Pen Tool

The pen tool creates vector paths using a vector network data model, compatible with Figma's .fig format.

Activating

Press P to activate the pen tool.

Placing Points

• Click to place a corner point (straight-line segment)
• Click + drag to place a curve point with bezier tangent handles — the drag direction and length control the curve shape
  • Hold Space while dragging (without releasing the mouse button) to move the point itself

Click multiple points to build a path segment by segment. A preview line extends from the last placed point to your cursor as you move.

Closing a Path

Click on the first point of the path to close it into a loop. Closed paths can be filled.

Open Paths

Press Escape to commit the current path as an open path. Open paths render as strokes only — they're not filled.

Vector Networks

Paths in OpenPencil use vector networks — a more flexible model than simple point lists that supports branching paths and complex topology. This is the same model Figma uses, so paths round-trip perfectly in .fig files.

Tips

• The preview line always starts from the last placed point — it won't jump to (0,0).
• Drag longer when placing a curve point to make the curve wider.
• After creating a path, use the properties panel to adjust its fill, stroke, and effects.
