The artwork SVG keeps text editable and includes a magenta CutContour layer, the spot name most print-and-cut software looks for. The cut-line SVG holds only the outlines, for Cricut or Silhouette. Both are sized in real inches.
Each line starts where the one above ends. Angle at end is the inside angle between that line and the next one, like an angle dimension in Fusion 360. Over 180° makes an inward notch. A closing line back to the start is added for you. Curve bows a line into an arc by that height: positive bows out, negative bows in. Leave a fillet blank to use the all-corners value. Corners next to a curved line stay sharp.
Drag a corner or a line to move it. Directions snap to 15° steps, so horizontal, vertical and 45° lines are easy to hit. Hold Alt to move freely. Typed values apply when you press Enter or Tab.
