Translation4 returns a transform that displaces every point by v.

UnitVector3FromVector normalizes v, see [NewUnitVector3].

Add registers a body and returns it.

WithTab sets the ribbon tab the command appears on (its Category is the panel within that tab). Commands group two levels deep — tab → panel — so e.g.

WithTooltip sets the hover tooltip.

WithButtonStyle sets how the command renders in the ribbon (text/small-icon/ large-icon). Inventor's large buttons head a panel; small ones fill dense

WithIcon sets the command's icon asset key (resolved by the head to an SVG glyph). Pair it with WithButtonStyle to make the ribbon show the icon; a ke

Occurrences returns the components placed inside this composite definition.

AddPart creates a new part document in ws with a realized part component definition installed (not the bare doc-package placeholder), makes it active,

Emit delivers e to every Before-or-After handler for its type and returns the aggregate outcome. It uses a background context; see [EmitContext] for d

float parses the value as a real, trimming any padding. The error names the code and the offending text.

Destroy tears down ImGui, the Vulkan device, and the window.

Sub returns a−b componentwise.

NewExtrudeFeatures binds the collection to a feature engine.

String returns a stable name for diagnostics.

Contains reports whether sel is already in the set. Selectable handles are comparable value structs wrapping the underlying entity pointer/id, so iden

NewDressUpFeatures binds the collection to an engine.

Set creates the pane or replaces its whole tree.

WithEnable sets the enable predicate (nil ⇒ always enabled).

NewParameters returns an empty collection.

Sub returns q − o, with the same same-unit requirement as [Quantity.Add].

sketchSession returns a session in the sketch environment on the XY plane (the camera frames XY straight-on so a pixel maps to a sketch point).

typedPart adapts a handler that needs the active part and typed args: `r.mutating(wire.MethodWorkSurfacesRename, "Rename Work Surface", typedPart(rena

NewBuilder starts a body with a single shell. A solid body's shell is closed.

Normal returns the unit plane normal UAxis×VAxis.

AddByDistanceExtent adds an extrude of a single sketch region, growing distance (a closure, typically a parameter) under the given operation.

AddLine3D adds a straight 3D segment between two new endpoints.

Hypot returns √(a²+b²) — the Euclidean length used by distances and radii. Its gradient is (a·da+b·db)/hypot, zero at the origin (the non-differentiab

Sqrt returns √a (derivative 1/(2√a)); the gradient is zero at a==0 where √ is not differentiable, which keeps a degenerate (coincident) term from prod

AddByCenterRadius creates a circle from a new center point and a radius.

Text draws a line of unformatted text.

NormalAt returns the unit surface normal (du×dv normalized), or the zero vector at a degenerate point such as a sphere pole or cone apex.

ActiveDrawing returns the active document's drawing content with its title-block resolver wired to the workspace, or an error if the active document i

BeginFrame pumps window events, recreates the swapchain if needed, and starts a new Dear ImGui frame. Build the chrome after this, then call EndFrame.

Build returns the assembled body, with its shells regrouped to true face connectivity (M07-F06, #629) — a builder receives faces in arbitrary order, s

EndFrame renders the ImGui draw data into the swapchain (clearing to the given background color) and presents it.

Analytic solid primitives for the transient B-rep factory (M07-F05, Oblikovati/Oblikovati#628): block, cylinder/cone, sphere, torus. Sphere and torus

box builds a solid box [px,px+sx]×… by offsetting the cage vertices.

newPartWithBlock sets up a part whose active body is a side×side×2 block (built by an extrude), returning the session and the block body.

NewCamera returns a camera with a 45° vertical FOV looking down −Z by default; set Eye/Target to frame the model.

Plane returns the sketch's host plane.

Plane returns the current datum plane, also usable directly as a sketch host.

AddBase adds a non-parametric base feature wrapping imported bodies.

Geometry returns the imported mesh; Vertices/Edges/Faces expose its topology.

MarkDirty flags the document as having unsaved changes. Editing operations call this; saving clears it via [Document.ClearDirty]. The clean→dirty tran

Add creates a new document of kind t from the built-in template and registers it as the active document. The full template-file resolution via the pro

DimensionConstraints returns the sketch's dimensional-constraint collection.

Button draws a button and reports whether it was clicked this frame.

Contains reports whether p lies within the closed box.

Continue reports that the handler did not consume or block the event.

Vertices returns every distinct vertex in the body.

Error implements error.

AsUnit normalizes v, panicking only on the programmer error of a zero vector used as a fixed world seed; callers here pass constant non-zero axes.

Cells are classified into outer boundaries and holes by even–odd nesting; geometry that bounds no cell (a connected but unclosed chain) becomes an ope

register records one kind's codec, panicking on a duplicate or an incomplete pair — a programming error caught at construction, not a silent overwrite

Cross returns the cross product v×o.

newViewportWindow opens the head window, or skips the test if the environment has no display/Vulkan driver.

Annotations returns the sheet's annotations (CoG markers, revision clouds, parts lists, …).

NewUnitVector3 normalizes (x, y, z) into a UnitVector3. It returns an error when the input is too close to zero length to define a direction (the magn
