Creo Integration (PTC Creo Parametric)

_CreoBridge implements all five strategy profiles from the Creo brainstorm inside _AugmentedIntelligence, with a full offline mock session so CI and desktops without Creo still work.

Strategy profiles

Profile	Strategy	Default use
live	Interactive session bridge (VB API / J-Link worker)	Co-pilot while user works in Creo
batch	Headless job runner	Overnight configure/export packs
configurator	Parameter / family-table only	Safest agent default
file	File-centric STEP/PDF/JSON (no live session)	Locked-down sites / neutral files
toolkit	Toolkit/OTK advanced façade	Licensed deep feature access

Commands

Plugin façade:

Bridge manager:

[text]
bridge start creo
bridge stop creo
bridge info creo
bridge replay creo tests/fixtures/creo/context.json
bridge dry-run creo on

Quick start (offline mock)

[text]
creo doctor
creo bridge start
creo demo
creo param set LENGTH 120
creo regen
creo mass
creo export step creo/work/out.step
creo recipe run config_to_order LENGTH=150 THICKNESS=8
creo selftest

Exports honor dry_run (default on): files are written as *.dryrun markers describing the would-be artifact. Turn off for real sandbox writes:

[text]
creo dry-run off
creo export step creo/work/out.step

Environment

Variable	Meaning
AI_CREO_PROFILE	Initial profile (configurator, live, …)
AI_CREO_API	mock (default) \	vb \	jlink \	trail \	toolkit
AI_CREO_HOST / AI_CREO_BRIDGE_PORT	Worker TCP (default 127.0.0.1:8777)
AI_CREO_TOKEN	Shared bridge token
AI_CREO_WORKDIR	Sandbox directory (default creo/work)
AI_CREO_WORKER	Path to worker script/exe
AI_CREO_EXE	Path to parametric.exe / Creo install
AI_CREO_DRY_RUN	on/off default dry-run

Worker sidecar

Mock worker (protocol stub):

[text]
python tools/creo_worker/creo_worker.py –port 8777 –token change-me

Replace execute_verb with VB API / J-Link for production. The host keeps tokens and ethics gates; the worker should not call cloud LLMs.

Recipes

Built-in recipe names (also under creo/recipes/*.yaml as documentation):

config_to_order — param batch → regen → STEP
family_instance — activate family table row
drawing_refresh — regen + PDF
supplier_pack — STEP + PDF + BOM CSV
what_if_mass — LENGTH sweep mass table
interference_gate — block export on mock collision
start_part_apply — new from template params
design_review_brief — context JSON for LLM
print_prep_stl — STL export

Safety

Default profile: configurator (no freeform feature creation).
Default dry-run on for exports when using live-oriented flows.
Parameter limits enforced on demo model (LENGTH 20–500 mm, etc.).
Failed features simulated when HOLE_DIA is unsafe vs plate size.
Toolkit profile can create unknown parameters; others reject unknown names.

Fixtures

[text]
tests/fixtures/creo/context.json
tests/fixtures/creo/action_param_set.json
tests/fixtures/creo/job_batch.json

Files

Path	Role
CreoBridge.hpp / .cpp	Host bridge + all profiles
tools/creo_worker/creo_worker.py	Mock sidecar
creo/recipes/*.yaml	Recipe docs
BuiltinPlugins.cpp (creokit)	Plugin SDK entry
BridgeManager id creo	Unified registry

Live Creo (next hardware step)

Install Creo Parametric + enable VB API or J-Link.
Implement real verbs in creo_worker (or C# worker).
Set AI_CREO_API=vb (or jlink), AI_CREO_WORKER, AI_CREO_EXE.
creo profile live → creo bridge start → creo context.

Until then, mock models (BRACKET_A.PRT, BRACKET_ASM.ASM) exercise the full command surface.
