Grasshopper Start

Hi ,

I have started using grasshopper last week and a I have finished a couple of training sessions online. I was wondering is there any project based learning websites or tutorials out there ? ( Learning by solving some kind of problem)

I also have a problem with data tree and data management if there is any tutorial to articles to explain it , I would greatly appreciate that.

Also check youtube, there are a lot of videos explaining data trees, even by David

Thanks for the quick response. I am checking it out now.
