Import Unit/Dimension
Is it possible to import the unit/dimension of a variable from Mathcad to VBA? I understand that Mathcad stores all values in SI units, therefore, the GetValue function will always import a length dimension in units of meters. My programming, however, cycles through a list of variables (of varying dimensions) and imports their values (using GetValue) from a given Mathcad worksheet, and I would like to convert units within VBA.
The following demonstrates what I'd like to do. It would import variables of length, mass, dimensionless, or text and convert from their standard SI units to what I typically use (in, lb, dimensionless, and text):
McadValue = WS.GetValue(VariableName)
Select Case WS.GetDimension(VariableName) <--- is there something equivalent to GetDimension?
Case “Length”
Mult = 39.3701 ‘Convert meters to inches
Case “Mass”
Mult = 2.20462 ‘Convert kg to lb
Case “Dimensionless”
Mult = 1
Case Else
Mult = 0 <--- I use this for text fields, I can modify as necessary if text is handled differently.
End Select
If Mult = 0 Then
vbValue = McadValue ‘for variables which contain text
Else
vbValue = McadValue * Mult ‘for variables which contain numeric values
End If
I searched some other threads and only found discussions of trying to obtain a variable’s unit. I do not need the unit, just the dimension.
Please let me know if anything like this is possible (I realize if it exists, it’s probably not in as nice of a format as I’d like, so I’ll need to make some modifications to my example script above).
Thank you in advance.
