Editing Models

Tools for editing and selecting model content.

Entry: Menu bar → Edit, or the quick action bar

Undo and Redo

Note: A new action clears the redo stack. When there's nothing to undo or redo, the button greys out.

Delete

Select a model or selection, then press Delete or click Delete. Cropping doesn't change the original data — afterward you can save the result as a new model, keeping the original intact.

• Deleting a model needs a second confirmation
• Deleting a selection runs immediately

Add to Selection

With any selection mode active, hold Shift and make a new selection. Objects in the new region join the current selection.

Add to selection

Use cases:

• Selecting objects across several separate regions
• Catching content you missed in an initial selection
• Combining different selection tools for a complex selection

Subtract from Selection

Hold Ctrl and make a new selection. Already-selected objects in the new region are deselected.

Subtract from selection

Use cases:

• Removing a local region after a broad selection
• Refining a complex selection alongside Add to selection
• Controlling the final crop range to avoid removing content you want to keep

Invert Selection

Press Ctrl + I to toggle between "inside the box" and "outside the box."

Invert selection

Use cases:

• Selecting everything outside a region
• Clearing regular regions or quickly excluding areas in large scenes

Separate

Separates the selected content from the original model as a new, independent model.

How to use: Select a target region → press Ctrl + Shift + D or click Separate

Separate operation

Use cases:

• Extracting standalone objects (furniture, equipment) from the whole model
• Color grading or transforming a local region on its own

Clone

Copies the selected content as a new, independent model. The original is unchanged.

How to use: Select a target region → press Ctrl + D or click Clone

Clone operation

Use cases:

• Experimenting on a copy while keeping the original data
• Duplicating a region to compare color grading

Move / Rotate / Scale

Select a model, then switch edit type in the toolbar:

• The three tools are mutually exclusive; only one is active at a time
• When active, the matching gizmo appears at the model's center
• Supports batch operations on multiple selected models
