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

In my vista machine it is working very well. Did you tried to drag a grasshopper file from windows explorer to upper left corner of a grasshopper window? It's very nice addition I must say.

After installing 0.8 nearly all gh tools are gone. Anyone else had this problem?

Hi Wieland,

I take it you're not getting errors during loading?

Can you post a screen-shot of the window from the _GrasshopperDeveloperSettings command? I'd like to see all the folders that are involved in loading.

Hi David,

I did not get any errors during loading. I now uninstalled Jon plug-in because this made problems before and the reinstalled GH 0.8 but now GH does not start at all and I get this error message:

I'm sorry I can't make that out except for the fact that it's in German.

If this is caused by running an uninstaller, the most likely explanation is that something messed up the file and folder structure. Try uninstalling and reinstalling grasshopper.

This is weird: I reinstalled ssi and now gh starts again but with no icons:

Permalink Reply by Jon Mirtschin on October 31, 2010 at 10:13am

The disapearing icons has been associated with my plug-ins before, I have absolutely no idea why. My installer (and uninstaller) certainly does not tamper with Grasshopper files, it only adds specific .gha files.

There's known issues with COFF loading, but it should only result in my components not being shown, not propagate out to native grasshopper components.

If we can isolate out what the scenario or situation is that causes this, I'd be more than happy to find a fix for it, but I saw this issue only once about 8 months ago and can't repeat it. Uninstalling the plug-in from the control panel should not leave any trace of the previous installation.

Hi Jon,

I just downloaded your latest version and installed it. Now GH 0.8 works fine ever without reinstalling GH.

Thanks, Wieland
