FuCad 26.3.0 is the first FuCad release meant to be used rather than tried.
Everything before it was either a tag inherited from the upstream fork or a
weekly development build.
FuCad keeps FreeCAD's geometry kernel, document model, Python API and .FCStd
format, and reworks the experience along the lines of Fusion 360. This release
is where that rework becomes usable end to end.
The shell
The app bar is now the window's title bar: one row carrying the menu, the quick
access buttons, the document name, the workspace selector and the window
controls, with no system caption above it. Dragging it moves the window and
dragging an edge resizes it, both handed to the window system so snapping still
works. Safe mode keeps the system frame.
S opens a command palette at the cursor with the commands you pinned, the
ones you ran last, and a search over everything the application has registered.
Right-click in the 3D view opens a marking menu: the entries sit around the
cursor instead of below it, so reaching one is a direction rather than a
distance. Its content follows the selection, and the middle of the ring names
what the menu is about.
A navigation bar floats over the bottom of every 3D view with fitting, the
standard views, the draw style and the projection.
Selection filters in the SELECT panel say which kinds of geometry a click is
allowed to find, so a crowded model stops fighting the cursor.
Task dialogs put OK and Cancel at the trailing edge with a tick and a cross, and
the overlay panel headers lost the two toggles that made them read as machinery.
Modelling
Three direct edit tools change a solid by acting on its faces rather than on
the feature that made them, which is the only way to edit a shape that arrived
through STEP: Offset Face pushes faces along their own normal, Move Face
carries them along a direction you choose, and Delete Face takes them out and
closes the solid over the gap.
Press/Pull on Q is one key for the three tools reached for most: a
profile extrudes, an edge fillets, a face offsets, and nothing selected opens the
face tool ready to pick.
Dragging the extrude arrow through the profile now turns the operation
around, so pushing past zero starts cutting instead of stopping.
Sketching
A status badge floats over the canvas while a sketch is open, saying how
constrained it is in a colour: green when finished, amber while it is not, red
when the solver cannot make sense of it.
Keyboard
The tools take the letters Fusion reaches them by. E extrude, F fillet,
H hole, M move, I measure, A appearance, Q press/pull, S
palette. In a sketch: L line, R rectangle, C circle, D dimension,
T trim, O offset, P project, X construction. The five sketch
constraints that held those letters moved into the K prefix the other
dimensions already use.
Workspaces
DRAWING, MANUFACTURE and SIMULATION join the ribbon with panels named
and grouped the way the rest of the application is, instead of the generated tabs
TechDraw, CAM and FEM used to get.
