Overview and Interface
Product Overview
LCC Model Editor is a low-level editing tool for 3DGS models. It provides tools for selecting, cropping, separating, cloning, and color grading model content.
How to open:
- From LCC Scene Editor, click the Model Editing button.
- Launch the standalone application. It opens in View mode by default.
Two modes:
- View mode: Supports browsing and measurement only. The Properties panel is read-only.
- Edit mode: Supports all editing functions. Models cannot be imported after you enter this mode.
Interface Layout
The interface has three main regions: top, left, and right.
| Region | Contents |
|---|---|
| Top — Menu bar | File, Edit, View, Settings, Help |
| Top — Quick action bar | Save, Open, Undo, Redo, view switching, projection mode switching, and selection mode switching |
| Left — Toolbar | Edit tools (Move / Rotate / Scale), selectors, measurement tools, application tools (Three-Point Alignment), and color grading tools |
| Right — Asset list | Model file management |
| Right — Properties panel | Properties for the selected asset |

Camera Projection
Projection Modes
LCC Model Editor supports Perspective Projection and Orthographic Projection. You can switch between them in View mode and Edit mode.
Camera Projection menu
Perspective Projection
Orthographic Projection
- Perspective Projection (default): Objects closer to the camera appear larger and distant objects appear smaller. It is suitable for natural model browsing.
- Orthographic Projection: Objects do not appear larger or smaller based on distance, and parallel lines remain parallel. It is suitable for front, side, and top views, as well as model alignment and measurement.
To switch: From the top menu bar, select View > Camera Projection, then choose Perspective Projection or Orthographic Projection.
Switching projection modes does not change model data or the current camera position and orientation. In Orthographic Projection, scrolling changes the visible range rather than moving the camera.
Edit Mode and View Mode
Entering Edit mode
- Click Edit Mode.
- Confirm that you want to enter. Models cannot be imported after you enter Edit mode.
Exiting Edit mode
- If the project is saved and there are no new edits, the editor exits directly to View mode.
- If there are unsaved edits, the system asks whether to save. You can save, discard, or cancel.
