Project Health

Schedule	Scope	Budget	Quality	Resources	Phase	Complete	Target
🟢 Ahead	🟢 Baselined	🟢 Under Budget	🟢 Validated	🟡 Solo Dev	P1c✅/P2	80%	Dec 31

Schedule Impact: ~2 months ahead of schedule. P1 (Analysis) ✅ complete. P1c (Integration & Bug Fixing) ✅ complete — 17 bugs found and fixed, all tracked via GitHub Issues. P2 (Design) ▶️ active — alpha testing running, several GUI improvements already shipped. Installation validated across ALL operating systems (XP through Win10 x64) with AutoCAD 2000; Win10 x64 is compatible with Win11 x64 — no additional work needed. WiX installer development permanently sidelined — Autodesk App Store accepts compiled VLX uploads directly with a wizard-based submission process, eliminating the need for a standalone MSI installer. Total Uninstall continues to handle VM deployment. NanoCAD integration attempted but failed (incompatible extension mechanism). AutoCAD 2000 running on Win10 x64 via WoW64 registry fix — an unsupported path by Autodesk, but fully functional.

2026 Roadmap

Legend: 🟢 Complete | 🔵 In Progress | 🔴 Behind | ⬜ Planned | Today: Feb 25 ↓ | Variance: ~2 Months Ahead

💰 Budget Impact Update (Feb 25)

Key Discovery: Autodesk App Store accepts compiled VLX uploads directly with a wizard-based submission process. This permanently sidelines the WiX installer effort — no standalone MSI needed.

Code Signing is still required for App Store submission:

• Installer Tool: WiX = NOT NEEDED — Autodesk App Store handles distribution

• Code Signing: OV = $200/yr | EV = $400/yr (required for App Store)

Total 2026 Distribution Cost: $200/year (OV signing only — no installer tool needed)

• ✅ 9 monitoring data files captured via Total Uninstall, Inctrl5, Regshot across all 3 VMs

Key Discoveries (Week 5: Feb 13):

• ✅ Win10 32-bit: FULL STACK WORKING — AutoCAD 2000 + CV + COM automation

• ✅ Auto-config script created — Configure-ConstructiVision.ps1 handles HKCU registry setup

• ✅ P1 InstallShield Sprint ABORTED — Low ROI on .rul recompilation; proceed directly to WiX

• ✅ Total Uninstall restore validated as deployment method for both install and payload source

Key Discoveries (Week 6: Feb 16-17):

• ✅ v3.60 source recovery COMPLETE — 12 missing .lsp modules recovered from v3.60 archive

• ✅ 3 crash paths FIXED — wd_dlg (Standard Opening), wc_dlg (Weld Connections), wall_dlg (Wall Line)

• ✅ TB11-01x32 deployed — 134 → 195 files, nightly auto-pull on 4 VMs (108, 109, 201, 202)

• ✅ Win10 64-bit: FULL STACK WORKING — Wow6432Node COM fix (103 CLSIDs, 104 Interfaces, 6 ProgIDs)

• ✅ Both x32 and x64 crash-free — program runs and loads drawings on both architectures

• ✅ Architecture docs published — Doc 28 (TB11-01x32) and Doc 29 (TB11-01x64) with full registry footprint

• 📌 Alpha testing ACTIVE — GSCI engineers (Terry, Tai) on VM 201; Dat on VM 202

Key Discoveries (Weeks 7-8: Feb 18-25):

• ✅ 17 bugs found and fixed — complete bug fixing sprint during alpha testing (see 32-tb11-bug-tracker)

• ✅ 2 critical serialization bugs — savelay.lsp ENAME/XData filtering + layout.lsp index bug (Bugs 16-17)

• ✅ 3 latent PB11 bugs discovered — existed in original production build but never triggered until new workflows

• ✅ TB11-01x64 fully synced — x64 fork updated with all x32 patches including missing inspanel.lsp

• ✅ Autodesk App Store accepts VLX directly — wizard-based submission eliminates need for WiX/MSI installer entirely

• ✅ Win10 x64 compatible with Win11 x64 — no additional work required for Windows 11 support

• ✅ P2 Design already active — drawing type dialog, file browser fix, vla-open workflow, dirchk fix shipped

• ✅ #| |# block comments NOT supported — AutoCAD 2000 (load) can’t parse them; reverted to ;;

• 📌 XData refactor plan created — systematic approach to ENAME/XData filtering across all serialization modules

P1b: Installer Development — ❌ PERMANENTLY SIDELINED

Date	Milestone	Deliverable	Status
Feb 13	Win10 32-bit validated	Full stack working with auto-config script	✅ Done
Feb 13	Total Uninstall payload validated	152 files, 5.5 MB as WiX source	✅ Done
Feb 16	v3.60 source recovery complete	12 modules recovered, TB11-01x32 deployed	✅ Done
Feb 17	Win10 64-bit COM fix complete	Wow6432Node registry fix, both arches crash-free	✅ Done
TBD	WiX installer development	Deferred to end of P3 (Security)	❌ Not Needed

Impact: Autodesk App Store accepts compiled VLX uploads directly with a wizard-based submission process. This permanently eliminates the need for a standalone WiX/MSI installer — saving significant development time and the Pluralsight WiX training budget ($29). Total Uninstall continues to handle VM deployment during development. Distribution will use Autodesk’s built-in App Store packaging instead.

Feb 10	8 installer bugs cataloged with severities	🏆 Complete root cause analysis (profile detection = #1 bug)

🔍 Weeks 7-8 Key Learnings (Feb 18-25)

Critical Success: P1c Integration COMPLETE — 17 bugs fixed. Bug fixing sprint discovered and resolved 17 bugs including 2 critical serialization errors, 3 latent PB11 bugs, and multiple crash-path fixes. All tracked via GitHub Issues with automated sync. P2 (Design) is now active with several improvements already shipped.

• 17 Bugs Fixed: Complete bug fixing sprint — VLX detection, nil guards, ssget, walline recovery, inspanel fast path, ENAME/XData serialization, tiltup/layout index bugs. See 32-tb11-bug-tracker

• GitHub Issues Infrastructure: 17 issues created with 18 custom labels (severity, autolisp, serialization, version, build, arch, phase). Automated sync workflow pushes bug tracker updates to GitHub Issues.

• WiX Permanently Sidelined: Autodesk App Store accepts compiled VLX uploads directly with a wizard-based submission process. No standalone MSI installer needed — saves significant time and budget.

• Win11 Compatibility Confirmed: Win10 x64 is compatible with Win11 x64 — no additional work required for Windows 11 support.

• TB11-01x64 Fully Synced: x64 fork updated with all x32 patches including missing inspanel.lsp.

• P2 Design Already Active: Drawing type dialog, file browser fix, vla-open workflow, dirchk fix, and formatting refactors all shipped during alpha testing.

• Next Steps: Continue P2 GUI improvements based on alpha feedback → input/output validation → code refactoring

🔍 Week 6 Key Learnings (Feb 16-18)

Critical Success: Project is ~2 months ahead of schedule. P1c (Integration & Bug Fixing) and P2 (GUI Review) were scheduled for April-May but both phases are active or imminent in February. All 5 OS platforms validated. All crash paths fixed. Alpha testing running.

• Path Analysis Complete: Every menu click (40 paths + 20 panel property toggles) tested end-to-end — revealed 3 crash bugs (all fixed) and fully documented legacy architecture (menu → LSP → DCL mapping)

• NanoCAD is a Dead End: NanoCAD doesn’t support menugroup, VLX/ARX loading, or COM automation. Only basic LSP works. Not viable as an alternative CAD platform for ConstructiVision.

• WoW64 Integration is a Win: AutoCAD 2000 on Win10 x64 works by copying registry keys to Wow6432Node. Autodesk does NOT support this path, but it’s fully functional. This was a novel approach — no documentation exists for it.

• Installer Not Needed Yet: Total Uninstall fully handles install/remove across VMs. WiX installer deferred to end of security phase — focus now shifts to product quality.

• Alpha Testing Active: GSCI engineers (Terry, Tai, Dat) doing GUI and functionality review. Input/output validation begins next — verify drawings, panel books, calculations produce correct results.

Code Signing (EV)	$400/yr	Nov 2026	Optional	Instant SmartScreen trust, hardware token
Subtotal	$2,565 - $2,965

💡 Installer Tool Decision Update (Feb 25, 2026): WiX Toolset 4.x permanently sidelined. Autodesk App Store accepts compiled VLX uploads directly with a wizard-based submission process — no standalone MSI installer needed. This eliminates the WiX learning curve and development time entirely. See installer-modernization-decision.md for original analysis. (archived)

Code Signing Options Explained

Type	Cost/Year	SmartScreen Behavior	Notes
Unsigned	$0	⚠️ “Windows protected your PC” warning	OK for beta/pilot
OV (Organization Validation)	~$200	⚠️ Warning initially, builds reputation over downloads	Recommended for GA
EV (Extended Validation)	~$400	✅ Instant trust, no warnings	Requires hardware token

Staffing (2027 Q1 — Post-Revenue)

Role	Monthly	Months	Total	Status
Web Developer (Contract)	$8,000	3	$24,000	Planned Q1 2027

💡 Rationale: Defer web developer hiring until Q1 2027 to realize sales revenue from App Store launch (Dec 2026) before committing to new hires.

Top 3 Risks to Monitor:

1. R12 ARX incompatible w/ modern AutoCAD — csv.arx already fails on AC2000; need testing with modern versions

2. R9 UI/UX review reveals major gaps — alpha testers now providing early feedback

3. R17 Solo developer burnout — mitigated by being ~2 months ahead of schedule

Resolved (Feb 16-18): R1 (Source parity gap) — 12 modules recovered from v3.60. R8 (Windows compatibility) — all 5 OS platforms validated including Win10 x64 via WoW64; Win10 x64 is compatible with Win11 x64. R18 (NanoCAD) — attempted and failed, AutoCAD-only path confirmed.

Bypassed (Feb 25): R7 (WiX learning curve) — Autodesk App Store accepts compiled VLX uploads directly with a wizard. No standalone MSI installer needed.

Technical Findings: v3.60 vs v7.0 Comparison

Component	v3.60 (Legacy)	v7.0 (Current)	Gap Analysis
LSP Files	~60* (in CAB)	77 ✅	v7.0 has 17+ new modules
DCL Files	~35* (in CAB)	43 ✅	v7.0 adds 8+ dialogs
Menu Files	4 (.mnu)	5 (.cui) ✅	v7.0 uses modern format
VLX Compiled	1	1	Need recompile from LSP
ARX Binary	2 ⚠️	2 ⚠️	No C++ source either version
Installer	✅ InstallShield	❌ NONE	🔴 Critical gap
Lines (Inst.)	4,163	0	Reverse-engineered

* File counts inside CAB archives are estimates until full extraction

v3.60 Installer Bugs (Root Cause Analysis)

Bug	Severity	Root Cause	Fix Approach
User Profile detection failure	🔴 Critical	Writes to .DEFAULT/S-1-5-18 instead of HKCU	Write to proper HKCU profile
UAC file rename hack	🟢 Low	Works as Administrator; blocks standard users	Replace with process check (for non-admin)
(load "csvmenu") broken	🟡 High	Readme command doesn’t work in AC2000	Fix LISP load or automate _appload
csv.arx incompatible	🟡 Medium	ARX compiled for wrong AC version	Recompile or remove if VLX sufficient
Version key mismatch (3.2 vs 3.60)	🟡 Medium	InstallShield script never updated	Fix version constant
acad.exe crash on Vista/Win7	🟡 Medium	Menu compilation triggers crash	Pre-compile menus or skip launch
LOADCTRLS downgrade	🟡 Medium	Changes demand-load behavior	Investigate intent; preserve if needed
LocalServer32 path corruption	🟡 Low	Forward slashes in COM path	Preserve original path format
isDcc output won’t compile	🔴 Critical	Bytecode-level decompilation	Use wizard approach instead

Nero Study Findings (Feb 9):

• isDcc Limitation: Generates bytecode-level code (10,031 lines Nero, 4,163 lines CV) that won’t compile

• Workaround: InstallShield wizard generates clean 606-line .rul that compiles successfully

• Decision: Rebuild CV installer using wizard approach; each OS needs targeted build OR migrate to WiX

Multi-OS Testing Findings (Feb 10-18):

• CV3.60 installs on XP, Vista, AND Win7 — no UAC issues when logged in as Administrator

• Win10 32-bit: Full stack working — AutoCAD 2000 + CV + COM automation + auto-config script

• Win10 64-bit: Full stack working — AutoCAD 2000 running via WoW64 with Wow6432Node registry fix (103 CLSIDs, 104 Interfaces, 6 ProgIDs). Autodesk does NOT support this path — novel approach with no existing documentation, but fully functional.

• NanoCAD integration FAILED — NanoCAD doesn’t support menugroup, VLX/ARX loading, or COM automation. Only basic LSP works. Decision: AutoCAD-only path going forward.

• v3.60 source recovery COMPLETE — 12 modules recovered, 3 crash paths fixed, TB11-01x32 deployed

• Path analysis of every menu click — 40 menu-level paths + 20 panel property toggles tested end-to-end, documenting legacy architecture (menu → LSP → DCL)

• 8 bugs cataloged — see CV360-Installation-Analysis.md

• 41 files + exact registry spec — complete v11 installer blueprint

• All 5 OS platforms validated — XP, Vista, Win7, Win10x32, Win10x64

v26 Target Build Strategy

Component	Approach	Priority	Status
Source Code	Build from v11 LSP/DCL (TB11-01x32)	P1c	🟢 93 modules on disk, 20/20 toggles working
Installation	Total Uninstall (VM deployment)	P1c	✅ Working — install/remove across VMs
Installer	WiX Toolset — NOT NEEDED	—	❌ Autodesk App Store accepts VLX directly
App Store Package	VLX direct upload via wizard	P4	🔜 Planned
Web Version	AutoLISP → .js/.NET	2027	⏳ Deferred

Why different installer? InstallShield 5.x / WiX → Autodesk App Store VLX upload: InstallShield 5.x was:

• ❌ No longer supported (20+ years old)

• ❌ Not code-signable for modern Windows

• ❌ Blocked by SmartScreen/Defender

• ❌ Not compatible with Autodesk App Store

Guiding Principles

1. Prefer preservation over reinvention — Source recovery successful

2. Minimize risky rewrites — Installer rebuild, not LSP rewrite

3. Automate verification early — Regression tests in sprint weeks 4-5

4. Phased approach reduces risk — Analysis → Integration → Design → App Store
