What I did to get 32-bit Rhino to recognize the Grasshopper installation was to drag the RHI file to the 32-bit rhiexec.exe (located in C: Program Files Rhinoceros 5.0 (64-bit) System x86 in my case). Now both versions of Rhino can open the Grasshopper installation. I hope this helps anyone else. Open Rhino and type 'Grasshopper' into the command line (without quotations). Wait for grasshopper to load. Install GHPython 0.6.0.3 by downloading the file here and drag the.gha file onto the Grasshopper canvas. Select and drag all of the userObject files (downloaded from Food4Rhino) onto your Grasshopper canvas.
In this video we'll walk through downloading then installing orupdating Grasshopper.The main website for the Grasshopper plugin is www.grasshopper3d.com Hereyou can find examples, tutorials, lots of other great resources forworking 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 usto the McNeil Rhinoceros website where we do the downloading.
And here we'll be prompted for an email address soI'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, sohere 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, buttechnically there is still a proprietary license associated with the software, soit 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 Iwant to install grasshopper for just me, or for anyone who uses this computer?I'm going to go ahead and click on install Grasshopper foranyone 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 inGrasshopper and this launches a separate Grasshopper window.Later in the interface video, we'll cover the different ins andouts 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 froma 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 programfiles 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 orupdating Grasshopper.In the next videos we'll take a look at working in the interface.
