Tokyo Tier-1 Architectural Design Institute Migrates 450 CAD Seats to GstarCAD Architecture (Illustrative Scenario)
A prestigious Tokyo architectural institute handling high-rise commercial complexes and seismic retrofitting transitioned 450 drafting and structural documentation seats to GstarCAD Architecture 2027. By complying 100% with Japan's Ministry of Land, Infrastructure, Transport and Tourism (MLIT) CAD Standards and JIS A 0150, the institute maintained flawless public sector project approvals while liberating ¥397M in IT capital.
Illustrative scenario. This case study is a composite example built from typical enterprise CAD migration patterns. The organization, the people described and all figures are illustrative and do not describe a specific GstarCAD customer.

Executive Audit Summary
Scale: 450 Floating Network Licenses (GstarLM) | 5-Year Net TCO Preserved: ¥397,050,000 Saved over 5 Years (89% TCO Reduction) | Binary DWG Accuracy: 100.00% Zero-Loss | Retraining Downtime: 0 Business Hours
1. Industrial Challenge & Recurring License Rental Bottleneck
Headquartered in Chiyoda-ku, Tokyo, with design studios in Osaka and Fukuoka, the firm employs 620 licensed architects, structural calculation engineers, and building services draftsmen. The institute is renowned for complex urban transit hub redevelopments and seismic base-isolation retrofitting designs. Historically, design documentation relied heavily on AutoCAD and AutoCAD Architecture for detailed construction drawings (施工図) and municipal building permit filings (確認申請図面).
Autodesk’s transition from multi-user network licenses to Named User subscriptions severely disrupted the studio’s flexible workflow. Over 180 project-based external consultants, site inspectors, and university research fellows required intermittent CAD access. Maintaining individual annual subscriptions for non-daily users inflated software costs past ¥85 million annually. The institute's leadership enacted an immediate strategic mandate: adopt a high-precision, perpetual floating CAD platform that fully respects Japanese architectural drawing conventions.
2. 30-Day Technical Verification & Standard Compliance Protocol
The Tokyo Quality Assurance Division established a 30-day trial protocol to stress-test GstarCAD Architecture across active seismic isolation projects:
- MLIT Drawing Standard (国土交通省 CADデータ作成要領) Compliance: Rigorous automated testing proved that GstarCAD’s layer naming hierarchies, line weight mapping, and Japanese font rendering (MS Mincho / MS Gothic SHX vectorization) complied with municipal e-filing inspection engines without a single format error.
- Parametric Wall, Door, and Window Object Flexibility: Architects verified that GstarCAD Architecture's intelligent parametric architectural entities (2D/3D dual-state walls, custom Japanese sliding screens, and multi-bay structural grid systems) allowed rapid elevation/section generation without third-party add-ons.
- BIM Section Extraction Interoperability: Construction teams routinely import 2D DWG sections exported from ArchiCAD and Autodesk Revit. GstarCAD opened and resolved 250MB composite building section layouts with zero entity distortion or missing custom hatch patterns.
- SXF (p21 / sfc) Public Infrastructure Data Exchange: The engineering team validated seamless bi-directional conversion with Japan's mandated SXF open CAD standard for public works submissions, ensuring zero loss of semantic attribute layers.
3. Five-Year Total Cost of Ownership (TCO) Financial Audit
A rigorous five-year financial ledger comparison between Autodesk Named User subscription recurring rental and GstarCAD perpetual floating network licensing reveals massive capital savings:
| Investment Horizon | Autodesk® Subscription Model | GstarCAD® Perpetual Network | Net Capital Preserved |
|---|---|---|---|
| Year 1 (Deployment & Perpetual Network Servers) | ¥81,000,000 (450 Named User Seats) | ¥31,500,000 (450 Perpetual Floating Licenses) | ¥49,500,000 (61% Initial Savings) |
| Year 2 (Annual Maintenance vs Recurring Rent) | ¥85,050,000 (+5% Subscription Escalation) | ¥4,725,000 (Optional Version Maintenance) | ¥80,325,000 (94% Savings) |
| Year 3–5 Cumulative Expenditure | ¥281,400,000 | ¥14,175,000 | ¥267,225,000 |
| 5-Year Total Financial TCO | ¥447,450,000 | ¥50,400,000 | ¥397,050,000 Total Net Savings |
4. Production Rollout Blueprint & Long-Term Strategic Value
The institute deployed GstarCAD Architecture across all three offices using Active Directory GPO automation, pairing workstations with a centralized GstarLM network license pool. Floating token borrowing was enabled for site architects visiting building sites in Chiba and Yokohama.
Design teams achieved full project throughput within three business days. The institute channeled the saved ¥397M+ directly into sustainable timber construction R&D and proprietary real-time seismic simulation algorithms.
