Grasshopper

algorithmic modeling for Rhino

Grasshopper 0.9.0051 is now available for download. This new release represents nearly 8 months of development so there's a lot of new stuff and also potentially a lot of new bugs. There are some major changes so please read the following carefully before upgrading:

  • Grasshopper 0.9.0051 is for Rhino5 only. It will not work on Rhino4. In fact it needs a fairly recent Service Release of Rhino5. If you don't have Rhino5 SR3 then you may consider updating Rhino first.
  • Grasshopper 0.9.0051 uses the Rhino installer engine. This means you need to manually uninstall any Grasshoppers you may currently have. You can do so via the Windows Control Panel.
  • Grasshopper 0.9.0051 may have serious bugs. Although we've tested this release in the field it is possible that it may not work under certain conditions. Please refrain from upgrading if you are on a tight dead-line.
  • Files written with Grasshopper 0.9.0051 may not read on earlier versions. Although old files should open without issue, Grasshopper is not forward compatible. Do not overwrite important files until you are certain that this release works for you.

That being said, you can download the new release from the usual location. Be sure to uninstall any old Grasshoppers first!

It is always possible to revert to the previous version if you find that this release does not work for you. Details on how to roll back to 0.9.0014 are posted here.

Ok enough hedging, on to the good stuff.

How to get rid of 0.9.0051 and revert back to 0.9.0014

In order to revert back to the previous version of Grasshopper, follow these steps.

  1. Remove Grasshopper 0.9.0051 by manually deleting the entire Grasshopper folder in your local roaming appdata. Grasshopper will be installed in %appdata%\McNeel\Rhinoceros\5.0\Plug-ins
    Type the above path into Windows Explorer as shown below and you'll see the Grasshopper folder. Just select and delete it.
  2. Download the previous version of Grasshopper (0.9.0014) from our servers and install it.

That's it.

Is there a specific reason why uninstalling of the 0.9.0051 version should be the way you described it, without the use of windows uninstaller, or any other uninstalling application?

RHI doesn't come with an uninstaller yet. I do not know when (or even if) we're planning to support this.

Hi David, the weavebird plugin do not work in the new version.

I thought it did! Can you message me the error you get?

Thanks!

Hi Guilio, the same problem.

I'm going to ask David for explanation or if he can fix this.

It did not happend in version 0.9.50. Thanks for sending this in!

We found the problem and I'll release an update later today.

Though even then WB won't work, but at least it will tell you why.
