Add BACTION/BACTIONTOOL workflows for compatible parameter endpoints, selected geometry and native action markers. Persist Move/Scale records, target handles and evaluation graph bindings; reuse shared adjacency editing with Lookup and the existing palette, tooltips and selection UI.
Evaluate endpoint changes in the disposable Test Block document from immutable starting geometry, with geometry/grip undo, source isolation and transformed-reference support. Preserve visibility representations and their native Basepoint anchor. Refuse unsupported options, value constraints and shared test references.
This milestone supports default Move and uniform Scale on basic drawing entities. Other actions, custom options, live preview and ordinary drawing-reference evaluation remain pending.
Validation: self-contained synthetic DWG/DXF roundtrips, graph adjacency, command cancellation/history, Test Block isolation/undo, transformed references, visibility/Basepoint and real-view palette/viewport input checks; broader block and dock suites.
Keep action object selection active across mouse picks/removals and advance only on Enter. Cover empty selection, multiple targets, Shift removal, marker placement and Move/Scale Test Block evaluation using viewport mouse events. Verified 10 focused, 320 block and 39 dock tests (6 existing opt-in block checks ignored).
Add native Basepoint placement and relocation, shared insertion and Test Block anchor behavior, and attribute-safe coordinate reframing. Wire native Lookup parameter placement and the Property Lookup Table editor through the existing palettes and BLOOKUPTABLE.
Stage input columns, rows, reverse lookup and audit across multiple tables; apply all drafts atomically as one undo entry. Persist native Lookup actions and graph dependencies while preserving unrelated objects and IDs. New inputs cover Linear and Polar distances; reference Lookup evaluation and geometry actions remain separate work.
Pin codec c418d92, kernel 0f6f225 and graph dcb9eda for correct R2010 inline constraint-group decoding. The codec regression uses a checked-in synthetic DWG and reproducible generator, with normal self-contained loading and edited DWG/DXF tests. Keep dock control tests independent of scene adapter warning dialogs in software snapshots.
Validation covers native round trips, all 17 research fixtures, graph preservation, insertion and attributes, staged editing, undo/cancel, and real palette/dialog controls.
Enable the existing palette rows and BPARAMETER choices. Rotation accepts a
center, picked or numeric radius, and picked or numeric default angle.
Alignment places a tangent direction from its base point. Flip places a
reflection line and state label, with native grip and state expressions.
Extend shared graph append/capacity checks for Flip's additional state node
while preserving existing subgraphs. Keep Polar/Rotation angle labels unique
in either placement order. Add editor graphics, extents and definition
reframing through the existing overlay/history/save paths.
This milestone implements native parameter placement and persistence.
Rotate/Flip action association, reference alignment/grip editing, parameter
property editing and parameter sets remain separate work.
Validation covers command and palette placement, cancellation, local/parent
undo, save/discard, native DWG/DXF objects, existing graph preservation and
the 17 research fixtures. Broader block/dock regressions and editor renders
are also checked.
Enable the three existing palette rows and BPARAMETER choices. Pick a base,
endpoint and label location to create the appropriate native parameter, one
end grip and its location expressions in the shared authoring graph.
Render editor dimensions and labels, preserve them when reframing the block,
and include them in editor extents. Reuse local undo/redo, save/discard and
native DWG/DXF persistence. Reject incomplete or invalid placement without
changing document data or history.
This milestone implements parameter placement. Action association/evaluation,
parameter property editing, alternate grip counts and parameter sets remain
separate work.
Validation: focused placement and palette interaction checks; Block Editor and
dock regressions; native append and DWG/DXF round trips in all 17 research
fixtures, preserving existing graph data and source files; app-view renders.
Enable Point in Authoring Palettes and BPARAMETER. Pick parameter and label
positions, then create the native Point, XY grip and position expressions in
one undo transaction. Draw editor-only markers and clear placement previews.
Share graph append construction with Visibility so both types coexist in
either order. Allocate node, expression and edge IDs independently; preserve
existing objects, nodes and relationships and reject malformed/opaque graphs.
Reframe parameter, label and grip with the edited definition. Include authoring
positions in editor framing while keeping reference geometry extents unchanged.
Retain save/discard and parent saved-edit undo. Action association/evaluation
and parameter property editing remain separate milestones.
Validation: 10 targeted, 286 block and 60 dock checks passed (overlapping
filters). Appending a Point to an existing native graph passed DWG/DXF
roundtrips in all 17 local fixtures; old objects and original checksums stayed
unchanged. Real-view palette interaction and rendered marker/label verified.
Add the current-state selector, Visibility States dialog and mode/show/hide
controls to the contextual ribbon, using shared icons, tooltips, modal UI
and adaptive flyouts. Disable the controls until a Visibility parameter exists.
Stage state creation, rename, deletion, current-state changes and reordering
until OK. Support copied, show-all and hide-all new states in one undo step,
preserve native graph metadata, and restore current-state identity on undo/redo.
Implement nonsaved BVMODE and display-only reveal during BVSHOW selection.
Cancelling selection leaves saved visibility flags and history unchanged.
Keep the existing command-line state workflows available.
Validation: 6 targeted tests; 277 block, 31 app dock, 35 ribbon and 12 history
checks passed (overlapping filters). All 17 local DWG fixtures passed in-memory
DWG/DXF preservation checks with unchanged original checksums.
Milestone 1: enable Parameters > Visibility and add interactive
BPARAMETER VISIBILITY placement using the existing native visibility
parameter, grip and state engine. Bare BPARAMETER currently offers only
Visibility; other parameter, action and set entries remain unavailable.
Show the placed parameter in the editor and support cancel, local undo/
redo, save/discard and saved-edit undo. Bind placement to its document
and definition, reject duplicates and invalid points, and protect existing
authoring graphs from replacement.
Keep visibility parameters and their grips aligned with geometry when a
BEDIT UCS change reframes the definition, including parameter-only blocks.
Validation: 9 targeted tests, 272 block checks and 58 dock checks passed
(overlapping groups). All 17 local DWG fixtures passed in-memory DWG/DXF
placement roundtrips and graph-preservation checks; originals unchanged.
In the Block Editor, BVSTATE makes a new visibility state, makes one
current, renames or deletes one; BVHIDE and BVSHOW hide or show the
picked objects in the current state (BVSHOW shows every object of the
block while they are picked). The first use makes the block dynamic.
The states are stored as the format keeps them: a
BLOCKVISIBILITYPARAMETER in the block's ACAD_ENHANCEDBLOCK evaluation
graph with its visibility grip and the grip's two location expressions,
the round-trip purge preventer, AcDbDynamicBlockTrueName /
AcDbDynamicBlockGUID / AcDbBlockRepETag on the definition and element
tags on each of its objects. The definition shows its first state; a
reference given another state gets its own evaluated *U copy, tagged
AcDbBlockRepBTag and linked back through AcDbBlockRepresentation /
AcDbRepData, so it shows that state and the other references do not
change. Saving the block drops erased objects from the states.
Checked: a block authored this way reads back with its states and
reference link from DWG and DXF, and the ODA converter accepts the DWG.
