Grasshopper 2 Vs Grasshopper 1

Grasshopper
1

I would like to know if I can translate all the definitions I did with Grasshopper 1 into Grasshopper 2.
I must wait for GH2 to have all the commands of GH1 or GH2 working differently, and I can now translate all my GH1 definitions to GH2.
Thanks a lot,
Roy

the simple answer is no. GH2 is still in development so not all the functionality is available, and because it uses different data structures and adds multi-threading, it will break quite a few plugins. The good news is that it seems you’ll be able to have both GH1 and GH2 installed in parallel, so you won’t lose your work

Hi Adel,
I was supposing this after a few tests.
I don’t use Grasshopper plugins because I don’t want to be attached to a plugin of a plugin with relative upgrades and plugin issues (just my opinion, of course). I will wait for the full GH2 release and sometimes make some other tests.
Have a great day,
Roy

GH2 can run GH1 components in special container components. This requires Grasshopper 1 to be loaded first, so it’s not a great solution. Also, due to differences in data types and metadata, the interoperability between both versions will always be imperfect.

You can try and open a GH1 file (or copy-paste components from GH1 to GH2, or drag components from the GH1 panels onto GH2) to see how that works. As time goes on more and more auto-upgraders will be added which convert components into their GH2 equivelents, but this too will never be a perfect conversion.

Hi Genius,

Thanks for your message.
I am not particularly concerned about the direct translation from the GH1 definition to GH2.
Can I rewrite the same definitions (rewriting them from the start and following the new GH2 philosophy) with GH2 as I did with GH1?
Just one example: I haven’t found the command “Seam” of a curve in GH2. Do I need to wait for the version of this command to be released, or is there already another way to obtain the same result in GH2?
Thanks again,

Roy

Hi Roy -

As David wrote, you can use the GH1 Seam component in GH2:
