What is Lattice workbench
The workbench purpose is 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 applied.
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 compounds.
One of the big design goals of the workbench is being as parametric as possible.
Installation: download zip, unpack the contents into a "Lattice2" folder created in \Path\to\FreeCAD\Mod, restart FreeCAD
Lattice v1 is deprecated, as Lattice 2 is becoming stable.
