Valentina is clothing-pattern software for building and modeling patterns, with an emphasis on parametric sizing. Measurements, increments, formulas, and construction rules can be used to rearrange patterns. It supports 2D pattern making and size grading, and exports SVG, PDF, PNG, OBJ, PS, EPS, and DXF. The software runs on Linux, macOS, and Windows. Stable downloads list an AppImage for Linux, Windows 7+ 32-bit and Windows 10+ 64-bit packages, and macOS packages for Intel, Apple Silicon, and Universal systems.
