AI-first workflows vs traditional CAD
QuantCAD, an AI-first CAD platform, is fastest at turning requirements into a first B-rep model and changing it by description. Traditional CAD tools such as SolidWorks, Fusion or NX give finer control over constraints, drawings and tolerances. Many teams start in QuantCAD, export STEP, and finish the detailing in their CAD tool.

How do AI-first CAD and traditional CAD compare?
| Task | AI-first (QuantCAD) | Traditional CAD |
|---|---|---|
| First model | Generated from a text description, without CAD skills. | Built feature by feature by someone trained in the tool. |
| Changes | Describe the change in chat. Each change becomes a revision. | Edit sketches, features and constraints directly. |
| Constraints and GD&T | Not the focus today. Finish them in your CAD tool. | Full control over constraints, datums and tolerances. |
| Drawings | Not available in QuantCAD today. | 2D drawings and manufacturing documentation. |
| Output | B-rep solids, exported as STEP (AP242) and STL. | Native files, plus STEP, STL and other exchange formats. |
| Skills needed | Plain language and the dimensions that matter. | Training in the specific CAD package. |
When is AI-first CAD faster?
- Creating a first baseline model from requirements.
- Iterating on dimensions and features by describing them.
- Exploring several variants before committing to one.
- Prototypes and internal reviews where speed matters more than drawings.
When does traditional CAD do the job better?
- Final detailing with strict parametric constraints.
- Drawings, GD&T and manufacturing documentation.
- Large assemblies with mature mates and BOM workflows.
- Specialist work such as CAM and simulation.
What does a hybrid workflow look like?
- 1Describe the part or assembly in QuantCAD and generate a baseline.
- 2Iterate on the key features and dimensions until the shape is right.
- 3Export STEP and import it into your CAD tool for final detailing and documentation.
Frequently asked questions
Is AI CAD meant to replace traditional CAD?
For most teams it is a complement. QuantCAD gets you from requirements to a first B-rep model quickly and lets you iterate by description. Traditional CAD remains the place for detailed constraints, drawings, GD&T and final manufacturing preparation.
Where is prompt-to-CAD fastest?
Early ideation, prototypes, and the first solid baseline of a part or assembly, especially when the requirements can be written down as dimensions and functional constraints.
What does a hybrid workflow look like?
Generate and iterate the baseline in QuantCAD, export a STEP file, then import it into SolidWorks, Fusion, Onshape, FreeCAD or another CAD tool for final detailing and documentation.
Can I open QuantCAD models in SolidWorks or Fusion?
Yes. QuantCAD exports STEP (AP242, millimetres), which opens as solid bodies in SolidWorks, Fusion, Onshape, FreeCAD, Inventor, CATIA, NX and other CAD tools.
