# CAD Guardian

> AEC, MEP, drawing coordination, and engineering software.

CAD Guardian is the independent technical practice of Thomas Smith. Architecture and Product are the two primary paths: AEC and MEP drawing coordination, sheet-metal and engineered-to-order documentation, and the CAD software that supports delivery. TSmithCode.ai provides the detailed software profile. CAD Guardian is currently honoring an exclusive engagement; inquiries concern future fit and require availability and conflict review.

## Core positioning

- Enter the existing system before proposing replacement.
- Preserve trusted behavior and operator knowledge.
- Return a bounded, reviewable increment early.
- Keep completed work, open questions, assumptions, risks, and the next checkpoint visible.
- Close with native files, tests or QA evidence, known limitations, and an identified version.

## Capabilities

- C#, .NET, SQL, desktop applications, APIs, access controls, deployment, support, and legacy modernization
- VBA, Access, and Excel migration into maintainable enterprise systems
- AutoCAD, Inventor, Revit, Vault, and related Autodesk API development
- Drawing, BOM, metadata, validation, and release workflows
- Sheet-metal and fabrication drawing experience: part details, sections, weld notes, DXF outputs, assembly views, and parts lists
- Residential renovation and addition documentation; commercial interior and vertical-circulation drawing support
- Complex engineered-to-order assembly documentation and custom CAD software for special-build workflows
- Production dashboards, queue controls, requirements mapping, and Pareto prioritization
- Technical strategy connecting software, CAD, data, operators, and organizational decisions

## Public evidence

Public evidence is deliberately limited to career aggregates, authorized statements, licensed context, and clearly labeled synthetic examples.

- 14+ years across CAD, software, and operations
- 439+ production drawings completed in a six-month prior role
- C#/.NET as the primary enterprise development stack
- Autodesk API experience across AutoCAD, Inventor, Revit, and connected workflows

These statements do not disclose client or employer artifacts and do not imply endorsement, current availability, or a guarantee for future work.

## Privacy boundary

The site does not publish client or employer names, addresses, drawings, models, code, invoices, payment records, emails, transcripts, recordings, credentials, or employment and onboarding data without written authorization.

Independent work is screened for confidentiality, intellectual-property, scheduling, and conflict obligations before acceptance. The first conversation requires no confidential files.

## Contact

Email: tsmithcad@gmail.com

A useful first message includes only the organization or team, existing system or drawing type, bounded problem, responsible reviewer, target date, and success condition. Do not attach confidential files to the first message.

## Drawing and software discipline
CAD Guardian supports AEC and MEP drawing workflows, model coordination, manufacturing documentation, and native review packages. TSmithCode.ai is the supporting software practice. The site construction scene is fictional; no client plans or models are used. Tool selection distinguishes manual drafting, deterministic automation, authorized MCP connections, evaluated AI API tasks, and AI chat. Professional design and final release remain with the responsible authority.
