Procreate does not read SVG — use PNG for it. SVG keeps editable layers for Inkscape, Illustrator and Affinity.

A project file is the only reopenable artifact. Everything stays on your device — nothing is uploaded.

About

Intersecting Parallels — where you stand and what you see.

Draw lines that are bound to vanishing points. Move a point and every line bound to it re-solves, so the drawing stays a coherent construction instead of a set of strokes. Export the outline and finish it wherever you like.

What it is

  • Free, and yours to keep — no account, no sign-up.
  • Everything is stored on this device. Nothing is uploaded, and there is no analytics.
  • Works offline once loaded; add it to your home screen to launch it like an app.
  • It is not a paint app: no brushes, no pressure, no colour. It builds the geometry.

Keyboard

  • Arrow keys nudge a focused vanishing point; Shift makes larger steps.
  • Every point has exact x and y boxes in the Vanishing points panel.
  • Undo and redo are in the toolbar, one step per gesture.

Accessibility

Everything on the canvas is reachable from the panel, because a canvas cannot be tabbed into. If something here is hard to use, that is a bug worth reporting.
