Having a problem with the excel read component. 

I get this error message...

System.NullReferenceException: Object reference not set to an instance of an object.
at Grasshopper.Kernel.GH_Component.GH_StructureIterator.SetDataTree(Int32 index, IGH_DataTree tree) in C:\dev\grasshopper\1.0\root\src\GH_StructureIterator.vb:line 1296
at LunchBox.WF_ExcelReadNew.SolveInstance(IGH_DataAccess DA)

why and how to fix...

Has anyone used the new machine learning components? I don't really know where to start with them, but I want to learn.

hey,

I am trying to write a script that tesseltes regular hexagons across a surface using the hexagon cells panel. So that no matter the input surface/rectangles dimensions- those hexagons are as close to regular as possible. I know that the width-to-height ratio of a hexagon resting on a side is 2*sqrt(3)/3 (to calculate number of U to v tiling) but I fail to understand the t-parameter and I'm unable to attain the regular hexagons. Can you help?

best

Dear all,

Thanks for all of the continued interest. To be honest, I haven't been keeping tabs on this group as much as I would like since I've started my new business.

I have released a new version of LunchBox over at Food4Rhino that you might be interested in checking out.  The new version is provided as a ClickOnce installer as well as a ZIP file containing the latest plugin files. Hopefully by providing both it is easier for everyone to get up and running.

Enjoy!

-Nate

Hi, can anyone see my discussion(a bout Lunchbox) here

it is about random quad panels which go out of the base surface around corners?

The read/write excel components aren't working for me. They were working even yesterday, but today I get this error:

System.Runtime.InteropServices.COMException (0x800A03EC): Exception from HRESULT: 0x800A03EC
at Microsoft.VisualBasic.CompilerServices.LateBinding.LateGet(Object o, Type objType, String name, Object[] args, String[] paramnames, Boolean[] CopyBack)
at LunchBox.WF_ExcelRead.SolveInstance(IGH_DataAccess DA)

Any thoughts? Thanks!
