A DIMENSION references the block "that contains the entities that make up
the dimension picture", and that block is the picture: AutoCAD requires
it and draws it, BricsCAD draws it when present and only renders from the
dimension variables when it is missing. OCS re-derived the picture from
DIMVARS every time and ignored the block entirely.
That works while a style agrees with what the drawing actually drew. A
Revit-exported schedule here does not: its style stores DIMTXT already in
drawing units beside a DIMSCALE meant to scale it, so the text came out
three hundred times too tall, and each dimension carries a DIMFXL
override that is likewise already in drawing units, so the extension
lines ran nearly a million units past the points they measure.
Neither is guesswork about units now. The block holds the geometry the
drawing was authored with, so it is drawn: the contents are already in
world space and the block's base point is the origin, and the identity
instance that carries them exists only to reuse the scene graph's
ByBlock / layer-0 colour resolution. Every wire answers to the dimension,
so a pick still selects the dimension rather than one of its pieces.
Re-deriving stays as the fallback for a dimension with no block.
Annotative dimensions keep the old path: their several representations
are separate blocks and choosing between them is what the annotation
machinery already does, while the doctrine above assumes one picture.
A picture is only good while its inputs hold, so it is dropped when they
change: editing a dimension's properties, and saving the dimension style
it is drawn with. Entity edits already dropped it.

The status-bar units button wrote INSUNITS, which nothing on screen reads.
INSUNITS only tells the drawing how to scale content arriving from
elsewhere, so picking a unit relabelled the drawing and changed nothing
visible — the selector looked broken because the variable it moved was
invisible.
Point the button at LUNITS instead, the setting that decides how every
coordinate and distance is written, and give the three questions the word
"units" runs together a place each:
- The button offers the five length formats, each shown beside a sample of
itself, so Engineering and Architectural are told apart by sight.
- UNITS / DDUNITS opens a real dialog: length and angle format and
precision, the direction angle zero points, whether positive angles run
clockwise, and the insertion unit. Its sample comes from the same
formatters the drawing uses, so it cannot drift from the readout.
- DWGUNITS converts. Model geometry, viewport framing, the header's length
defaults and each dimension style's scale all move together in one undo
step; paper space is left alone, since the sheet is still the same sheet.
Locked layers are converted too — a half-converted drawing would be at
two scales at once.
The coordinate readout formatted at four decimal places whatever the
drawing asked for; it now goes through the same format_length the
properties panel uses. That made the angle formats reachable in turn, so
degrees-minutes-seconds now carries the d/'/" marks that say which
convention it is, and surveyor's units are written at all.
Typed input is still plain decimal: a length the readout writes as
5'-6 1/2" cannot yet be typed back. ANGBASE and ANGDIR are stored but not
yet applied to displayed directions.

Registering as the .dwg/.dxf handler was reachable only by typing
FILEASSOC, which is also the only thing that installs the icons the
desktop shows — so a user with no reason to know the command had no way
to arrive at either.
The checkbox makes the same two calls the command does, so the stored
setting and the actual registration cannot drift apart. A registration
the system refuses puts the checkbox back rather than leaving it showing
a state that is not true.
The line under it says the icons come with it, since that is what sends
people looking for this in the first place.

Drawings arrive from elsewhere carrying someone else's layer names, and
folding them into a set of house layers meant renaming and merging by
hand, one layer at a time.
LAYTRANS reads a layer set out of another drawing and moves this one onto
it. Given a file it maps every name the two already share and translates
at once, which is all most incoming drawings need. Bare, it opens a
translator: the drawing's layers on one side, the loaded set on the
other, mappings built up between them and applied only on Translate, so a
mapping can be reconsidered and the whole translation is a single undo
step. Mappings can be saved and read back, objects can be forced to
ByLayer so the target layer's properties are what actually shows, and the
result can be written out as a log.
The move itself is the one LAYMRG already made for a single pair, so
LAYMRG now goes through it too rather than keeping its own copy.
Three things fell out for free or nearly so. A standards file is a
drawing, so .dws and .dwt need nothing but a place in the file filter.
The entity list is flat and holds block definitions, so objects inside
blocks travel with everything else instead of being stranded on a layer
that no longer exists. And a target layer that this drawing already has
is left alone: the drawing has an opinion about it, and restyling it
would reach past what was asked for -- only newly created targets take
the standard's properties.
Mappings are saved beside the drawing rather than inside a DWS. That is
where AutoCAD keeps them, but putting them there would mean inventing a
place in the drawing that nothing else reads back.

Removing the binary wireframe event left add-ons with no way to set a
visual style except by spelling out a command string. Give them the
intent back, in the vocabulary everything else now speaks.
The name is carried as text rather than the render-mode type: this crate
is dependency-free by default and only pulls acadrust in behind the host
feature, which is not a weight to add to the manifest contract for one
enum. The host resolves it against the same list its ribbon, its picker
and its commands read, so an add-on can offer exactly the styles the
application does and no others. An unknown name says so and lists the
ones that exist, from that same list.

The ribbon offered four styles and dispatched each one's id as a command.
Two of those ids were not visual-style commands: "Shaded" carried SOLID,
which draws a 2D filled polygon, so choosing it started a draw command;
"Hidden" carried HIDDEN, which matched nothing at all, so it did nothing.
The intent had been for the button to fire its tool's event, but the
dropdown never reads one -- it dispatches the id.
Behind that sat two generations of the same feature. The render-mode
picker offered the seven styles a viewport can actually be drawn in;
everything else -- the ribbon, VSCURRENT, SHADEMODE, VISUALSTYLES and a
handful of bare verbs -- went through a binary wireframe-or-shaded flag
that could only approximate them, reporting "Hidden (shown shaded)" and
"X-Ray (shown as wireframe)" when asked for something it had no way to
draw. Four descriptions of one choice, each drifting on its own.
There is one list now. Each style names itself once -- mode, label, icon,
and the command that applies it -- and the ribbon, the picker, the
VISUALSTYLES verb and the interactive prompt all read from it, down to
the line that lists the choices, so what is offered cannot disagree with
what works. Keywords are the render modes' own names, since there is one
set of styles left to name.
The binary path is gone rather than kept alongside: its message, its
module event, the tool definitions that produced it, the ribbon's
special-cased highlight arms, the bare style verbs and the older keyword
spellings. X-Ray goes with it -- no render mode draws one, and it was
already coming out as a plain wireframe. Three files that had been left
holding a single icon constant each fold into the list.
Note: ModuleEvent::SetWireframe leaves the plugin API with it.

Only Previous and Last were on offer, so Window, Crossing, Fence, the two
polygons and All could not be reached at all -- and with no keyboard to
type them into, the buttons were the only way in.
Window and Crossing fix the sense of the next box. Dragging derives that
from the direction the corner travels and would overwrite it the moment
the corner moved, so the derivation stands down while a keyword holds it.
Add and Remove decide what a pick does for the rest of the round: Remove
subtracts the way Shift already does, rather than through PICKADD, which
decides whether a pick *replaces* the set and so would have wiped
everything gathered so far. Both are dropped when the next command
starts, since neither outlives the selection that asked for them.
Fence and the polygons are picked point by point, which TRIM and EXTEND
already ask for. That gesture -- the points, the rubber-banded dashed
preview, whether the path closes -- moves into one place both bind to,
and the two preview builders duplicated in trim.rs go with it.
A fence is not the polygon test with crossing set: that closes the point
list and counts whatever lies inside, so a line drawn past a row of
objects would take everything behind it too. It gets a hit test that only
counts a real intersection, and skips the area-based geometry entirely.
The lasso gathered its hits from wires, hatches, block hatches, meshes and
block meshes inline; the new modes need the same list, and a second copy
would drift. Both now come through `Scene::path_hit_handles`.

Extension answered "which acquired ray is this snap on?" twice, from two
different tests: the overlay picked its guide by off-ray distance in
screen pixels, while typed-distance entry re-searched the tracking set in
world space. Two tests can disagree, and the ways they disagree are both
bad -- a guide on screen that typing ignores, or a distance running off
along a ray the user cannot see. The second search could also come up
empty on its own, since only four acquisitions are kept and the oldest is
dropped as new ones arrive.
Ask once. The search that draws the guide now also reports the endpoint it
drew from, the snap carries it, and typed distance reads the ray straight
off that -- the direction is just the way from the endpoint to the snap,
which sits beyond it by construction. The screen-space test stays the only
one, which is what the guide wanted anyway: it stays scale-independent
where a world test would not.
Also correct the tracking-point doc: it claims XZ with Y=0, but
`edge_dirs_at` builds every direction from X/Y with Z zeroed and the rays
follow it.

The extension anchors needed the same pane-to-canvas lift the snap
marker already got, but the block that added it was placed next to the
one that was already there rather than merged into it, so `screen` took
the tile origin twice. A single full-canvas tile has no origin to add, so
it only shows once the viewport is split. Fold the anchors into the
existing block.
Also require the ray to pass through the snapped point before offering it
as a distance reference. Only four acquisitions are kept and the oldest is
dropped as new ones arrive, so the ray that produced a snap can be gone by
the time a distance is typed; picking the nearest survivor unconditionally
sent the point off along an unrelated ray instead of falling back to plain
point input. `extension_snap` projects onto the ray in exact f64, so the
tolerance only has to clear rounding, scaled with the coordinate to hold at
UTM magnitudes.
