Why PAK 3D
Powerful enough to build. Simple enough to enjoy using.
Professional CAD tools should help you turn ideas into geometry—not make you fight the software first.
Real CAD workflows
Create precise sketches, build parametric solid features, refine geometry, and keep the complete modeling history visible in the Part Navigator.
No complicated installation
Open PAK 3D in a supported desktop browser and begin modeling without installing or maintaining a traditional desktop CAD package.
Built around fair pricing
Professional design tools should be accessible to individual engineers, students, makers, and small teams—not only large companies.
Modeling tools
A structured path from precise sketches to finished solid models.
PAK 3D combines familiar parametric modeling concepts with a focused browser workspace designed to keep tools understandable and accessible.
Sketch & dimension
Choose a datum plane or solid face, create profiles, and define geometry with precise dimensions and editable sketch entities.
Build solid features
Create extrudes, revolves, sweeps, patterns, merges, and cuts with controlled values and clear previews before committing.
Refine geometry
Apply fillets, chamfers, draft, shell, mirror, trim body, and face operations through guided feature workflows.
Construction & control
Use datum planes, selection filters, feature settings, and a visible Part Navigator to keep the model organized.
Model exchange
Bring in STEP geometry, export STEP solids through OCCT-backed tools, or create STL output for mesh-based workflows.
Recovery & feedback
Encrypted recovery autosave, tracked support tickets, and diagnostic feedback help protect work and improve the beta experience.
Model exchange NEW
Continue your work with STEP and STL export.
PAK 3D is built around real solid-model workflows. Export your model for downstream CAD use with STEP, or create STL output for mesh-based manufacturing and review.

Our mission
CAD should expand what people can create—not limit who gets to create it.
Professional CAD software has become increasingly expensive, difficult to access, and unnecessarily complicated to learn.
We believe powerful design tools should be available to more people.
Our mission is to build a capable CAD platform that is easier to learn, easier to access, and fairly priced—without removing the precision and structured workflows engineers depend on.
PAK 3D is being developed independently for engineers, makers, students, educators, and small teams. During our closed beta, we are working directly with a limited group of early users to improve the platform, refine its workflows, and decide which tools matter most.
The software should help you build your model—not become the hardest part of building it.
PAK 3D Closed beta
Help us build a better CAD experience.
PAK 3D is currently being tested with a limited group of early users.
Closed beta members receive access to the current modeling tools and can directly influence future workflows, features, and development priorities through their feedback.
