Preserve linked sketch identities through deterministic face projection and resizing. Fix origin-corner picking, persistent inline navigation, appearance editing, configuration styles, component properties, contact sweeps, sheet exports, analytic STEP offsets, and bounded rolling-ball fit accuracy. Validated with full cargo xtask ci, native workflow screenshots, repeated enclosure replays, and analytic geometry regressions.

# Assembly physical properties
|
|
|
|
The Browser's component **Properties** action measures the selected assembly placement,
|
|
including its nested components. Select the root design to measure every instance in the
|
|
assembly. The window shows material-aware mass, volume, surface area, center of mass and
|
|
the world bounding box. Pending occurrence moves are included without capturing them.
|
|
|
|
The same measurements are available through commands:
|
|
|
|
```json
|
|
{"command":"component.properties","params":{"component":"Bracket"}}
|
|
{"command":"component.properties","params":{"component":"root"}}
|
|
{"command":"component.properties","params":{"component":"Subassembly","descendants":false}}
|
|
{"command":"occurrence.properties","params":{"occurrence":"Bracket:2"}}
|
|
```
|
|
|
|
`component.properties` defaults to the active component and measures its first placement.
|
|
`occurrence.properties` measures the chosen instance. A nested occurrence can appear beneath
|
|
several instances of its parent; supply `path` (the complete list of occurrence ids from the
|
|
root) to choose one of those placements. An ambiguous occurrence without a path returns an
|
|
error. Both commands accept `descendants: false` to measure only directly owned bodies.
|
|
|
|
Results contain a `bodies` list and a `total` object. Each body's entry identifies the original
|
|
body name, owning component and occurrence path. Physical material density is resolved from
|
|
that original body, so copies keep their material and mass. Values use millimetres, square
|
|
millimetres, cubic millimetres and grams; coordinates use the world frame.
|
|
|
|
Mass and center of mass account for each body's density. Volume and area are summed over
|
|
placed bodies, including overlapping bodies and repeated instances. Measurements use the
|
|
kernel's tessellation-based body measurement. An empty component reports zero totals and
|
|
null center of mass and bounding box. A failed body measurement returns an error instead of
|
|
presenting an incomplete assembly total. These commands leave geometry, pending placements
|
|
and undo history unchanged.
