 ### Geometry Processing
 - **Get Mesh**: Converts a Blender Object into internal `SlicingObject` format.
+- **Transform Geometry**: Moves, rotates, and scales a `SlicingCollection` or `SlicingGroup` relative to the origin.
+    - **Mesh**: Input mesh data.
+    - **Translation**: 3D vector specifying the translation offset.
+    - **Rotation**: 3D vector/Euler rotation values.
+    - **Scale**: 3D vector specifying scaling factors along the X, Y, and Z axes (defaults to `1.0, 1.0, 1.0`).
 - **Get Paths**: Extracts existing edges from a mesh as paths.
     - **Extrusion Multiplier Attribute**: Mesh attribute to use for per-segment extrusion rates.
     - **Feedrate Attribute**: Mesh attribute to use for per-segment feedrates.
