Choose your editor, make a first edit, and learn how structures, parametric CSG fittings, and purchased parts work together.

Choose your editor

Design an assembly, author parametric CSG fittings, or edit a purchased part’s mate interfaces.

Frame Editor with a 2207 brushless motor mated to a Through-Hole Motor Mount in an assembly. Frame Editor Design the structure. Connect nodes and links, choose stock members, and assemble printable joints with purchased components. Reactive dimensions keep the structure editable as the design changes. Learn the workflow Attachment Editor showing the Through-Hole Motor Mount and its expanded CSG operations, transforms, repeat, and reusable subparts. Attachment Editor Build parametric CSG parts. Author constructive solid geometry (CSG) from primitives, Boolean operations, and transforms. Drive dimensions with parameters and expressions, then reuse the resulting joints, mounts, and fittings across frames. Learn the workflow Foreign Part Editor with a 2207 motor’s 16 mm four-hole flange site selected and its four M3 mounting features highlighted. Foreign Part Editor Define how purchased parts mate. Import a component’s GLB mesh and author its mate interfaces. Edit mounting sites, typed features, dimensions, and local poses so motors, rails, and hardware align with compatible parts in your assembly. Learn the workflow

Build something

Practice an edit, assemble purchased parts, or author a reusable component.

Build something Resize a pull-up bar Change one named dimension, inspect the result, and restore the original. Try the worked example Build something Mate a carriage to a linear rail Place purchased parts, adjust travel, and see the assembly follow its owner. Try assembly mating Build something Add your own purchased parts Import a GLB, define mounting points and keep-outs, and reuse the component in Frames. Use the Foreign Part Editor
