A set of miscellaneous tools for FreeCAD. It's not a workbench, it's a collection of loose tools to be included in custom toolbars.
Create a helix that follows a selected path
Select a path and the Path Helix tool. Adjust the helix in the data pane. The helix will always be the full length of it's Spine. Count and Pitch are connected. When one is adjusted in the data pane, the other changes automatically to accomodate.
Given an object containing multiple shapes, extrude each shape individually along its normal. Especially useful for a ShapeString copied into a polar lattice in Lattice2
Create a line normal to a face or a closed edge. A DiscretizedEdge is a special case, in that case, a line normal to the overall shape is made at every sidcrete point. The Angle parameter in the data pane can tilt the line towards/away from the geometric center of the shape.
Lofts from one face to another in the Part workbench. Works more like the loft tool in PartDesign.
Works similar to sub-object shape binder, but selects shape wires by number from the feature it is applied to. Notably, connected lines in a sketch will form a single wire.
Just clone this repository in your FreeCAD/Mod directory, then (re)start FreeCAD.
