Read File Component Time to Read File

I am using the read file component to read in a text file (Grashopper Version 0.8.0066). I originally had the text file on the local hard drive and it only takes the component a few milliseconds to complete. However the files recently moved to a network drive and it now takes 4 minutes to complete (according to the profiler). It is a very small (2kb) text file and opens up in a program like notepad very quickly from the network location. Is there something about the component function that…See More

"Thank you for explaining that the .Item() call returns a copy. Explains why the .length property call worked in the previous line for what I was using it for and the .Unitize() method didn't work, which was why I was so confused.…"

David Rutten replied to Larry Boxler's discussion Unitize a vector

"Vectors are value types, when you call: S_MidVector.Item(i), you get a copy of the vector that's inside the list. Unitizing this copy won't affect the original vector. What you need to do: Dim vec As Vector3d =…"

"I did try that, but the vectors don't come out Unitized. The component output still has the initial length vectors. "

"just do S_MidVector.Item(i).Unitize() instead of S_MidVector.Item(i) = S_MidVector.Item(i).Unitize() ;)"

Unitize a vector

I have the following code in a grasshopper VB.Net Script component: Private Sub RunScript(ByVal S_Vector As List(Of Vector3d), ByRef S_Mid As Object) Dim S_MidVector As New List(Of Vector3d) Dim i As IntegerFor i = 0 To S_Vector.Count - 2 S_MidVector.Add((S_Vector.Item(i) / S_Vector.Item(i).length) + (S_Vector.Item(i +_ 1) /S_Vector.Item(i + 1).length)) S_MidVector.Item(i) = S_MidVector.Item(i).Unitize() NextS_Mid = S_MidVectorEnd SubI get an error saying that type…See More

Running Excel Macro from VB Component

I have a VB script component that opens an excel spreadsheet, populates some cells with data and then calls a macro to run. This all works fine except that I get a warning box with the following message a few seconds into the macro running on excel (the excel macro isn't complete yet when the message comes up, but does continue to completion). …See More

"Hi Larry, it's been so long since I used the Legacy SDK that I'm totally rusty. Any reason you can't switch to RhinoCommon? To answer your question, an OnBrep is an IOnBrep. IOnBrep is an interface, OnBrep is a class…"

VB.net component using Solid Intersect function

I am trying to write a vb.net component (using the vb.net compatibility version of the component) that does the solid intersection function. I am having trouble understanding how to take the input Breps and convert them to IOnBreps for use in the RhinoBooleanIntersection command. Below is my code so far: Private Sub RunScript(ByVal BR1 As OnBrep, ByVal BR2 As OnBrep, ByRef A As Object) Dim bresult As Boolean = False'Code here to take BR1 and BR2 and create IOnBreps to pass to boolean…See More
