Digitizing is not the same as drafting in CAD
What you are trying to accomplish
Understand what PatternForge is designed to do so you can trust the guided workflow and recognize when a patternmaking decision still belongs to you.
Why it matters
Digitizing turns an existing physical pattern into clean digital information. Drafting creates or substantially changes the pattern itself. General CAD software exposes many construction commands because it must support almost any drawing task. PatternForge instead keeps the everyday path focused on capturing, tracing, describing, checking, and exporting sewing patterns.
This distinction prevents a dangerous assumption: a clean digital outline is not automatically a well-fitting or production-ready pattern.
Step by step
- Begin with a pattern source whose shape and intended use you understand.
- Capture or import that source at a verifiable scale.
- Trace the piece and clean only the geometry needed to represent the source faithfully.
- Add the sewing information that belongs to the piece.
- Use Pattern Check to find missing or contradictory digital information.
- Fit-test or construction-test the pattern when the underlying design has changed.
Advanced drawing, measuring, resizing, and seam-relationship tools are available when needed, but they do not replace patternmaking judgment.
What success looks like
You can explain whether you are copying an existing pattern, correcting a digitizing error, or intentionally altering the design. You do not treat automatic detection, smooth curves, or a successful export as proof of fit.
Common problems and recovery
- Trying to design before scale is trustworthy: return to Set & Check Size first.
- Using Resize as grading: stop and create a separate reviewed grading plan. Sizes are not uniform enlargements.
- Assuming Auto-Detect understood the pattern: compare every suggested outline with the source.
- Advanced controls feel overwhelming: close the Advanced section and return to the workflow ribbon.
Quick safety check
Ask, “Am I faithfully digitizing known information, or am I making a new patternmaking decision?” Treat the second case as a design change that needs its own validation.
