C# Component: Keyboard Shortcuts, More Than One Editor Instance, Missing a Console

I've been getting up to speed with the C# scripting component and have a few questions/suggestions (coming from a GHPython component experience): 1) Does the C# component have any keyboard…Continue

GHPython Some Bottlenecks (Bugs?)

Hi Giulio and Steve, I've recently noticed a couple of bottleneck with the GHPython component which can quite severely impede on performance. Thought I would bring them up here so as to hopefully…Continue

Geometry Parameter: Vector being cast to Point

When you pass a Vector3D through a Geometry parameter it is cast to Point3D. Seems like a bug to me. See attached file. Best, AndersContinue

Mesh Analysis GHPython Components

Hi All,



I'm currently in the process of wrapping my head around GitHub. Seeing as how I'm now back in academia I thought this might be a good chance to share some code, for once :)

Many thanks Anders,

I used xlrd and xlwt it works but its a bit tricky. I'll try the .NET methods.

cheers

Hi Anders,

Do you know how can I open and excel sheet in python grasshopper, add some line to the sheet, save and close it!

Thanks

Hi Anders, thanks for the reply. I checked that already it says if it is cylinder but I'm looking for a way to find out an easy way to pre-rationalize sub-surfaces which are not cylinder but close to cylinder so I can convert them to cylinder surface later! if it make any sense to you . . .

Hi Anders;

Do you any easy and basic way to check if a double surface cab get converted into cylinder surface? Basically for fabrication to check if I can reduce the cost by converting few double curved panel and get more or less the same result!

many thanks!

Many thanks Anders;

I figured that out, now I'm looking for way to convert text to one single curve (to save time for laser cutting). At the moment i get the out line of text as curve which is great but still time consuming.

Regards,

H/

here is the complete one:

if(!string.IsNullOrEmpty(face) && size > 0 && !string.IsNullOrEmpty(content) &&
pl.IsValid)
{

var te = RhinoDoc.ActiveDoc.Objects.AddText(content, pl, size, face, bold, italics);
Rhino.DocObjects.TextObject txt = RhinoDoc.ActiveDoc.Objects.Find(te) as Rhino.DocObjects.TextObject;

if(txt != null)
{
var tt = txt.Geometry as Rhino.Geometry.TextEntity;
A = tt.Explode();
}

RhinoDoc.ActiveDoc.Objects.Delete(te, true);

Hi Anders;

Do you know how can i convert  this c# code into python? The goal is to creat single curve text for laser cut:

RhinoDoc.ActiveDoc.Objects.AddText(content, pl, size, face, bold, italics);Rhino.DocObjects.TextObject txt = RhinoDoc.ActiveDoc.Objects.Find(te) as Rhino.DocObjects.TextObject;

thanks . . .

Hi.

Of course. Thanks for reply. I'm using conditional check. It helps more and as you said easier to figure out where the problem is.

Thanks,

Hej man,

I found it again, seems like to solve my problem i just need to post my question on your wall :D . ..

Hi anders,

I'm trying to split curves in python and i get this eror:

Runtime error (TypeErrorException): Parameter must be a Guid or string representing a Guid

Im sure its Guid!!!

here is the simple script:

import rhinoscriptsyntax as rs
import Rhino as rc
curve01=rs.coercegeometry(x)
curve01.Domain = rc.Geometry.Interval(0,1)
print (rs.CurveDomain(curve01))
a=rs.SplitCurve(curve01,y)

ay idea!

Thanks.
