FreeCAD

To fuse solids together it is better to have overlapping solids.

Part Design Workbench

Part Design modelling has a sequential workflow, the operations are piled one after another (except for sketches which are nested inside their operation).

Sketches are automatically hidden after use in an operation.

The PartDesign workbench uses a parametric, feature editing methodology, which means a basic solid is sequentially transformed by adding features on top until the final shape is obtained.

[…]

The PartDesign Workbench is intrinsically related to the Sketcher Workbench. The user normally creates a Sketch, then uses the PartDesign Pad tool to extrude it and create a basic solid, and then this solid is further modified.

Part Workbench

Part modelling has a hierarchal workflow where instances are nested into each other after operations.

Sketches are not hidden after use in an operation.

The Part Workbench is based on a constructive solid geometry (CSG) methodology for building shapes.

FreeCAD wiki

A useful tool to inspect how many solids compose a single document.

The dependency graph depends on the GraphViz library.

On major linux distribs you can simply install graphviz from the repos :

$ sudo apt install graphviz

If FreeCAD signals that it cannot find the GraphViz package when you are sure it is installed, you can correct this by pointing it to /usr/bin/ with the appropriate dialog box.

Create a shape to be grooved (Sketch + Pad) groove1.jpg
Create another sketch along the correct axis and create a closed shape to mark the groove groove2.jpg
Select the first shape and the sketch and apply a groove along the corresponding axis (here Z) groove3.jpg
