NXOpen Help!!!

NXOpen Help!!!

NXOpen Help!!!

(OP)
I'm having a lot of trouble finding documentation that clearly explains input for functions. For example the NXOpen.Features.HelixBuilder. I created the code below with the help of the recorder and it works, but I can't find any documentation on how to input a value to "SizeLaw" for example you have to write it as "helixBuilder1.SizeLaw.Value.RightHandSide = r1*2"

The documentation section below has the most I could find:
https://docs.plm.automation.siemens.com/data_servi...

''''''''''''''''Create Helix''''''''''''''''''''''''''
Dim nullNXOpen_Features_Helix As NXOpen.Features.Helix = Nothing
Dim helixBuilder1 As NXOpen.Features.HelixBuilder = Nothing
helixBuilder1 = workPart.Features.CreateHelixBuilder(nullNXOpen_Features_Helix)

helixBuilder1.SizeLaw.Value.RightHandSide = r1*2
helixBuilder1.PitchLaw.Value.RightHandSide = "15"
helixBuilder1.EndLimit.Expression.RightHandSide = "1"

Dim myHelix As NXOpen.NXObject = Nothing
myHelix = helixBuilder1.Commit()

The recorded journal BTW had 10X the number of lines. I just kept deleting them and making sure it still ran.

RE: NXOpen Help!!!

The SizeLaw.Value is an expression object. The .RightHandSide (formula) for the expression is entered as a string. This article shows how to create various types of expressions (including simple values and formulas). The code is in VB, but the process is the same in Python.

I fixed the problem by creating the Datum with the code below. Still not sure why the other creation method produced the issue but I'm moving on.

Dim wcsMatrix As NXOpen.Matrix3x3 = workPart.WCS.CoordinateSystem.Orientation.Element
Dim myPlane As NXOpen.DatumPlane = workPart.Datums.CreateFixedDatumPlane(CenterPt, wcsMatrix)
