Cropping keeps or removes a specified region of a model. Cropping does not modify the source file. After cropping, select File → Export → Export Model to create a new model file.

How to Use

4. Set the crop mode and keep option as needed.
5. Preview the result and confirm the crop.
6. Select File → Export → Export Model to save the processed model.

Crop Tool Options

• Box: Uses a box to define the spatial range.
• Razor: Cuts the model according to the crop box.
• Keep Inside: Keeps the content inside the crop box.
• Scale Gizmo: Uses the Scale Gizmo to resize the crop box.
• Show Box: Shows or hides the crop box.
• Box Color: Changes the display color of the crop box.
• Depth Occlusion: Controls depth occlusion while the crop box is displayed.

Notes

• Adjust the crop box and perform cropping in Edit mode.
• Locked models cannot be crop targets.
• To keep the original model after cropping, save a copy of the project first, then export a new model file.
• If the result is not as expected, use Undo to restore the state before cropping.

Three-Point Alignment

Three-Point Alignment uses three points selected on a model surface to create a reference plane and adjust the model orientation.

2. Click Three-Point Alignment in the top editing toolbar.
3. Click three points on the model surface in sequence to create the reference plane.

5. Select the direction to which the reference plane should align:
   • XY: Aligns the reference plane with the XY plane.
   • XZ: Aligns the reference plane with the XZ plane.
   • YZ: Aligns the reference plane with the YZ plane.
6. Enable Align to Origin if you want to move the center of the reference plane to the world origin.
