The FreeCAD Lattice2 External Workbench Icon


Lattice2 is stable. New features may be added, but no breaking changes are supposed to happen.

The Lattice2 Workbench is a FreeCAD external workbench that serves the purpose of working with placements and arrays of placements. It is a sort of Assembly workbench, but with emphasis on arrays. There are no constraints and relations, there are just arrays of placements that can be generated, combined, transformed, superimposed, and populated with shapes.

Ever wondered how to create a protractor with FreeCAD? That's the aim of the workbench (including tick labeling). Also, exploded assemblies can be made with the workbench.

Additionally, the workbench features a few general-purpose tools, such as parametric downgrade, bounding boxes, shape info tool, and tools for working with collections of shapes (compounds).

One of the big design goals of the workbench is being as parametric as possible.
