- DisplayMesh::from_model_hiding leaves out a hidden body's elements (and the
nodes only they use); Session::hidden_elements names them, so the viewport,
probing and headless pictures skip hidden bodies (#365).
- A solve summary's applied and reaction totals set the round-off of
cancelling sums to 0 (#319).
- results::principal for the probe's principal stresses (#329).

- Quantity names the unit of every number the results show from the model's
unit system (mm, MPa, N, N·mm, mJ, mW, °C or K); Field::title puts it in the
legend title, and calls a mode shape normalised (#321).
- A solved step's result stays current through edits that leave what it reads
alone (Model::step_inputs: other steps and what only they use), and comes
back current on undo (#318).
- Session::step_glyphs: the symbols of what a solved step used, for drawing
over its results; no load arrows on a frequency step's modes (#327).
- Nonlinear static steps open deformed at true scale like explicit ones, and
their automatic scale is 1 (auto_scale, shared by the viewport and the
headless pictures) (#326).
- results.reactions with an empty sets list sums the step's boundary-condition
sets, as its form says (#328).

A datum plane is drawn as the model's extent within it (where it cuts the
model's box, in the plane's axes) plus a 5 % margin, a datum axis along the
model's extent plus the margin, instead of squares 1.2 diagonals wide.
Fit, Home, the standard views and headless pictures frame the model
without the datums (they stay inside the clipping radius). The datum
selected in the browser is drawn highlighted and on top, even when hidden.

Right-click on any browser item (body, surface, datum, partition, set,
material, section, step, boundary condition, load, reference point,
coupling, contact, fluid domain) opens its menu: Edit…, Hide/Show,
Isolate, Show All, Active in step (boundary conditions and loads) and
Delete…. A right click on a datum or a partition's cut face in the
viewport opens the same menu. Each item the viewport draws on its own
has an eye; hidden items are neither drawn nor picked. Datums and
partitions are selectable with properties. Delete… and the Delete key
ask first (the prompt lists what uses the item: a datum's partitions
are deleted with it, other definitions in use are refused); ui.prompt
answers it. Every entry runs the same command as the ribbon and forms.

view.hide, view.show, view.isolate and view.show_all change which
bodies, surfaces, datums, boundary conditions, loads, reference points
and couplings the viewport draws. The hidden items are view state: the
manifest's `view` keeps them, a change marks the model unsaved, but it
is neither journalled nor undone and leaves results current. Items that
go away are forgotten. Headless pictures leave hidden items out; the
glyph builders take a filter. Tools > View > Show All claims the
commands.

Boundary condition, load and interaction symbols are wireframes (thin lines,
no shaded cones), so they never hide the mesh or a contour plot:
- a crossed wire triangle per constrained translation, tip on the node,
coming from outside the part where the set's faces say which side that is;
a held rotation adds a smaller triangle behind it (the double mark); fixed
shows all three axes, a symmetry plane only its normal;
- forces as open-headed arrows ending on the node, as long as four support
units at one place and 2.5 over a set, so loads and supports stay in
proportion (#78); moments as an axis line and a right-handed curved arrow
(#79); contact and tie surfaces as small squares on their faces;
- a constant size on screen at any zoom (#80): the symbol unit is the size
setting (View > Symbol size, `ui.set {symbol_size}`, 14 pt by default)
times the model length a pixel spans, rounded to a quarter of a doubling;
- spread evenly on a grid a few symbol units across, so their density follows
the screen, never more than 400 per definition;
- a layer of their own on the desktop (GPU and CPU): zooming rebuilds and
uploads the symbols only, never the mesh's scene; framing leaves them out;
- colour per kind from the theme's tokens (a new contact colour), and the
definition selected in the browser drawn in the selection colour, wider;
- depth-tested against the model with the line bias that keeps them on their
own surface; a load at a reference point or a single node and a reference
point's cross are drawn over the part (#78).
Headless pictures (MCP screenshot, `ui.render`) frame the camera first and
draw the symbols at the default size for it.

The first look at a solved static step draws the von Mises contours on the
true geometry; the deformed shape comes when asked for (Deformed,
results.deformed, results.animate), at the automatic scale. Frequency steps
still open on mode 1 deformed and explicit steps at true scale, as the
owner's notes in #77 ask; a 0.24 mm deflection drawn as 10 mm no longer
reads as a failed part.

The distance and the target follow from the eight corners' exact
projections, for orthographic and perspective cameras and any direction of
view, so a long beam seen side on fills the width instead of a sphere
around it the height (#147). The free part is given as fractions of the
view, so overlays can be left out (#76); a margin is kept on each side.
Camera::fit is fit_in over the whole of a square view, and the headless
renderer fits to the picture's aspect.

Zoomed in on the hex20 crank arm, the element edges and the shaded faces
did not meet (#260). The mesh is conforming; the display drew each hex20
face and edge as straight chords between corners while the mid-side
nodes lie on the curved surface (up to 0.44 mm off the chord at 3 mm),
and drew the geometry's face boundaries from the design tessellation,
off both.
Now a quadratic face is cut into triangles whose vertices are its
corners and mid-side nodes, each edge is drawn as its two halves, and
over the mesh the geometry's edges (and a hovered design edge) are drawn
as the element edges on geometry edges (`DisplayEdge::feature`), so
faces, edges, feature lines and the highlight share their vertices.

Datum planes draw as a hatched square around the model, axes as a line through
it, each with its name, in the desktop viewport and the headless render. The
browser's Geometry node lists the datums and the partitions with the datum
each cuts by.

Geometry triangles remember their surface (body); the viewport and the
headless pictures draw each body of a multi-body design, such as the
cells of a partitioned part, in its own colour from the theme (eight in
turn), and a single body in the geometry colour as before.

`ui.view` and the MCP `screenshot` tool only turned to the named views, so
a picture sequence could only cut between them. `Orientation` (render) is a
camera orientation in degrees, {yaw, pitch, distance?}, checked as hostile
input: angles finite, distance finite and above 0, yaw wrapped, pitch
clamped to ±90, distance to 0.001–1e9. `modelcraft_engine::view::orientation`
parses it from JSON for both callers:
- control channel `ui.camera {yaw, pitch, distance?}` turns the app's camera;
- MCP `screenshot {camera}` turns it first (bridged through `ui.camera`,
headless in the CPU render, framed unless a distance is given). `view` and
`camera` are not given together.
