iLogic Parameter value is wrong

[Anonymous]

Hi guys!

Can't use the parameter value in a formula because it sends the wrong value.

The value will show as the wrong one if it's alone but combined with the unit it's good.

There's something I must be missing.

Made a dummy assembly for you guys to have a look

Thanks

Hi.

Grabbing parameters VALUES will always return the value in DATABASE UNITS.

As far as length goes, the value returned will be converted to cm. So you need to write in your code to convert it back.

Good luck,

so lenght is Always in cm,

angles are Always in Radians

Mass in Kilogram

Time in second

temperature in Kelvin...

ways to convert:

oUM.LengthUnits = UnitsTypeEnum.kInchLengthUnits

Dim slon222 As Double = oUM.ConvertUnits(oUM.GetValueFromExpression(oCD.Parameters.UserParameters.Item("LONGUEUR_MAITRE").expression, UnitsTypeEnum.kInchLengthUnits), "cm", "in")

Dim slon223 As Double = oUM.ConvertUnits((oCD.Parameters.UserParameters.Item("LONGUEUR_MAITRE").value), "cm", oUM.LengthUnits)

GetValueFromExpression   will Always give a value in cm.

specifying a unittype is only usefull if the expression has no unit.

Late reply years later but figured this could help someone in the future

I was able to simply add a mathematical express at the end of my original value being returned and it did indeed work.  I needed my value in inches but was getting it in CM.  So I just added "/2.54" since 1In = 2.54CM.  

See my code for full context of how I used this within my own application, in which I needed to append material parameters to my filename after running a For Each loop where each file is saved as a separate DXF

Dim oCompDef As SheetMetalComponentDefinition = oDoc.ComponentDefinition
Dim THK As String = "_" & oCompDef.Parameters("d0").Value.ToString/2.54 & ".dxf"
