In 2019 and 2020, I worked on a virtual playground to make and share Grid Kit designs. We wanted to make Grid Kit fun and understandable for anyone, even before you have any physical beams.
Have a play with a prototype Grid Beam sandbox!
The prototype works, but we learnt building a 3D interface is no easy feat. Rather than designing a full CAD (computed-aided design) application, we decided to start with a catalogue of designs and let the user adjust parameters (height, width, etc.), which is actively developed at gridkit.nz/ideas.
