Grasshopper 0.8.0001 available for download

Dear Everybody,

the first version of the Grasshopper 0.8 series is available for download. The reason we rolled the minor version number is because clusters are available again (yay).

I'm off to work with the core McNeel team in Seattle for about 2 months tomorrow and I wanted to release this before I left. It's a bit rushed, clusters are definitely not as 'finished' as I'd like them to be, but there should be enough there for some good old customer feedback at least.

Just in case I horked something up, you can still download 0.7.0057 here.

Download 0.8.0001 from the usual location.

First a basic new features and bug list, then the warning section. If you don't read the warning section you forfeit any rights to complain about this new release.

● Added a new Cluster Object. This is very young code, expect big (quite possibly breaking) changes in the future.

● Added auto-panning to Drag Object and Draw Wire interactions.

● Added canvas curl UI for drag+drop options.

● Added default values to the Quad-Face and Tri-Face components.

● Added a Tree Split component for separating out branches.

● Drag+Drop with text content now creates a new Panel.

● Curve data can now convert from a Surface/Brep with a single closed edge loop.

● Added runtime message balloon feedback.

● VB and C# script components now update immediately when typehints are changed.

● VB and C# script components now update immediately when input parameter access is changed.

● MoveForward and MoveBackwards arrange options are now available.

● Added a Grasshopper Version field to the status bar.

● GraphMapper can now adjust intervals, points and vectors in addition to just numbers.

● Parameter disconnection menu items now highlight the connection in question on mouse-over.

○ The menu short-cuts for Find and Move Forward were both Ctrl+F. Find is now F3.

○ Any Undo operation would wreck the Redo stack, this no longer happens.

○ Fixed a bug with automatic tooltip resizing.

○ Fixed an erroneous "app" autocomplete member in the C# and VB script members.

○ Fixed a bug in the CurveCurve intersection SDK code that occured with overlaps.

○ Fixed a bug in the PointList display component with stale point data.

○ Fixed a nasty bug with stale document caches and undo/redo.

○ Custom Preview Meshes would always draw wires regardless of the Grasshopper view setting. This is fixed.

The Aforementioned Warning Section

This pertains mostly to clusters. At present there's no way yet to edit the contents of a cluster. You can make clusters from a selection by clicking on the toolbar cluster button (selected objects remain on the canvas, this will change), or by drag+dropping ghx files onto the canvas and selecting the Cluster Insert mode from behind the curl.

Clusters contents can be opened as new documents via the Cluster object menu, but this code is very icky still. You can edit cluster properties by double clicking on one.

It is entirely possible that clusters will change so much in the near future that old clusters might not read correctly from 0.8.0001 files. Do not use them yet on production work and always make backups.

That's it. Enjoy,

David

Hello David,

Can I somehow install gh8 without reinstalling addons to the previous versions?

Hi Alexandre,

yes, it is in theory possible to have multiple versions of Grasshopper available. You should manually copy all the files in the Grasshopper install folder to a safe place, then install the new version.

When you start Rhino you can drag+drop the desired GrasshopperPlugin.rhp into Rhino to load the one you want.

The installer itself doesn't take long to run though, so you could also choose to have both installers available and run one if you want to switch version.

Hehehehe, today I've started a GH workshop at Monzón 8. My students have now to think again about Gh possibilities with cluster :)

Thanks for this great work.

Hi David

Many thanks for reinstating the cluster and also the panning facility. Although the cluster system
will change in the future, I can presumably expand the cluster using the version of grasshopper that created it, then install the new version and then doing the re-clusterisation process.

Hi David,

I wanted to report what seems like bug with the new .8.0001 version. When I create a new plane I right click on the component and click "Manage Plane collection". I then try to set the Origin to 12=X 12=Y 1=Z. However, it will not let me set the Z Origin. It will switch Y=1 and Z will not change. Side Note: I have the X,Y,Z "3D vectors" set to 1. Perhaps I am doing something wrong. Thank you for your time.

Yup, totally hosed. I'll fix it. Thanks for reporting.

Hi,

is the planes bug just a "manage plane collection" issue or are the plane components in v.8.01 generally corupt?

It's a bug inside the UI of the Collection Manager. Planes should be fine.

Hi David,

Thanks for the new release!

1. The auto-panning is great, but it doesn't work "leftways"
2. Is there a way to explode a cluster in this version?

and by the way:
3. Since recently, grasshopper crashes (taking down rhino with it) everytime I hover over the "Recent Files" option in the File menu. This happened also with the previous version. Any idea what could be triggering it?
