Independent digital drill drawing with your own screen RGB colors. It does not supply adhesive canvas, a calibrated drill-vendor palette or automatic DMC matching. Example spacing is not a manufacturer specification; choose measured basis only for dimensions you have actually measured.
Drafts, geometry, allowance, colors and twenty undo/redo edits are saved only in this browser, separately from Studio and photo conversion projects. Download editable JSON as an independent backup.
This is genuinely blank: no example or drill has been placed. Editable project JSON is available now. Draw at least one cell before exporting a placement chart or material list.
Choose a color and draw. Arrows move the cursor; Enter applies the tool; Backspace empties a cell. Ctrl/Cmd+Z undoes; Shift+Z redoes. One completed stroke is one edit; a second pointer cancels an uncommitted stroke. Pan allows native scrolling. Dark grid lines mark every ten chart cells, not physical board divisions.
1–32 distinct codes, at most 32 characters each: letters, marks, numbers, spaces, dots, underscores or hyphens. Case and canonically equivalent Unicode do not create distinct codes. Opaque #RRGGBB only. Code/RGB changes are undoable. A used color cannot be deleted; replace or empty its cells first. Codes are user labels, not verified brand identities.
Round · 2.6 mm · 2.8×2.8 mm · Nominal example — not measured · 5% · Minimum spare per used color: 2
Drills must fit both cell pitches. Size/pitch accept up to three decimals; spare percentage accepts up to two. Values change the plan only after Apply, not while typing. Geometry and allowance are saved but are outside paint undo history.
Spare quantities are your allowance, not a promise of loss or fit. Counts are placed + max(rounded-up percentage, minimum per used color). Empty cells require no drill. No vendor stock or physical canvas is supplied.
