Construction snapping lets you snap a node's control handle to useful construction angles relative to the adjacent node and opposing control handle. You can also balance control handle lengths on adjacent nodes.

You can enable construction snapping via a single button which permits control handle snapping to various angles and alignments.

Control handle snapping behavior	Example
Snap the leading control handle inline to adjacent node
Snap 90° to inline
Snap to reflected/mirrored angle
Snap to parallel control handle
Snap to 90° from parallel control handle
Snap to logical triangle

These snapping options operate independently of global snapping. They help avoid having to align control handles to grid or guide and offer additional accuracy and symmetry once nodes have been positioned using Curve snapping options.
