Modify Tools

Basic modify tools

• Move — translate selected geometry.
• Rotate — rotate selected geometry around a point.
• Scale — scale selected geometry.
• Trim/Extend — trim or extend lines/polylines to a boundary.
• Offset — create a parallel copy of a line or polyline at a fixed distance.

Transform gizmo

Press W to activate the transform gizmo on the current selection: a drag-based move/rotate handle with snapping, angle snap, and a relocatable pivot point. This is the fastest way to reposition or reorient a group of geometry interactively.

Explode

Press B to break compound geometry into simpler components — polygons become polylines, polylines become individual lines.

Vertex editing

Add, remove, and modify individual vertices on polylines and polygons directly, without recreating the geometry.

Undo/redo

Every modify operation is recorded in the operation history and fully reversible with Ctrl+Z / Ctrl+Y. See Operation System.
