Grasshopper 0.8.0011 available for download

Hi All,

Grasshopper 0.8.0011 can be downloaded from the usual location. But before you do, a small notice and a warning:

In order to run this new version you need to have the latest Microsoft runtimes installed on your machine. If you're on the Rhino5 auto-update cycle you should already have these. Install the new version, and if it doesn't work, then also download and install this package:

Microsoft Visual C++ 2005 Service Pack 1 (be sure to pick the x86 version as Rhino4 is a 32-bit application)

This build won't run well on Rhino5 until the next release of Rhino5. And secondly this build contains dlls compiled with a newer platform. This should not technically matter, but don't download this build if you're worried something exotic might go wrong. In case something does go wrong, the installer for 0.8.0010 can still be downloaded here.

Changes since 0.8.0010:

Object Info marker location is now limited to the visible canvas region.
Added a Ctrl+Alt+Shift override to save the Grasshopper window + info markers as an image. (Danny, I know you'll like this)
Added Modified Arc component (Curve.Primitive dropdown).
Added Point/Circle tangent lines component (Curve.Primitive dropdown).
Added External Tangent Lines component (Curve.Primitive dropdown).
Added Internal Tangent Lines component (Curve.Primitive dropdown).
Added Find Similar Member component (Sets.Sets dropdown).
Beefed up GHA loading error messages.
Added early custom Ribbon Layout mechanism and editor.
Added Geometry Cache object (Params.Geometry dropdown).
Added automatic closed, planar curve to mesh conversion.
Added MeshSplit component (Intersect.Boolean panel).
Added type groups to the GHA info dialog.
Output parameter naming for Tree Explode was inconsistent, this is fixed.
The Value List object has an improved selection UI.
Intersect.Boolean panel has been renamed to Intersect.Shape.
Loose curve offset algorithm has been completely rewritten, expect possible breaking changes.

Further notes:

Loose curve offset did not work properly on Closed and Periodic curves. I rewrote the thing from scratch but it probably gives quite different (hopefully better!) results. There are still further improvements possible, so it's possible it will change behaviour again soon.

Ribbon Layouts are customized collections of tabs, panels and buttons. They are stored in *.ghlayout files which can be created using a dedicated Layout Editor. You can start the editor via the Grasshopper File menu or via the Ribbon popup menu (you have to right click on the area of the ribbon where tabs are displayed).

The order of Tabs and Panels is maintained, but within each panel area the components are ordered alphabetically.

When multiple loaded *.ghlayout files define the same Tab or Panel names, these will be merged. Duplicate components in identically named panels will not be shown.

The editor itself is almost entirely drag+drop based, so you won't find many buttons or menu items that 'do' stuff.

Layout settings should be sticky between Grasshopper sessions. If no layouts are loaded or if all loaded layouts are hidden, then the default layout kicks in, showing all components. So the only thing you can do with these custom layouts is hide functionality.

Enjoy!

Danny clearly has the "Show All Component" option checked in the View menu, which forces all icons to be drawn on the ribbon anyway.

I forget this isn't standard

Thank you David. However, i used grasshopper foк about 2 years, and i know aout drpodowns. I cannot show drpodown and "about" window at rhe same time, so here are few screenshots showing that all components and stuff exept "find similar member" are shown.

You have a lot of gh plug-ins there's probably a conflict

That is most odd. Can you use the canvas search for "similar", see if it shows up there?

Also, select the following code and drag+drop it into Grasshopper, what do you get?

This code becomes text on a panel

Ok, so we can safely say that the component is ignored by Grasshopper for some reason. It's not just missing on the ribbon, it's also missing in the component database.

If the loading of an object fails there is usually an error message. I assume there is no error window during loading, so how about the command history? Anything in there that might shed light on this?

Another possibility is that Grasshopper ignores the component for a good reason, in which case there will not be an error message. This would mean that the Mathematics.gha file somehow got corrupted, but instead of just making it fail, it got corrupted in a very specific way (the odds are definitely against this happening).

Let's check the Mathematics.gha file to see if there's anything fishy about it. It should be exactly 509,952 bytes in size and you can use this online utility to create an MD5 hash of the file. It should be: c8f8bba432a5ba8d1ec8b1873dac6112

You can find Mathematics.gha in <ProgramFiles>\Rhinoceros 4.0\Plug-ins\Grasshopper\Components

If you find a difference, try re-downloading and re-installing.

Hi Phillip,

Try uninstalling my plugin(s) (from control panel), reinstalling Grasshopper and then reinstalling my plugins. This has come up for a small set of users when updating Grasshopper. I haven't determined any reason for this occurring and without replicating it is very difficult to resolve. It happened only once for me, and not always even for the same user, and I don't see how loading my plugin could prevent native grasshopper components from loading.

Let us know if it fixes it or not.

Cheers,

Jon

Mathematica had a size of 506 368 kb after all installations. I don`t knopw why but it wasnt rewritten during the installation. I had to remove it manually, then reinstall grasshopper. Now everything is ok,'thank you guys

oh so nice! editing layouts, thank you! but my user panel is all blank?

Hi Ryles,

Blank how? Is there nothing at all visible in the editor? You have to make these layouts from scratch, so the only initial stuff you (should) get is a single tab and a single empty panel.
