinate system.
4. Click "Apply Transformation Matrix" to change the data's coordinates and save to a file.
