RoamCAD

RoamCAD is a free CAD solution that runs offline on low-spec machines, focusing on modest memory usage. It offers standard extrude, revolve, loft, fillet, and array features. A “sketch dimension lock” ensures 2D profiles remain consistent. RoamCAD’s file manager versioning system keeps older saves. Export options include 2D DXF or 3D STL. With minimal hardware requirements, RoamCAD is ideal for small businesses or individuals on older laptops wanting a stable environment for basic 3D part creation without draining system resources.
