Thanks for letting me know. I can’t directly operate the Flux UI, so here’s a quick way you can confirm and set the outline yourself right now:
Option A — Set exact size numerically
- Go to PCB view (2D).
- Click the board outline to select it (the rectangle itself).
- In the Inspect panel, find Width and Height.
- Enter Width = 70 mm, Height = 50 mm.
Option B — Drag to size with snap
- Select the board outline.
- Drag a corner; hold Shift to constrain if needed.
- Watch the Width/Height readouts in the Inspect panel and release at 70 mm × 50 mm.
Quick check
- Zoom to fit and reselect the outline—the Inspect panel should show Width 70.00 mm, Height 50.00 mm.
If you want, tell me what values you see in the Inspect panel right now and I’ll guide the exact adjustment step-by-step.
