I had to do it more than once.
All the time my PC couldn't show any Port in the Arduino program: Tools -> Ports (Ports was displayed in grey)
I got this error: "COM 6 does not exist" in firefly
So it was obviously the USB connection. My flatmate told me that Windows USB Ports seem to have this problem of not recognizing devices more often...
Hope that was helpful,
cheers…
owing error has been raised: System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {CE7E6869-6F74-4E9D-9F07-3DCBADAB6299} failed due to the following error: 80040154 没有注册类 (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)). at System.Runtime.Remoting.RemotingServices.AllocateUninitializedObject(RuntimeType objectType) at System.Runtime.Remoting.Activation.ActivationServices.CreateInstance(RuntimeType serverType) at System.Runtime.Remoting.Activation.ActivationServices.IsCurrentContextOK(RuntimeType serverType, Object[] props, Boolean bNewObj) at System.RuntimeMethodHandle.InvokeMethod(Object target, Object[] arguments, Signature sig, Boolean constructor) at System.Reflection.RuntimeConstructorInfo.Invoke(BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture) at Microsoft.Scripting.Interpreter.NewInstruction.Run(InterpretedFrame frame) at Microsoft.Scripting.Interpreter.Interpreter.Run(InterpretedFrame frame) at Microsoft.Scripting.Interpreter.LightLambda.Run3[T0,T1,T2,TRet](T0 arg0, T1 arg1, T2 arg2) at System.Dynamic.UpdateDelegates.UpdateAndExecute2[T0,T1,TRet](CallSite site, T0 arg0, T1 arg1) at Microsoft.Scripting.Interpreter.DynamicInstruction`3.Run(InterpretedFrame frame) at Microsoft.Scripting.Interpreter.Interpreter.Run(InterpretedFrame frame) If upper error is:1) "Retrieving the COM class factory for component with CLSID…" then try the following fix: a) Close Rhino. Restart your PC. Once the PC boots up, double click on the "regMapWinGIS.cmd" file in "MapWinGIS" installation folder. When it closes the Command Prompt window it opened, try running Rhino, Grasshopper and the component again. b) If the upper COM class error appears again, then close Rhino, and uninstall the MapWinGIS application. It is advisable to do that with an application which does that by removing not only the installation files but also the leftover files (like those from registry). For example, use the: Revo Uninstaller Pro. A free 30 days full working version can be downloaded from: http://www.revouninstaller.com. After the Revo Uninstaller Pro uninstalls MapWinGIS, install it again, but this time by running the installation file by right clicking on it, and choosing: Run as -> Administrator. After the installation is complete double click on "regMapWinGIS.cmd" file in "MapWinGIS" installation folder. When it closes the Command Prompt window it opened, try running Rhino, Grasshopper and the component again. If after this the COM class error appears again, then post a question about this issue at: http://www.grasshopper3d.com/group/gismo/forum. 2) If the upper error is not "Retrieving the COM class factory for component with CLSID…", please post a question about this issue at:http://www.grasshopper3d.com/group/gismo/forum.…

created surface with sweep and rotate them with number of division. Section curves of 2Railsweep is defined with 3 Point arc and shape is also controlable.
You can change shape by sliding 16 paramteters.
The definition is rather long, hope somebody can modify with more sphiscated manner.

パラメトリックにボトルデザインをする.ghxファイルを作成しました。ボトルのプロファイルカーブを、参照となる円に対して、高さ、シフト、オフセットでコントロールポイントの位置情報を与えて定義。次にスイープで分割数だけ回転コピーして作成。
スイープの断面、3点円弧で作成し、形状コントロールするようにしています。
ボトル形状は、16のパラメーターをスライドすることで定義出来ます。

variables - all doubles. I call them pc, max, min. The expression is very simple: (pc*(max-min))+min I tried either with the F(x)3 component or the F(x)n with 3 inputs, the expression editor in F(x)n gives me the warning "invalid, expected ( instead of -"I then tried naming the variables x,y,z and it seems to work with either component... so, what am I not understanding here? Thanks for any light you can shed... --Mitch…
