VBA Macro TO Export Splines from catia to text file(.dat)
VBA Macro TO Export Splines from catia to text file(.dat)
(OP)
Hello every one!! I am sort of new to the whole VBA thing. so i was wondering if i could get some help here. so basically i am trying to find out how to write a dat file that wiil be able to import splines into Catia. These splines when imported are supposed to act like meshes on a structure, that is, picture a meshed structure, but instead of mesh it will be splines on it. so right now i thought to learn a macro that exports a few splines i created on a structure into a text(.dat) file. but i have been having troubles with the macro i have as it asks me to select a spline, but wont allow me to click on the spline in spec tree. The thing is that i have lots of splines and i would like the macro to just select splines automatically without asking and export them..... PLS HELP ME. thanks alot.
the code is written below:

RE: VBA Macro TO Export Splines from catia to text file(.dat)
I only took a look at 3D section so:
What kind of object do you have in 3D? Isn't it a HybridShapeSpline? If yes, then
CODE -->
If you want to avoid user interaction, just collect them from Specification Tree in your own collection and parse that collection.
Something like this:
CODE -->
Sub Splines() Dim oPart As Part Set oPart = CATIA.ActiveDocument.Part Dim mySplines As Collection Set mySplines = New Collection Dim oHybridBody As HybridBody Dim oHybridShape As HybridShape For Each oHybridBody In oPart.HybridBodies For Each oHybridShape In oHybridBody.HybridShapes If TypeName(oHybridShape) = "HybridShapeSpline" Then mySplines.Add oHybridShape End If Next Next Dim mySpline As HybridShapeSpline For Each mySpline In mySplines 'do your stuff here Next End SubHope it helps.
RE: VBA Macro TO Export Splines from catia to text file(.dat)
mysel.Clear
Set QuCtrlP = oSpline.EndPoint
QuCtrlPRaw = QuCtrlP.Name
QuCtrlPSemi = Split(QuCtrlPRaw, " ")
QuCtrlPFin = QuCtrlPSemi(1) - 1
ReDim Preserve CtrlPoint(QuCtrlPFin)
For j = 0 To QuCtrlPFin
Set CtrlPoint(j) = oSpline.GetItem("Ktrl-point." & j + 1)
CtrlPoint(j).GetCoordinates oCoordinates
A.WriteLine ("point" & j + 1 & "X / Y")
A.WriteLine (oCoordinates(0))
A.WriteLine (oCoordinates(1))
A.WriteLine ("")
Next
End If
And also could someone tell me how to change the part where it asks me to select the spline so that it just automaitcally selcts all splines in the code? "Selection = mysel.SelectElement2(otype3D, " Please select the spline ", False)"
RE: VBA Macro TO Export Splines from catia to text file(.dat)
CODE -->
does not return the expected array. Put a breakpoint on the line above and Watch the value of QuCtrlPSemi
Did you really create the script you posted? Because you are asking some basic questions in obvious contradiction with the coding skills shown above.
If I would have the time I would recreate it for you but I don't.
