Autodesk BIM 360 & ACC
ISO 19650 Cloud CDE & Data API Architecture

1. Platform Architecture & Enterprise BIM Management

Autodesk BIM 360 and the unified Autodesk Construction Cloud (ACC) represent the industry enterprise standard for cloud-based Building Information Modeling (BIM) management, multi-discipline Revit Cloud Worksharing (RCW), and ISO 19650 compliant Common Data Environments (CDE). Operating on Amazon Web Services (AWS) infrastructure and Autodesk Platform Services (APS / Forge API), the platform bridges structural engineering, architectural design, MEP coordination, main contractor site operations, and asset management.

In structural project delivery, BIM 360 / ACC serves as the single source of truth (SSOT) hosting live central models, managing automated model coordination clash spaces, executing formal document review workflows, and syncing 3D issue pins between office design models and site field devices.

2. ISO 19650-2 Compliant CDE Architecture & Metadata Matrix

A rigorous ISO 19650-2 Common Data Environment requires strict separation of information containers across four distinct lifecycle states:

3. Design Collaboration Swimlane & Package Workflows

The Design Collaboration module manages inter-disciplinary model exchanges without corrupting active Work-in-Progress (WIP) central files:

1. 1

   Revit Cloud Publish Set Setup

   Configuring Revit Publish Settings to select 3D analytical views, sheet sets, and shared parameters exported to ACC Docs upon cloud sync.

2. 2

   Package Assembly & Metadata Tagging

   Assembling a weekly Structural Design Package on the BIM 360 timeline swimlane, attaching revision notes, ISO 19650 suitability codes (e.g. S2 - Suitable for Information), and BCF issue links.

3. 3

   Visual 3D Delta Comparison

   Utilizing the web viewer visual difference engine (color-coded Added green, Removed red, Modified yellow) to inspect architectural wall movements before consuming the package.

4. 4

   Consuming & Linking

   Consuming the published package updates the external link copy inside the structural team's Consumed/Architecture/ folder, ensuring controlled background updates.

4. Autodesk Platform Services (APS / Forge) Python API Automation

Autodesk Platform Services provides REST APIs for programmatic CDE management. Below is an executable Python script using `requests` to perform 2-Legged OAuth2 authentication, retrieve project hub containers, and trigger SVF2 model translation for web viewing:

# Python Script: APS / Forge Data Management API Integration
import requests
import json
import base64

CLIENT_ID = "YOUR_APS_CLIENT_ID"
CLIENT_SECRET = "YOUR_APS_CLIENT_SECRET"

# Step 1: OAuth2 2-Legged Authentication Token
auth_url = "https://developer.api.autodesk.com/authentication/v2/token"
headers = {"Content-Type": "application/x-www-form-urlencoded"}
payload = {
    "client_id": CLIENT_ID,
    "client_secret": CLIENT_SECRET,
    "grant_type": "client_credentials",
    "scope": "data:read data:write bucket:read"
}

auth_res = requests.post(auth_url, headers=headers, data=payload)
access_token = auth_res.json()["access_token"]
print(f"APS OAuth Access Token Acquired: {access_token[:15]}...")

# Step 2: Trigger Model Derivative SVF2 Translation Job
urn = "urn:adsk.objects:os.object:bim360_project_bucket/Structural_Model.rvt"
encoded_urn = base64.b64encode(urn.encode('utf-8')).decode('utf-8').rstrip('=')

deriv_url = "https://developer.api.autodesk.com/modelderivative/v2/designdata/job"
deriv_headers = {
    "Authorization": f"Bearer {access_token}",
    "Content-Type": "application/json"
}
job_payload = {
    "input": { "urn": encoded_urn },
    "output": {
        "destination": { "region": "us" },
        "formats": [{ "type": "svf2", "views": ["2d", "3d"] }]
    }
}

job_res = requests.post(deriv_url, headers=deriv_headers, json=job_payload)
print(f"Model Derivative Job Status: {job_res.status_code} - {job_res.json().get('result')}")
