The Perspective Selection tool shows the selection's bounding box in perspective; its handles scale in plane space (perspective.transform; Shift proportional, Alt from the centre). Alt-drag moves copies that stay attached, pressing 5 while dragging moves along the plane's normal (ToolKey::Digit, delivered by the canvas and MCP press_key), and the arrow keys nudge in perspective (perspective.nudge). Transform Again repeats the last perspective move or scale in plane space. Attachments (plane and depth) now live on the objects (Node.perspective), so copies, duplicates and pastes keep them; grids from older files hand theirs over. Homography moves to vectorcraft-geom. Hint-bar text for the tool. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
