PatternMaker vs Seamly2D

PatternMaker is Windows CAD software for viewing, generating, editing, drafting and grading garment patterns. Its maker describes versions for home sewers, professional pattern makers and designers. Pattern macros can generate patterns from body measurements and style selections, while Grading Studio creates graded patterns and lets users save and reuse grading data. The Basic Viewer opens, views and prints pre-made patterns and includes three custom-fit patterns; on Windows-compatible printers or plotters, it can print full-size patterns with alignment marks for multi-page output. Professional Studio can save files as .dxf, and the FAQ says the software supports AutoCAD DXF as well as its own format, which cutting-machine software cannot read. PatternMaker is strictly 2-D CAD, not intended for 3-D fitting or draping. A free Basic Viewer is available. Paid versions listed include Deluxe Editor at 110.00 USD once, Professional Studio at 420.00 USD once, MacroGenerator at 450.00 USD once and Grading Studio at 1250.00 USD once. The FAQ says only CAD tools programs have a 30-day limit; free patterns can remain on the user's computer indefinitely.

Seamly2D is free, open-source fashion design software for creating garment patterns on Windows, Linux, and MacOS. Its pattern workflow supports adapting earlier designs and working with size charts, made-to-measure data, and converted body scans. The site lists apparel, costumes, athletic wear, pet gear, outdoor products, and upholstery as possible applications. Seamly describes a process extending from design through manufacturing for physical and digital products, and says its software integrates 2D, 3D, and Mixed Reality. A beta process described for 3DLOOK MOBILE TAILOR measurements converts CSV files into Seamly measurement files by email. The download process asks for a name, email, operating system, and intended use before emailing a download link. The download page says Seamly Systems does not sell or share the personal information it holds. A user forum is available for software discussion. Seamly2D includes 2D pattern making and size grading, with SVG listed as an export format.
