Nora3D is AI CAD for makers, 3D printing sellers, and small product teams. Describe a functional part, refine the resulting editable B-Rep solid with prompts or CAD tools, and export STL for printing or STEP for downstream CAD. It is available across web, iOS, and Android.

Does Nora3d export STEP files?

Yes. Nora3d supports STEP export for workflows that continue in professional CAD tools, plus STL/IGES/OBJ for printing and sharing.

Is Nora3d for beginners or professionals?

Both. Beginners can start with natural-language prompts, while professionals can refine geometry and export files for production workflows.

What is the difference between editable CAD and mesh output?

Editable CAD lets you modify dimensions and features precisely. Mesh output is often harder to edit for engineering and manufacturing needs.

Can I use Nora3d on mobile?

Yes. Nora3d supports iOS, Android, and web with cross-device project continuity.

How precise are Nora3d's CAD outputs?

Nora3D produces editable B-Rep geometry with dimensions and features you can inspect and refine. As with any CAD output, check dimensions, clearances, and print settings before fabrication.

How do I upgrade my account?

Upgrading your account is very simple. After logging in, click on your avatar in the upper right corner, select Account Settings, then click Upgrade Plan.

How does text-to-CAD compare to traditional CAD software?

Traditional CAD starts with manual sketches and feature operations. Nora3D uses a prompt to create a useful first solid, then lets you refine it with prompts or CAD tools. For CAM, simulation, or enterprise PDM, export STEP and continue in your existing engineering stack.

What is the best text-to-CAD tool for 3D printing?

For 3D printing, you need a tool that outputs editable solids so you can adjust wall thickness, clearances, and fillets before slicing. Nora3D generates editable B-Rep CAD from text prompts, with STL for slicing and STEP for downstream CAD. AI usage is covered by the Starter and Pro monthly AI Credits plans; see the pricing section for the current allowance.

What do Starter, Pro, and the free trial include?

Starter costs US$9.90/month and includes 2,000 AI Credits each month. Pro costs US$18.90/month and includes 5,000 AI Credits each month. Every user receives a one-time gift of 1,000 AI Credits, valid for 7 days after they are credited. The free trial is not a monthly allowance.

Can I import existing STEP or STL files into Nora3d?

Yes. Nora3d supports importing STEP, STL, and other common 3D formats. You can bring in existing designs, continue editing with AI-assisted tools, and export back to STEP/STL/IGES/OBJ. This integrates Nora3d into your existing workflow without starting from zero.

Why Nora3D

Get past the blank canvas.
Keep the CAD.

Nora3D is the shortest path from intent to a useful first solid. It starts the model for you, then gives control back through editable features, direct CAD tools, and standard export formats.

Start from intent

Describe the part, dimensions, and constraints you care about. Nora3D turns that brief into an editable solid instead of leaving you at an empty sketch.

Keep it editable

Revise the same model with a follow-up prompt or hands-on CAD tools. Inspect critical dimensions, clearances, and fit before you manufacture or print.

Finish wherever you are

Start on your phone, refine on a tablet, or work in the browser. Export STL for printing or STEP when the job needs a heavier CAD workflow.

Complete the loop

From rough need to handoff-ready model

Nora3D handles the prompt → solid → revision → export loop. When the job moves into CAM, simulation, or enterprise PDM, hand off a STEP file to the engineering tools you already trust.

Intent-first modeling

Start with the part you need, including useful dimensions and constraints, rather than first translating intent into CAD commands.

Reusable part library

Find reusable components and common starting points for brackets, clips, enclosures, and other functional parts.

Multi-device continuity

Start a design on your phone, refine it on a tablet, and export from the browser without rebuilding the project.

Import and continue

Bring in STEP or STL files, make the supported edits you need, and export the updated model back into your workflow.

Review before export

Inspect the model and confirm critical dimensions, clearances, and orientation before slicing or downstream CAD work.

Sketch as an input

Use a hand-drawn outline as another way to communicate intent, then refine the resulting CAD with dimensions and features.

Workflow

Three steps to a useful first part
From idea to editable CAD to export

Start with the requirement. Keep control of the geometry. Finish in the tool that fits the next job.

Describe Your Part

Tell Nora3D what you want to make in plain language — or sketch it by hand

"Make a desk cable organizer with 6 slots, snap-fit base"

Generate & Refine

Nora3D builds an editable first solid — keep refining it with prompts or direct CAD tools.

Continue with dimensions, features, and fit checks

Export and Make

Export STL directly to your slicer, or STEP to continue in SolidWorks or Fusion 360.

Supports STEP / STL / IGES / OBJ formats

Built for people shipping
physical products

Nora3D helps small, hands-on teams move from a real requirement to an editable part they can print, test, and improve.

Makers & DIY Builders

Turn a replacement part, organizer, or workshop jig into editable CAD. Check the fit, adjust dimensions, and export STL to your slicer.

3D Printing Sellers

Build repeatable product variants without redrawing every SKU. Refine wall thickness, clearances, and mounting details before listing a print.

Small Product Teams

Get concepts, fixtures, and prototype parts into a reviewable solid sooner. Export STEP when the work needs to continue in your existing CAD stack.

Nora3D is for functional geometry you expect to revise. It creates an editable B-Rep solid, while visual 3D generators are usually designed for appearance-first mesh assets.

Nora3D · Editable B-Rep CAD

Modify dimensions and features precisely
Export STEP for SolidWorks and downstream tools
Hand off STEP to a downstream CAD workflow

Mesh generators · Visual 3D

Hard to edit dimensions after generation
Visual-only output, limited CAD compatibility
Better suited to characters, scenes, and visual assets

Nora3D starts and iterates the part. For complex CAM, simulation, certification, or enterprise PDM, continue in the specialist tools your team already uses.
