Surface Modeling Features

  • Convert Phi models to Onshape Part Studios

    Send your Phi models to Onshape part Studios, live updates, export to STL or STEP.

  • Import reference models and reference sketches

    Import reference models from Onshape or STL, and sketches to use as reference.

  • Import and edit Onshape designs

    Import Onshape Part Studios, or parts of them, and edit them within Phi

Curve-based modeling

Simply draw natural free-form curves reflecting your design intent, and Phi automatically and interactively calculates the surfaces.

Top quality surfaces

Phi generates top quality, watertight and smooth surfaces. Ease of modeling is combined with engineering quality, bridging artistic design with precise engineering.

Intuitive design

Intuitive, easy and effortless modeling. Phi enables everyone to freely design and manipulate 3D shapes in a fraction of the time.

Cloud/browser based

Phi is fully on the cloud and runs on web browsers on any platform at interactive speeds.

Real Interoperability

Offers essential interoperability with other CAD systems (and 3D printers) by supporting several standard file formats.

Testimonials

Wow, That was a great Webinar with amazingly fast manipulations of shapes. Once again the Onshape Team has shown the future of design tools with a serious time saving piece of software, Phi! Keep up the great work, team Onshape!

Ron van Dijk, RD Consulting, Project Management | Product Development

A wonderful tool. I'm myself a software engineer and worked on intuitive modeling tools. I haven't got the chance to test Phi thoroughly but from what I've already experienced I like it. I was on the look for a fluid, organic surface modeler that integrates well with my current OnShape design workflow. And Phi could be the answer. The products that I design revolve around music instruments and ergonomic input devices for computer interaction (for sculpting, modeling and character animation - ergonomic keyboards, trackballs, connected puppets).

Andrei Moraru, CEO - CTO, Poppet

Being part of the Beta testing for Phi freeform has been a great experience. First, Phi’s CAD freeform approach is powerful and versatile. And being cloud based means no installation with access from anywhere; combined with Onshape integration, Phi is a path to organic shaped, engineered parts. The Phenometry team has put together an outstanding UI, training materials, and they quickly respond to any questions or concerns with in depth explanations and hot fixes if needed.

Bruce Williams, Founder of Accurate Pattern, Inc.

Phi + Onshape was a really neat work flow experience. Onshape provides steady parametric dimensions while Phi gives you the freedom to create complex shapes by simply dragging or clicking the model. The freedom Phi gives the user while maintaining a solid model is unmatched.

Michael Pascoe, Cache River Mill, Design Engineer

Absolutely insane tool.
