Text on Arc

At a glance

  • Right-click any text group → Text on Arc…
  • Curves text along any arc or circle already in the sketch
  • Controls: radius, center, start angle, inside or outside baseline
  • Each character is individually repositioned — glyph geometry is never distorted
  • Perfect for curved part labels, ring engravings, and logo work

Right-click any text group in a sketch and choose Text on Arc… to curve the string around an arc or circle. Each character is rigidly rotated and repositioned onto the arc — the glyph outlines themselves are never bent or stretched, so the geometry you cut is exactly what the font drew.

Setting the arc

The dialog opens with a sensible starting arc — centered below the text, radius 1.5× the text width, string centered at the top — and the blue preview updates live as you adjust:

  • Pick Arc/Circle — hover an existing arc or circle in the sketch and click; its radius and center copy straight in. This is the move for wrapping a label around a bolt circle or ring you've already drawn.
  • Radius and Center X/Y — or type exact values instead.
  • Start Angle (°) — where the middle of the string sits on the circle; 90° is the top.
  • Baseline outside arc — checked, the characters stand on the outside of the arc and read across the top; unchecked, the baseline sits inside for text that reads around the bottom of a ring.

How characters land

Each character's advance width is unrolled along the circumference, so letter spacing is preserved exactly as the font intended — tight radii fan the letters naturally instead of squashing them. Because the tool needs per-character anchor metadata, it works on groups placed by the Text tool; Apply commits the move and updates those anchors to their new positions.
