Hello
I want to be able to change the value of global variables in equations. (As shown in attachment)
I know how to add by this method:
Dim swEquationMgr As Object
Set swEquationMgr = swModel.GetEquationMgr
swEquationMgr.Add -1, """Mass [kg]""= ""SW-Mass""/100"
How do I modify one that has already been created?
Thank you
Hello
Here's an example from the SolidWorks VBA help:
'Modify dimension equation at index, 1, in all configurations
longEquation = swEquationMgr. SetEquationAndConfigurationOption(1, """D1@Boss-Extrude1"" = 0.07", swAllConfiguration, Empty)
If longEquation <> 1 Then ErrorMsg SwApp, "Failed to modify a dimension equation"
http://help.solidworks.com/2014/english/api/sldworksapi/Add_Equations_Example_VB.htm
And a question on this topic about SolidWorks formum talks about it, it uses a split to separate the equation into 2 :
For i = 0 To swEqnMgr.GetCount - 1
vSplit = Split(swEqnMgr.Equation(i), " = ")
vSplit(0) = Replace(vSplit(0), Chr(34), Empty)
If vSplit(0) = VARIABLE_NAME Then _
swEqnMgr.Equation(i) = Replace(swEqnMgr.Equation(i), vSplit(1), NEW_VALUE)
Next i

Just for my personal culture...
I don't really understand what Jean bapt means by modifying values?
If I click on one of the values, I can change it to my liking...
I'd just like to understand this question and its purpose =) (why do vba etc...)
As I have no basis in APIs, I think my misunderstanding comes from there. ^^
Thank you!
@Bart: either it has to modify several files en masse, or its overall value changes according to other parameters internal to the part or assembly or according to an external list (Excel file for example).
My goal is to assemble parts in an assembly and set the height, width, length, and thickness when importing.
This is the best solution I have found.
That is to say that on a Userform I enter all this data and I modify it in the equations.
Yes, that's the question I asked a few months ago, except that I didn't get a clear answer^^
I understand me.
I made an assmebling, and in it I put all my equations that interact in the rooms.
The only thing is that I have to click on the sides to change them... And the rest follows, but on, a useform would be + appropriate I think.
I'm in 2012 and there are functions that SW doesn't know.
Like SetEquationAndConfigurationOption for example
In:
'Modify dimension equation at index, 1, in all configurations
longEquation = swEquationMgr.SetEquationAndConfigurationOption(1, """Height"" = 50", swAllConfiguration, Empty)
If longEquation <> 1 Then ErrorMsg SwApp, "Failed to modify a dimension equation"
This link is really not clear...

I get to this code that doesn't work.
Sub Test()
Dim swApp As SldWorks.SldWorks
Dim Part As SldWorks.ModelDoc2
Dim swModel As SldWorks.ModelDoc2
Dim swEquationMgr As SldWorks.EquationMgr
Dim i As Integer
Dim vSplit As Variant
Const VARIABLE_NAME As String = "Height"
Const NEW_VALUE As String = "50"
Set swApp = Application.SldWorks
Set swModel = swApp.ActiveDoc
Set swEquationMgr = swModel.GetEquationMgr
For i = 0 To swEquationMgr.GetCount - 1
vSplit = Split(swEquationMgr.Equation(i), " = ")
vSplit(0) = Replace(vSplit(0), Chr(34), Empty)
If vSplit(0) = VARIABLE_NAME Then _
swEquationMgr.Equation(i) = Replace(swEquationMgr.Equation(i), vSplit(1), NEW_VALUE)
Next i
End Sub
thank you for your help

Hello
I don't know Sw, I work under invent
Why not go through an excel sheet that will calculate the dimensions and SW will only have to update it.
I don't see the point of going through macros (unless you don't have excel).
I set up complete stairs in excel sheets and each piece of inventor updates it with this sheet.
Thank you
In which line do you encounter an error?
Franck:
Adding the entry of an excel sheet would make the system more complex and I don't want to make it heavier.
All this is done from a Userform to make it more interactive.
The thing is that there are no bugs, the macro is realized and nothing changes...
Try removing the _ from the line:
If vSplit(0) = VARIABLE_NAME Then _
and puts
swEqnMgr.Equation(i) = Replace(swEqnMgr.Equation(i), vSplit(1), NEW_VALUE)
on the next line, followed by an "End if"
Then put a stop to this line
swEqnMgr.Equation(i) = Replace(swEqnMgr.Equation(i), vSplit(1), NEW_VALUE)
Does your macro stop?
Otherwise, you have to go through all the values of your vSplit(0) for example with a debug.print or more with a msgbox!
So it works haphazardly...
I noticed that when I go in the management of equations, if the cell activated is for example: =90 of the height. I put OK to close the box.
I run the macro and I get in my msgbox:
Height (i.e. what is sought)
and Length = 70
Width = 95
...
(example on attached image)
If it's the =70 of Length I get Height = 90 and Length
Current Code:
Const VARIABLENAME As String = "Height"
Const NEW_VALUE As String = "70"
For i = 0 To swEquationMgr.GetCount - 1
vSplit = Split(swEquationMgr.Equation(i), " = ")
vSplit(0) = Replace(vSplit(0), Chr(34), Empty)
MsgBox vSplit(0)
If vSplit(0) = VARIABLENAME Then
swEquationMgr.Equation(i) = Replace(swEquationMgr.Equation(i), vSplit(1), NEW_VALUE)
End If
Next i
Maybe a syntax problem?
Try an lcase (lowercase = lowercase) or ucase (uppercase = uppercase) for your two variables, either
VARIABLENAME and vSplit(1).
And you can put an else to your yew to put a breakpoint there and see in which case it doesn't work.
I didn't quite understand how to write the code...
Like this?
VARIABLENAME = LCase(lowercaser = lowercase)
I sorted the name of vSplit(0) into Nom_eq so that I had Height and not Height = 90
Here's my code
NB = Len(VARIABLENAME)
For i = 0 To swEquationMgr.GetCount - 1
vSplit = Split(swEquationMgr.Equation(i), " = ")
MsgBox vSplit(0)
vSplit(0) = Replace(vSplit(0), Chr(34), Empty)
Nom_eq = Left(vSplit(0), NB)
If Nom_eq = VARIABLENAME Then
swEquationMgr.Equation(i) = Replace(swEquationMgr.Equation(i), vSplit(1), NEW_VALUE)
'MsgBox vSplit(1)
Else
End If
Next i
But I have a bug that is displayed on the line
swEquationMgr.Equation(i) = Replace(swEquationMgr.Equation(i), vSplit(1), NEW_VALUE)

Hi all.
message1/2:
A little in a macro can make it unusable! JB, I looked at your macro and the grain of sand is in the code snippet [vSplit=Split(swEqua.equation(i), " = ")] and more specifically in [" = "].
Explanation: The equations of a SW model are alphanumeric strings, and, like all strings, they can be manipulated by VBA functions present in Word, Excel, Access, .... and SW.
For your code, the Split function will take the content of the ith equation [swEqua.equation(i)], split it in two at the level of [" = "], then as vSplit is a Variant, vSplit(0) will be automatically assigned to the left of [" = "] and vSplit(1) will be automatically assigned to the right of [" = "].
It is for [" = "] that the bottom hurts, because a SW equation can be ""D1@Ext"=50+20" as well as ""D1@Ext" = 50 + 20" or ""D1@Ext" = 50 + 20". I write this word with a word processor and when using it, I always ask for non-printable characters to be displayed. This allows me not only to see but also to count the four spaces on either side of the equal sign of the writing of the last equation (the one above). SW, he doesn't care or rather manages these superfluous or non-present spaces. Conclusion, the manipulator can add an equation by leaving droppings (double, triple spaces) but you will have to deal with it, and above all, take into account this thorny problem in your programming (your code). In another message my code reviewed, expanded and commented out in the form of a Sub (function) with the name 'ChangeVariableValueInQuaAndRebuildPart' which you call here with another Sub with the name 'try01'. The function 'ChangeVariableValueInQuaAndRebuildPart' requires two arguments that I named 'VarName' and 'ValVar'.
Note: I am attaching in another message a test piece to be opened (it contains the dimensions "D1@Ext" and "D1@Esq".

Hello again, here is my code and the test part as an example
Sub essay01()
ChangeVariableValueInQuaAnd RebuildPart "D1@Ext", "80"
ChangeVariableValueInQuaAndRebuildPart "D1@Esq", "44.6"
End Sub
Sub ChangeVariableValueInQuaAndRebuildPart(NomVar as String, ValVar As String)
Note: an equation is an alphanumeric string and is treated as such with the usual VBA functions.

Hello Maxime,
Your program works great!
What I want to do is more modify the variables to lighten the changes (attachment)
In the meantime I managed to get my code to work:
Sub management ()
'Height
Nom_cote = "Height"
Val_cote = UserForm1.TextBox2.Value
Call Test
'Width...
'Depth...
'Thickness...
End Sub
Sub Test()
Dim swApp As SldWorks.SldWorks
Dim Part As SldWorks.ModelDoc2
Dim swModel As SldWorks.ModelDoc2
Dim swEquationMgr As SldWorks.EquationMgr
Dim i As Integer
Dim vSplit as Variant
Dim NB As Integer
Dim Nom_eq As String
Dim OLD_VALUE As Integer
Set swApp = Application.SldWorks
Set Part = swApp.ActiveDoc
Set swModel = swApp.ActiveDoc
Set swEquationMgr = swModel.GetEquationMgr
NB = Len(Nom_cote)
For i = 0 To swEquationMgr.GetCount - 1
vSplit = Split(swEquationMgr.Equation(i), " = ")
vSplit(0) = Replace(vSplit(0), Chr(34), Empty)
Nom_eq = Left(vSplit(0), NB)
OLD_VALUE = Right(vSplit(0), Len(vSplit(0)) - InStrRev(vSplit(0), "="))
If Nom_eq = Nom_cote Then
swEquationMgr.Equation(i) = Replace(swEquationMgr.Equation(i), OLD_VALUE, Val_cote)
Else
End If
Next i
boolstatus = Part.EditRebuild3()
End Sub
As I explained, it works, but I'm afraid that this hacking will be limited.
and thank you for your help on the different forums!
Hi JB,
Why make it complicated when you can make it simple!
Sub management ()
Bottom Height Management
if Test "Height",UserForm1.TextBox2.Value then
boolstatus = Part.EditRebuild3() 'If Test returns True then Rebuild Part
else
msgbox "Problem"
end if
' Rq: click behind the 't' in Test and type a space to see that Test requests, in a tooltip, two arguments separated by a comma (help with the prog.). In this way, Test can be in another module without any problem.
'Width...
'Depth...
'Thickness...
End Sub

Dim swApp As SldWorks.SldWorks

Dim i As Integer
Dim vSplit As Variant
Set swApp = Application.SldWorks
Set Part = swApp.ActiveDoc
Set swModel = swApp.ActiveDoc
Set swEquationMgr = swModel.GetEquationMgr
Test=False
For i = 0 To swEquationMgr.GetCount - 1'Know that with each interchange, swEquationMgr.GetCount - 1 is recalculated. It's better to use a local variable like in my macro
vSplit = Split(swEquationMgr.Equation(i), "=") ' I removed the spaces on each side of the equals sign!!
vSplit(0) = Replace(vSplit(0), Chr(34), Empty) 'I substitute the quotation marks contained in split(0) with nothing
vSplit(0) = Replace(vSplit(0), Chr(32), Empty) 'I substitute the spaces contained in split(0) with nothing (I can, because the name of a dimension is necessarily a string without spaces!!)
If Split(0) = VarName, Then
swEquationMgr.Equation(i) = Replace(swEquationMgr.Equation(i), Split(1), ValVar) 'I replace Split(1) (the value of the variable NomVar with the value ValVar.
Test=True
