Pattern Layout

Drag and rotate the pattern pieces to see how they fit on your fabric roll width. Export to a 1:1 scale svg and edit in Inkscape or similar for finer grained control. The seam line is shown on the svg if you need to combine panels.

Pattern Geometry Data

This is the 'cut line' geometry (side lengths and angles) for each panel, calculated based on the 3D tent shape. This data can be copied for external use

Manual Editor

The `baseCornersRelative` coordinates are relative to the `apexAbsolute` position (e.g., `rel_x: -100` means 100cm to the left of the apex). The visualizer will update when you click away from this text box.
