Add the typed document facade and plugin IPC adapter. Prepare bulk edits before mutation, preserve undo and dirty state, keep profile elevations, validate numeric inputs and session bindings, and generate Python constructors with typed results. Reuse existing entity transforms and profile conversion. Compute mass properties and closed-surface bounds in cadkernel; pin its main revision 6a5e6fc2822f6af6b2611cd605b44437b35158f0. Keep plugin API metadata at version 6. Validation: 646 native application tests, 597 kernel tests, 12 document API tests, 91 plugin API tests, 3 Python tests, default/IPC feature builds and wasm32 check passed.
ocs_doc_api
Typed document operations and queries for OpenCADStudio plugins and hosts. The same facade runs over an in-process backend or the plugin IPC channel.
use ocs_doc_api::{ApiResult, DocApi};
fn intersect_solids(api: &DocApi) -> ApiResult<f64> {
let doc = api.document(api.active_tab());
let a = doc.solids().create_cuboid([0.0; 3], [10.0; 3])?;
let b = doc.solids().create_cuboid([5.0; 3], [10.0; 3])?;
a.intersect(&b)?.volume()
}
Each successful write marks the document changed and records one undo step.
A failed operation leaves the document unchanged. Bulk creation and transforms
prepare every entity before applying changes. Separate calls commit separately;
OpGroup offers best-effort cleanup of creations, not rollback.
Boolean intersect, union and subtract replace the first solid and erase the
second. intersects only tests bounding-box overlap. Volume and centroid are
computed by the kernel from a tessellated solid (chord tolerance 0.1 drawing units,
angular tolerance 0.0001 radians), then cached per geometry revision. A request
may compute at most 32 uncached mass properties; excess work returns an error.
Bulk operations and query batches are capped at 100,000 items.
Transports bind to one document tab. Typed handles from another transport and
requests for another tab are rejected. Raw ObjectId values are relative to the
receiving document. Errors are serialized as ApiError variants over IPC.
