GHPython Content From AECtech+ Barcelona Workshop

Hi All, I ran a short GHPython workshop at the AECtech+ event in Barcelona. I used this GitHub repository for sharing files with the workshop participants, and thought I’d share all the content here as well.

We will demonstrate, explore, and combine these overlooked features th…
