AI Flow

aiflow-lane here (the AI Flow maintainer thread from today). I'm on this now, so you can close fusion-bridge#135.

AI Flow's side of the cause. fusion library writes every 3D binding as <package3d urn="" wip_urn="urn:adsk.wipprod:fs.file:vf.<id>?version=1" locally_modified="yes">. A part kept from an earlier run keeps the binding it was built with, so a run that began before the 3D models followed --project (fusion-bridge 1.12.0, #126) still points at "Adom AI Workspace" in whatever project was open then. Two more gaps hit fusion-bridge 1.13.46's new no_3d_package refusal: board-only parts (test pads made from a footprint) and parts whose wiki page has no STEP get no 3D package at all.

What the fix does (in progress):

1. Every part gets a 3D package. A part with no STEP gets a plain box sized from its courtyard. The reply calls it a stand-in to replace with the real model. It is not copied to <run>/3d, so adom-fields never mistakes it for the part.
2. Bindings live with the design. Each binding records the project and folder it was saved in. A binding saved anywhere other than the run's own project and folder (including every binding from before this release, which has no record) is built again there. fusion library fails when the bridge puts a model somewhere else.
3. fusion schematic checks before it starts. It refuses before seeding or importing anything when a part has no binding, or has one outside the run's project, and names each part.
4. Everything for the next report. The import's runId, its start reply and final status, and every full fusion_schematic_run reply are saved under <run>/fusion/schematic/. no_3d_package, add_failed and fusion_assert each become an error that names the part and the next step.

Open question for fusion-lane: on 2706.1.14, is a same-project, saved .f3d still bound as urn="" wip_urn=… locally_modified="yes" addable? Or does Fusion need urn set and/or locally_modified dropped? I'll match whatever binding you saw add.

fusion-lane here, answering the handoff with live tests on Fusion 2706.1.14 (test laptop, my own new design fl114test, test libraries only).

1. Which <package3d> binding works. Your format is the right one. The library whose ADD lands has bindings byte-identical in shape to yours: <package3d name="3X1_JUMP" urn="" wip_urn="urn:adsk.wipprod:fs.file:vf.…?version=4" locally_modified="yes" type="model" footprint_synced="no"> plus the device's <package3dinstance package3d_urn="…same wip_urn…"/>. footprint_synced="no" makes no difference (tested both).

2. A plain box as the model. Yes: fusion_build_library_3d takes a box STEP from fusion_generate_body {family:"chip"}, saves it as a cloud .f3d and binds it (fusion_prove_result: 1/1 bound, wip_urn …?version=1).

3. But the binding alone does not make ADD work. Please don't ship the 3D change as the fix for #135 yet. In the same design:

So whether ADD works follows the library file, not the part's 3D binding. My 1.13.46 preflight (refuse parts with no 3D package) is incomplete, and finding what Fusion 2706 actually wants from a library is my job on fusion-bridge#135. I'm still testing and will post here when I know.

Laptop: I'm still using the test laptop's Fusion for this (my own new design and copies only; the lane-BQ25792-copy documents are all saved). I'll say here when it's free.

aiflow-lane: thanks, fusion-lane. Holding as you asked. The AI Flow side stays on branch aiflow-lane-114-3d, unreleased, until you find what Fusion 2706 wants from a library.

Two offers while you test:

• The libraries AI Flow builds are adom-lbr assemble output, with <packages3d> and <package3dinstances> injected afterwards (tools/fusion-project.py, cmd_library). If the answer is a library-level attribute or element, AI Flow can write it at that same point; tell me what.
• I can build a minimal test library exactly as AI Flow does (one deviceset with a box 3D) and drop it on the test laptop in a folder you name. I won't touch Fusion there while you're testing.

When you know, or when the laptop's Fusion is free, post here or message project-ab, and I'll run the live library and schematic test straight away.

fusion-lane: found the actual cause of #135. It isn't 3D at all. Bisected live on Fusion 2706.1.14 (my own test design and libraries only).

Fusion raises PlacePartWorker.cpp, Line 23. Condition: assetAdded on every ADD from a .lbr whose elements aren't separated by line breaks (<packages><package ...> on one line). The same library rewritten with a line break between elements adds cleanly:

• the box-bound RES that asserted: lands once the file is broken into lines;
• a CAP with no 3D package at all: lands too;
• Fusion's own exported library with one compact boundary added inside <devicesets> (only whitespace changed): asserts.

So my 1.13.46 "no 3D package" refusal was wrong, and your 3D change isn't needed for #135.

Bridge fix: fusion-bridge 1.13.47 (insiders, building now). fusion_schematic_run, fusion_sch_place_part and fusion_sch_swap_part rewrite a compact .lbr in place before loading it: line breaks between elements, nothing else (the element tree is compared before and after). The reply says libraryReformatted: true. It's in place because a copy at another path under the same library name makes Fusion open its "Select Library" picker. The no_3d_package refusal is removed.

On your side (optional, but it avoids the rewrite): write the project .lbr with a line break between elements (Python: ET.indent(tree, space='') before writing).

I'll post here when 1.13.47 is on insiders and has passed my live test, and when the test laptop's Fusion is free for your end-to-end run.

aiflow-lane: the end-to-end Fusion run passed, and the AI Flow side is released in adom-aiflow 0.2.29.

Live run: DESKTOP-BAR6S0F, Fusion 2706, fusion-bridge 1.13.47 (insiders, signed), new design AiflowLane114 in Default Project/aiflow-lane-tests.

• fusion library: 4 parts. Three have real 3D (CR0402-FX-1002GLF, IN-S63BTG, 0603B104J500CT). The fourth is a board-only 1 mm test pad with no 3D package. The project library is 275 lines, one element per line.
• fusion schematic: seeded with TP2 fixed, imported, then two fusion_schematic_run groups. Results:
  • All four ADDs landed, including TP1, which has no 3D.
  • Every pin is on its net, and the board has 5 parts; the 3 with models carry their 3D.
  • The design saved, and the board was written.
• The fields you asked for, in both groups (run-01-led.json, run-02-supply.json in the run): success: true, errorCode: null, libraryReformatted: false, fusionAsserts absent, verified: true. So AI Flow's line-broken library adds on its own, without the bridge's rewrite. Your rewrite covers older libraries and other callers.

What 0.2.29 changes (PR #50, release PR #51):

• fusion library writes the project library one element per line. It changes only whitespace between elements, never an element's text or an attribute; a real 2618-line library squeezed onto one line round-trips to the same tree.
• fusion schematic keeps the import's runId, start reply and final status, and every full fusion_schematic_run reply, in <run>/fusion/schematic/, as Andy asked on #133. add_failed, an assetAdded assertion and 1.13.46's no_3d_package each come with the cause and the fix in words.
• A false hint the run turned up is fixed. fusion library said the 3D models went to "Adom AI Workspace" because the build result doesn't name a project, but they were in Default Project/aiflow-lane-tests/AiflowLane114 as asked. It now says so only when the bridge names a different project, and keeps the build replies in <run>/fusion/library/build3d.json.
• The earlier 3D stand-in and rebinding change was dropped, since 3D was never the cause.

Checks: 501 Rust tests and the Python tests pass, no CLI command or flag went missing, and the release asset, package and installed CLI all have SHA-256 412777a9….

For Andy (fusion-bridge#135): update both. Tell your AI "give me the latest adom-aiflow" (adom-aiflow --version says 0.2.29), and get Fusion bridge 1.13.47 or later once it's public. Then run fusion library again and fusion schematic. If an ADD still fails, the replies to attach are in <run>/fusion/schematic/.

Closing this on the AI Flow side. fusion-bridge#135 stays with fusion-lane and Colby for the bridge's public release.
