Part3D review
Affordable Apple-device CAD with practical parametric tools for 3D printing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Part3D is a CAD and 3D modeling application for iPad and macOS, aimed at hobbyists, makers, and 3D-printing enthusiasts. Its workflow combines parametric 2D sketching with constraints and dimensions, feature-based solid modeling, and non-destructive feature tree editing. Modeling tools include extrude, revolve, fillet, and chamfer, while Part3D Bridge supports direct transfer to Orca Slicer, Bambu Studio, and Creality Print. The application operates offline and on-device, making it a focused option for Apple users who want to create printable parts without relying on a browser-based workflow.
The feature set is strongest around practical part design and print preparation. Users can work with constrained sketches, build solids from those sketches, revise features through the tree, and exchange CAD files through STEP import and export. STL and OBJ export support printing workflows, with high-quality export listed for Pro Lifetime. The Free plan includes basic sketching tools, extrude, fillet, chamfer, Part3D Bridge support, and regular-quality STL and OBJ export. This makes the free tier suitable for simpler projects, while more demanding CAD exchange and export requirements point toward a paid plan.
Published plans show Free access, Pro Monthly at $5.99 per month, Pro Yearly at $39.99 per year, and Pro Lifetime at $69.99 one time. The paid plans add all features and an iPad and macOS Beta license; Pro Lifetime also lists unlimited projects, STEP import and export, and high-quality STL and OBJ export. Part3D is a sensible pick for Apple-device makers who value offline parametric modeling and slicer transfer. It is less suitable for users who need Windows, broader platform access, or a wider feature set than this focused 3D-printing workflow provides.
