A careful pair of hands
for your CAD work.

The work between an idea and a finished model often means repeating small, careful steps. Structura brings a task brief, a visible plan and controlled actions into the CAD environment you already use.

You can ask an advisory question, prepare a plan or explicitly start an approved task. Those are separate actions. Saving a brief or reviewing a plan does not start CAD work.

Brief a bounded change

For example: “Add a 3 mm fillet to the outside edges of the selected part, preserve the mounting holes and prepare a STEP export.” The assistant should establish the selection, constraints and checks before acting.

That is an illustrative workflow. Availability depends on qualification of the application, version and task.

Bring your own AI provider

With your own provider account, the prompts and selected images you share travel directly from the desktop to the provider you choose. Provider credentials use encrypted local storage protected by your operating system. The provider's terms govern how it handles that context.

Advisory questions can use the brief alone. Visual CAD tasks use fresh context from your environment. Decide what project information your practice permits you to share before starting a task.

Choose a starting model

We recommend GPT-6.1 Sol at medium reasoning as the practical starting point for this beta. Set a provider spending limit and test a small, reviewable task in your CAD setup.

In beta.2, optional Clef-flash fast CAD inspections use text context to choose an approved read-only inspection. This setting is off by default and needs your own Cloudflare account and API token. You fund its usage through Cloudflare, alongside your main AI provider. Hosted MadeVia AI credits are not enabled in the beta.

Your Happy Webs account

Happy Webs manages your beta workspace and desktop access. Its account service does not receive project screenshots, prompts, provider keys or model responses. Hosted MadeVia AI credits are planned for later and are not included in the beta.

Inspect the model after a change. Check dimensions, units, configurations, warnings and any effect on related features before accepting it. The assistant's result does not replace your design review.

You and your team retain responsibility for calculations, standards, material choices and deliverables. Release to manufacturing, quotations, orders and final exports need the approval appropriate to your workflow.

A task can pause when the scope is unclear or the result cannot be verified. That checkpoint is useful information for the engineer reviewing the work.

The beta has no MadeVia subscription charge. Sign in through Happy Webs and bring your own AI key. Your provider bills you for its usage.

Future pricing starts at £49 per seat per month, excluding VAT. Optional plans will add a monthly MadeVia AI credit allowance. Any future subscription will be an explicit purchase through hosted Stripe checkout, separate from beta sign-up.

Explore reviewed workflows for structural engineers, bounded drawing and modelling tasks for CAD professionals, and beta access and data boundaries for engineering practices.

For provider setup, read our AI model guidance for the CAD beta. Your provider bills usage separately from the free beta.
