LaserBurn Object Management: Combine/Split and Layer Lock

Introduction

To improve editing efficiency and operational safety, the software provides two core features: Combine/split and layer lock/unlock.

The Combine/Split function allows multiple independent objects to be temporarily grouped into a single entity for unified operations or separated back into their original objects when needed. This is primarily used for batch transformations such as moving, scaling, and alignment.

The Layer Lock/Unlock function prevents accidental selection, modification, or deletion of objects on a specific layer while keeping the layer visible. It is typically used to protect completed backgrounds or reference content.

Both features use clear icons, explicit command names, and state-based dynamic interactions to ensure predictable behavior and reduce user error, especially in complex editing scenarios.

Function 1: Combine/Split

The purpose of this function is to temporarily bind multiple independent objects into a whole for operation or to disassemble the whole back into independent objects.

1. Icon and Text Design

• Combined icons: Icons that use two or more geometric shapes connected together.

• Split icons: Icons that use a graphic made up of multiple parts, with a clear visual cue of separation.

2. Directly use "Group" and "Split."

• Group: Combines selected objects into a single unit, making them easier to move and transform simultaneously.

• Split: Splits a grouped object into its original, independent objects.

3. Dynamic and Interactive Feedback

• Top-left menu: Right-click on a selected object to dynamically display menu items based on the selected object's status.

  • When multiple independent objects are selected, the menu displays "Combine."

  • When a grouped object is selected, the menu displays "Split."

• Changes after executing the command:

  • After executing "Combine," the control points of the selected objects disappear and are replaced by a unified control box.

  • After executing "Split," the unified control box disappears, and each sub-object's control points reappear.

• New User Guide: When the software is first launched or when entering the drawing module, a brief reminder card indicates that multiple objects can be "combined" for easier unified management.

Function 2: Layer Lock/Unlock

This feature prevents any accidental editing (selection, moving, deletion) of all objects on a specific layer while still maintaining their visibility and is commonly used to protect completed backgrounds or reference drawings.

1. Icon and Text Design

• Lock icon: Uses the classic closed lock icon. This is the universal lock/unlock symbol.

• Unlock icon: Uses the open lock icon.

2. Button/Menu Text

• Lock Layer: Locks the layer, preventing its contents from being selected or modified.

• Unlock Layer: Unlocks the layer, allowing its contents to be edited.

3. Dynamic and Interactive Feedback

• On-canvas behavior limitations: When a user attempts to click, select, or drag an object on a locked layer, no action is taken.
