ERGOMODELS digital sewing patterns in PDF format are specially designed for use with a projector.
Each file is prepared true-to-scale (1:1) with a working width of 80–90 cm and includes a 5×5 cm calibration grid — the key element that ensures perfect accuracy during setup and cutting.
After purchase, the files are available instantly, so you can start working right away — no printing, taping, or paper waste.
It’s a step toward a more eco-friendly, precise, and modern cutting process.
Advantages of Projector Cutting
· 100 % paper and ink savings.
All patterns are stored digitally — no more stacks or rolls of paper.
· Order and free workspace.
Your cutting table stays clear — no need to store printed patterns.
· Instant access.
Once purchased, the file can be opened and used an unlimited number of times.
· High cutting precision.
The 5×5 cm grid helps verify scale and guarantees perfect 1:1 accuracy.
What You’ll Need
· A projector (ceiling-mounted or portable) connected to a tablet or computer.
· A cutting table with a printed grid of squares (calibration grid) measuring at least 0.90 × 1.20 m.
· Pattern weights to hold the fabric in place.
· A rotary cutter (or scissors) suitable for your fabric type — for clean, fast cuts.
How to Open PDF Patterns for Projector
For accurate display, use Adobe Acrobat Reader.
Open the file and select “Actual Size” — this preserves the true 1:1 scale.
For convenience, enable full-screen mode (Ctrl + L) — the image will remain clean and stable during projection.
How to Set Up
1. Connect the projector to your tablet or laptop.
2. Using the projector’s menu, align the image:
– all four corners must be at 90°;
– grid lines on the projection must run parallel to the printed grid on your table.
3. Open the ERGOMODELS PDF pattern file and project it onto your cutting surface.
4. Check the scale: the projected 5×5 cm grid should exactly match the grid on the table surface.
5. Once calibrated, the image remains stable — re-calibration is unnecessary unless the projector is moved.
Tip: periodically verify the scale for consistent precision.
6. ⚙️ If you change the position, height, or angle of the projector, a new calibration is required to restore perfect scale accuracy.
Installation Recommendations
For best results, mount the projector permanently — on the ceiling or on a stand along the long side of the table — so the projection fully covers the working area.
This keeps the image sharp and uniform across the surface, and your settings remain consistent between sessions.
Lighting also matters: a soft side light works perfectly — the projected lines stay clear, and the fabric remains visible.
Practical Notes
Every technology has its nuances, and projector cutting is no exception.
1. Small pattern pieces.
For elements where millimetric accuracy is essential — collars, pocket flaps, cuffs — it’s best to trace outlines with tailor’s chalk, using a measuring tape for control.
This ensures ideal symmetry and precision, even in the smallest details.
2. Projection field size.
A standard projection area of 80×140 cm may limit very large pieces.
In projector cutting, the pattern stays static, while the fabric is moved.
It may feel unfamiliar at first, but after several sessions it becomes natural: the fabric glides smoothly, the image stays steady, and accuracy is maintained.
3. Flexible workflow.
Because the fabric can be repositioned, each piece can be adjusted individually — for example, to increase seam allowance, adjust length, or refine shape directly during cutting.
Fabric Handling Tips
Projector cutting can be done either with fabric folded in half (for mirrored pieces like sleeves or fronts) or flat, cutting one piece at a time.
The main requirement is to maintain grainline direction for every layout.
To prevent grain distortion, use this simple method:
1. Before cutting, draw one or several control lines parallel to the selvage.
2. Align each new piece’s grainline with this reference line.
3. After cutting, make sure the grainline mark remains visible on the fabric — it will help align the next piece accurately.
4. Cutting becomes easier if the fabric is secured on both sides of the cutting area using metal bars, flat stones, or pattern weights.
5. Before removing the weights, remember to mark notches at key points.
Summary
Projector cutting means precision, speed, and order.
It’s ideal for small ateliers, design studios, and home sewists who value technology and accuracy.
ERGOMODELS PDF 1:1 digital sewing patterns unite craftsmanship with innovation — enabling a clean, efficient, and paper-free workflow.
