The disciplines / 01

Many disciplines.
One coordinated handoff.

CAD Guardian carries the drawing work. TSmithCode.ai builds the software that helps it move.

A

Architecture / AEC + MEP

From floorplan to coordinated package.

Plans, sections, details, mechanical layouts, electrical documentation, plumbing coordination, and structural interfaces—prepared in native CAD and BIM workflows for professional review.

Explore AEC / MEP
P

Product / Industrial systems

From engineering intent to usable drawings.

Manufacturing drawings, equipment layouts, process documentation, BOMs, and release records. Source authority and discipline ownership stay visible through every revision.

Explore product systems

Residential renovations and additions. Commercial interiors and vertical circulation. Industrial equipment and engineered-to-order products. Professional design decisions and release remain with the responsible authority.

Sheet metal / Fabrication + assembly

Know the part.
Understand the assembly.

Sheet-metal drawing experience runs through CAD Guardian’s manufacturing work: individual parts, fabricated components, and complex products engineered to order.

Explore manufacturing support
01 / The part

Details the shop can use.

Part drawings, dimensions, sections, weld notes, and DXF outputs that keep engineering intent visible.

02 / The assembly

Show how it fits together.

Assembly views, component callouts, and bills of materials for equipment built from many coordinated parts.

03 / The handoff

Keep the package in step.

Drawing revisions, parts lists, and manufacturing outputs checked together before the responsible team releases the work.

The same practical drawing knowledge informs custom CAD software for special-build orders and repeatable production tasks.

Better together / 02

Draw it.
Code it.
Build with care.

A small world with a serious idea:
drawing intent and software execution
advance the same project.

Purple CAD Guardian carries drawings. Blue TSmithCode carries a laptop.

Data centers / a changing floorplan

Mechanical

“The new racks need more cooling. Our floorplan’s already out of date.”

Electrical

“I’ll line up power and cooling so we’re reviewing the same layout.”

Fictional conversations · September 2026 themes

Invented situations across building design, data centers, HVAC, manufacturing, and engineering software. The characters explain roles; they do not represent clients or promise project availability. Specialist roles vary by project.

Principal discipline / 03

Know what
the work requires.

Execution before expansion.

Choose the smallest reliable method. The tool serves the drawing, the system, and the person accountable for the result.

01

Draft manually

When judgment leads.

Resolve a one-off detail in the native drawing. Read the markup, preserve intent, and return it to the responsible reviewer.

02

Deterministic tools

When the rule is known.

Use templates, CAD APIs, scripts, and tests for dimensions, naming, schedules, quantities, and repeatable checks.

03

MCP connections

When controlled access helps.

Connect an approved tool to an authorized source. Keep permissions narrow, actions visible, and changes reviewable.

04

AI through an API

When a bounded task can be evaluated.

Use structured inputs and outputs, test cases, and human review for classification, extraction, and drafting assistance.

05

AI chat

When the question needs shaping.

Explore options and clarify language with permitted context. Verify the result in the native system before it becomes work product.

The guardian standard / 04

Responsibility is
in the handoff.

Know the source. Work from the authorized file and record what remains uncertain.

Protect the work. Limit access, isolate changes, and keep a recoverable version.

Earn the release. Reopen native files, inspect the output, and put it before the named reviewer.

Review public evidence

A clear first step

One drawing package.
One useful improvement.

Currently honoring an exclusive engagement. Future work begins with a defined drawing package, diagnostic, or implementation scope once availability and fit are confirmed.
