In the Aholo Editor, you can use the Crop tool to remove unwanted areas or noise, keeping only the essential parts of your model for a cleaner, more focused result.

Enter Crop Mode

  1. Open your project

  2. Click on the model in the scene to bring up the floating toolbar

  3. Click “Crop” to enter crop mode

Choose a Crop Shape

Before adjusting, select the shape of the cropping area:

1. Cube

  • Ideal for spatial scenes

  • Easier to align with architectural structures

2. Cylinder

  • Better suited for single objects

  • Wraps around the subject more naturally

Cube
Cylinder

Adjust the Crop Area

The crop box can be precisely controlled along the X, Y, and Z axes:

1. Move the Crop Area (Position Adjustment)

How to:

  • Drag an axis (X / Y / Z) → move the crop box along that direction (size unchanged)

  • Click an axis → enter an exact distance (e.g., 2 m)

Concept:

  • Think of this as translating the crop box in 3D space

  • The size stays the same; only the position changes

2. Resize the Crop Area (Range Adjustment)

How to:

  • Drag the handles on an axis → adjust the length in that direction

  • Click a handle → enter a scale value (e.g., 2 → doubles the length)

During adjustment, you’ll see two values update:

  • Percentage (e.g., X: 11%)

  • Actual size (e.g., 2.786 m)

Concept:

  • Dragging = manual stretching of the crop box

  • Entering values = precise size control

Choose a Cropping Mode

After adjusting position and size, select how the crop should be applied:

1. Crop Outside

  • Keeps the area inside the crop box

  • Removes everything outside

Best for:

  • Removing background

  • Cleaning edge noise

2. Crop Inside

  • Keeps the area outside the crop box

  • Removes everything inside

Best for:

  • Removing local interference

  • Eliminating unwanted elements in the center

Save & Undo

After finishing your adjustments:

  • Click “×” to exit crop editing

  • Click “✔” to apply the crop

Tips:

  • Before saving, you can click “Undo” to revert the previous step

  • Once saved, the crop cannot be undone—make sure everything looks correct before applying

Best Practices

  • For complex models, use smaller, multiple crops for better precision

  • Leave some margin to avoid over-cropping
