DRAG a chip below onto the board to drop a rail there — or draw one like a pencil by dragging along an empty line. Click a rail to select it · drag its ends to resize · drag the bar to slide (20 mm grid) · click its size label to type an exact length. RIGHT-CLICK a rail for everything else: fill rails, key hooks, duplicate, lock, printed, export, delete.
Every divider bar of the layout as separate printable pieces (long ones split to the print bed). Rails flagged 🪝 (right-click) export with their key hooks.
Removes every hand-drawn/dropped rail and every manual size/slide override, returning to the pure automatic network derived from the pieces. Use it when the rails got messy after heavy rearranging.
Add to board places a real rail on the layout (nearest free line to the centre) — then drag it into place like any rail. Download STL saves one standalone bar instead, without touching the board. Ticked hooks apply to both; flagged layout rails use the same rod/reach values.
Rails print as deep as the piece plates (Plate thickness, Layout menu), so the black bars sit FLUSH with the piece fronts on the wall. Untick to use the custom Rail thickness (Board menu · Advanced) for thin bars instead.
