DolyaCut

Before you start

• Desktop Google Chrome; tested in Chrome 152 on Linux. Other browsers, operating systems and physical mobile devices are untested.
• Download and extract the purchased ZIP. Keep the manual, screenshots and sample alongside DolyaCut.html.
• Prepare the physical pieces cut for one block, usable fabric widths, block counts and your chosen allowance policy. Measurements must be whole eighths of an inch.

Your first result

1. Open the local application

   Extract DolyaCut-1.0.0.zip, then open DolyaCut.html in desktop Google Chrome. No account, server, internet connection or extra installation is required. Open manual/index.html for the bundled illustrated manual.

2. Run the supplied example

   Choose Load example “Lantern Path”. Results should show a green expected-outcome check for both Baby and Throw. The worked figures below provide an independent reference before entering your own pattern.

3. Describe the fabrics and physical cuts

   On Fabrics, enter unique fabric names and usable widths of 20–120 inches. On Blocks, list the physical pieces cut for one block: fabric, quantity, strip width and subcut length. HST and QST are wording only; they never multiply the quantities. Measurements such as 4 7/8, 4.875 and 4⅞ are accepted.

4. Set layout, sizes and allowances

   On Layout, choose finished block size, sashing with cornerstones, up to three borders, binding, separate backing fabric and batting overhang. On Sizes, make each block count total columns × rows. On Policy, choose no extra, one widest strip or a percentage, then rounding up to ⅛ or ¼ yard. Optional metres are approximate output only.

5. Calculate and resolve problems

   Press Calculate. Any problem links to the field that needs attention. Non-eighth measurements, missing fabrics, incorrect block totals and cuts longer than the usable width are refused. After an edit, results and exports remain unavailable until you calculate again.

6. Check every size

   Review the fabric-by-size matrix, then choose each size to inspect its cutting directions, strip diagrams, leftovers and calculation trace. The policy footnote states usable widths, extra fabric, rounding and join losses. Different cut lengths are not packed together. These figures do not prove that a block can be sewn successfully.

7. Export and print

   On Export, download requirements CSV, cut-list CSV and cutting-direction text. Leave the UTF-8 byte-order-mark option on if your spreadsheet needs it for fractions. Choose Print worksheet / save as PDF; each size begins a new page group and the allowance policy appears on each page. Check the preview before printing.

8. Save before leaving

   Choose Save project file to keep an editable .dolyacut.json copy. There is no automatic browser storage. In a fresh tab, choose Open project file and select that saved project, then Calculate to rebuild the tables. Save before returning to Start page or replacing a pattern; every export is a new download and the original file is unchanged.

A worked example

Lantern Path: a two-size check

Input: Fictional Lantern Path: 8-inch Lantern block cut from two B 2 1/2 x 8 1/2 inch rectangles plus one A and one C 4 7/8 inch HST square; 2-inch A sashing between and around the blocks with C cornerstones; 4-inch B border; 2 1/2-inch C binding with 12 inches extra; D backing and batting with 4-inch overhang; 40-inch usable width; one widest strip extra; rounded up to 1/8 yd. Sizes Baby 4x5 and Throw 6x7.

1. Load the supplied Lantern Path example.
2. Read Results and compare both sizes with the figures below.
3. Export the requirement and cut-list CSVs, then save and reopen the project.

Expected result: Baby 50x60 in: A 1 1/2 yd (47 1/8 + 4 7/8 = 52 in), B 1 5/8 yd, C 1 1/4 yd, backing 3 1/4 yd (2 panels, horizontal seam, 116 in), batting 58x68 in, binding 7 strips, border 6 strips. Throw 70x80 in: A 2 3/4 yd, B 2 5/8 yd, C 1 7/8 yd, backing 5 yd (2 panels, vertical seam, 176 in), batting 78x88 in, binding 9 strips, border 8 strips.

Troubleshooting

Compatibility & limits

• Tested only in Google Chrome 152 on Linux; other browsers and operating systems are untested
• Inches only, in whole eighths; metric input is not supported
• At most 50,000 pieces and 5,000 strips per size; project files up to 2 MiB.
• No on-point settings, setting triangles, applique, templates/EPP/FPP, fat-quarter planning, directional-print matching or lengthwise borders
• Different cut lengths are never packed into shared strips, so yardage is conservative rather than optimal
• Backing must be a fabric used for nothing else
• No physical sewing test was made; figures follow your cut list and stated policy, so test-cut before publishing
