Join Chris Reilly for an in-depth discussion in this video Downloading and installing Grasshopper, part of Learning Grasshopper.
In this video we'll walk through downloading then installing or updating Grasshopper. The main website for the Grasshopper plugin is www.grasshopper3d.com Here you can find examples, tutorials, lots of other great resources for working with Grasshopper. I would especially recommend the discussion forum, this is really useful. I even used it to get some references when I was putting this course together. So let's look at how to download Grasshopper. Here under the download link, I want to look for the latest version. At the time of this recording, the latest version was 1.0. So I'm going to click on this latest version link and this actually jumps us to the McNeil Rhinoceros website where we do the downloading.
And here we'll be prompted for an email address so I'm just going to talk in my email address. And then click next to go to the download section. Now the file I'm going to download is an RHI file. And it's going to be labelled with a version number, something like 0.9.005. Let's go ahead to the downloads folder and see what I have got, so here is my Grasshopper plugin, 0.9.75.0, so that is the build information. Grasshopper is distributed as freeware, so there is no charge to download it, but technically there is still a proprietary license associated with the software, so it is not actually open source, but it is free.
And it doesn't work on its own, it only works from inside of Rhino. So at the time of this recording, Grasshopper only runs on Windows operating systems. Even though Rhino is becoming cross-platform, to use Grasshopper with Rhino, we have to run Windows. So we're in Windows, we've got our Grasshopper download. Now to do the install, I just need to double click on the RHI file, and that will open up the Rhino package installation wizard. And here I'll be prompted for a couple different options, it's asking me if I want to install grasshopper for just me, or for anyone who uses this computer? I'm going to go ahead and click on install Grasshopper for anyone who uses this computer, and just click next.
Okay our installation completed successfully. I'm just going to close out of this. Let's go ahead and launch Rhino and get Grasshopper running. So once we have Rhino up and running from the command line I can just type in Grasshopper and this launches a separate Grasshopper window. Later in the interface video, we'll cover the different ins and outs of working between Grasshopper and Rhino. But for now, we've got it installed, we've got it running, so that's great. Now just a couple more tips, if you were upgrading Grasshopper from a previous version, there's one additional step you would want to take. I'm just going to close out of Grasshopper and close out of Rhino. If I were upgrading from a previous version I would want to look under program files on the C drive, under common files, under McNeil, under Rhinoceros, under Version 5.0, under plugins I would find a folder like this, Grasshopper and then a big string of letters and numbers. I would just want to delete that folder before I ran the install process.
If I had a previous version of Grasshopper installed. So, that's pretty much it as far as downloading, installing or updating Grasshopper. In the next videos we'll take a look at working in the interface.
