BOSL2 is a large OpenSCAD library providing shapes, masks, attachments, rounding/filleting tools, math utilities, and shorthands to simplify parametric 3D modeling. It requires OpenSCAD 2021.01 or later and is explicitly labeled beta code.
Use cases
- build parametric 3D models in OpenSCAD more easily
- position model parts relative to each other with attachments
- round edges and fillet corners of 3D shapes
- sweep profiles along paths to create complex objects
- subtract mask shapes from object edges
- write shorter, more readable OpenSCAD code with shorthands
When to choose
- you model in OpenSCAD and want easier positioning and composition of parts
- you need rounding, filleting, or edge masks that are hard in native OpenSCAD
- you want a comprehensive toolkit of shapes, transforms, and math helpers for CAD scripting
When to avoid
- you use BOSLv1 code, which is incompatible with BOSL2
- you need a stable, non-beta library and cannot tolerate reorganization
- you don't use OpenSCAD or work outside parametric CAD scripting
