SketchUp modelling mastermind Eric Lay shows off a great technique to quickly model a gyroid in SketchUp. Eric also shared the SketchUp file with the steps to modelling included in an easy to follow scene-based file.
Eric (aka Boofredlay on the forums) has been using SketchUp since version 3. He is one of the original moderators for and has contributed to SketchUcation from the very beginning. By trade he is a 3D artist and architectural draftsman.
