I've been sketching floor plans for years and always dreaded drawing perfect circles freehand—this thing nails it. The way the aperture moves smoothly to tighten the radius from 3 to 70mm is oddly satisfying, and it makes shading quick work. My straight lines finally have a matching circle to go wit

The moving aperture from 3 to 70mm makes concentric circles feel effortless—I used it for a shaded site plan and the crisp edges saved me at least an hour of fiddling with compasses. It's become a permanent fixture on my drafting desk.

The adjustable aperture glides so smoothly that switching from a 3mm dot to a 70mm circle takes seconds, and the shaded-circle option is a lifesaver for quick elevation renderings. I’ve used it on three projects this week and haven’t reached for a compass once.
