How it works

From description
to reviewed CAD model.

Describe what you need to create or modify. Inspect dimensions, feature operations, and geometry. Make the final decision.

YOUR REQUEST

“Add four M4 mounting holes around this motor face. Preserve 2.5 mm minimum edge distance.”

MODEL CONTEXT

Selection: Motor interface
Keep: Base + support ribs
Hole type: Clarify before planning

This example resolves “M4” to Ø4.5 mm through clearance holes.

The complete workflow

Eight steps.
One accountable decision.

Each stage makes the next one inspectable. Review the full process from initial prompt to finalized model.

Open

An explicit starting state

Begin with the model you already have.

Open an existing model in a supported host CAD environment. Existing features, dimensions, and interfaces establish the starting state. Host support is still to be confirmed.

Select

Geometry and reference context

Give the request a precise reference.

Select a face, feature, or component. The selection connects engineering intent to the relevant geometry and helps define what should stay unchanged.

Describe

Structured engineering intent

State the outcome and the constraints.

“Move this connector 8 mm inward, preserve the mounting pattern, and maintain at least 3 mm wall thickness.” State the result you need, along with the limits that matter.

Resolve

Explicit assumptions and open questions

Make meaningful ambiguity visible.

An M4 hole could mean a tapped hole or a clearance hole. The intended workflow asks the questions that affect the change, and keeps uncertain inputs visible.

Plan

A reviewable change plan

Inspect the proposed feature operations.

Review dimensions, references, constraints, dependencies, feature operations, and required checks before proceeding. A readable plan connects the request to the proposed CAD change.

Execute

A native, editable proposed state

Let native operations do the geometry work.

The intended implementation translates the resolved plan into deterministic operations inside a host CAD system. Execution produces a proposed state for inspection; it is not final acceptance.

Inspect

A before / after diff and check results

See both the visual and semantic difference.

Compare changed features, dimensions, references, and assumptions. Review the scope of geometry and engineering checks, their warnings, and anything still unresolved.

Decide

An explicit engineering decision

Accept, revise, or reject the change.

You decide whether the proposal meets the engineering intent. Accept a reviewed change, revise the request, or reject the proposal and preserve the original model.

Two modes for design control

Create quickly.
Refine when needed.

Explore lets you test alternatives and compare shapes quickly. Compile resolves the exact dimensions, tolerances, and constraints required before manufacturing.

Exploring

What if this interface moved?

Compare possible geometry changes while keeping uncertain inputs visible.

Investigate alternate positions
Compare an existing and proposed state
Identify constraints that need clarification

OPEN QUESTIONS ARE EXPECTED

Revision is part of the process.

Inspect the geometry, adjust the prompt, and review the updated model. Your original CAD stays preserved until you approve.
