Boolean Assistant: Choose the Geometry Result Visually
Boolean operations depend on shape overlap and selection order; the assistant helps compare possible results before committing.
Lock Shapes to Protect a Finished Layout
Locking prevents accidental movement, resize, rotation or deletion of selected design elements while you continue editing around them.
Select Shapes Smaller Than Selected for Cleanup
This selection tool is useful for cleaning noisy traces/imports or selecting classes of tiny geometry without clicking each object.
Select Circles by Exact Size or Range
LightBurn 2.1 can select circles by exact size or size range, useful for fastener holes and cleanup in complex imported designs.
Nudging Shapes Precisely With the Keyboard
Arrow-key nudging is faster and more repeatable than dragging when you need small positional corrections; modifier keys can change the nudge amount.
Virtual Edits and Symmetric Shape Changes
Virtual-edit style operations can change design behavior without destructively rebuilding every path; understand what remains editable and what becomes final geometry.
Extreme Nodes and Curves That Misbehave
Imported or traced paths can contain extreme control handles or excessive nodes that create spikes, loops or unstable editing.
Trim Shapes: Cutting Vector Geometry Cleanly
Trim removes path portions at intersections without requiring you to manually break every node, but it depends on real path intersections.
Offset Shapes: Borders, Cut Lines and Inset/Outset Geometry
Create new vector contours at a controlled distance for borders, cut outlines and fit-related geometry.
Boolean Tools and Weld: Combine Closed Vectors Intentionally
Use Union, Subtract, Intersection and Weld for real geometry construction rather than stacking overlapping shapes and hoping Fill interprets them correctly.
Edit Nodes: Repair and Reshape Vector Paths Precisely
Use nodes, segments and curve handles for local vector repair instead of redrawing an entire imported or traced shape.
