Linking a Text Parameter from part to assembly

[Anonymous]

In the past, if I wanted to pull a parameter from a part to an assembly I have used code similar to the following:

Parameter("Part", "Length") = Assembly_Length

Currently I'm trying to use the same code to pull through a text parameter, however I receive the following error:

"Object reference not set to an instance of an object."

Is there another bit of code that allows you to pull a text parameter through?

Please upload your code as txt file

The text file should be attached.

What I'm actually trying to do is pull text parameters from an assembly to a drawing. In the assembly I have a form where you can input basic dimensions and customer info, and I want to push the text info to a custom title block on the drawing.

To me, it looks like you have things backwards then.

Variable to assign a value to = VALUE to assign to the variable to the left

is how it works.

What your code is currently doing is PULLING from the active document ("Architect" on the right means that it's READING "Architect from the active document"), and what you want to do is PUSH. So if PUSHING values to the assembly, from each document is what you're after, then your code is correct, but if you are wanting to run from the assembly and pull from sub documents, you need to rethink your ordering.

The code I provided was from the drawing, so it was pulling the parameter from the assembly. This should be correct, unless I'm understanding your statement backwards.

Just like your single line of posted code in the original statement adds the parameter value to the PART specified before the equals sign, what the code you have attached in the text file is CURRENTLY trying to do is add parameters from the drawing into the assembly. This means you have all of your equations written backwards.

If the parameters on the right side of the CURRENT equations don't exist in the drawing, you would likely be getting errors for said reason.

@Anonymous,

Try the below iLogic code to pull parameters from assembly and custom iProperties in drawing document. Need to run below iLogic in drawing document.

doc = ThisDrawing.ModelDocument

'Below code is to pull parameters from a document which is referenced in drawing document
ARCHITECT = Parameter(doc.DisplayName, "ARCHITECT") 
CUSTOMER_CONTACT = Parameter(doc.DisplayName, "CUSTOMER_CONTACT") 
DOOR_NO = Parameter(doc.DisplayName, "DOOR_NO")
DRAWING_NO = Parameter(doc.DisplayName, "DRAWING_NO")
ENTRANCE = Parameter(doc.DisplayName, "ENTRANCE") 
FINISH = Parameter(doc.DisplayName, "FINISH") 
JOB = Parameter(doc.DisplayName, "JOB") 
LOCATION = Parameter(doc.DisplayName, "LOCATION")
MAT_CEILING = Parameter(doc.DisplayName, "MAT_CEILING") 
MAT_ROOF = Parameter(doc.DisplayName, "MAT_ROOF") 
MAT_WALLS = Parameter(doc.DisplayName, "MAT_WALLS") 
MAT_WINGS = Parameter(doc.DisplayName, "MAT_WINGS")
MODEL = Parameter(doc.DisplayName, "MODEL") 
ORDER_NO = Parameter(doc.DisplayName, "ORDER_NO")

'Below code is to create custom propeties in drawing document
iProperties.Value("Custom", "ARCHITECT") = ARCHITECT
iProperties.Value("Custom", "CUSTOMER CONTACT") = CUSTOMER_CONTACT
iProperties.Value("Custom", "DOOR NO.") = DOOR_NO
iProperties.Value("Custom", "DRAWING NO.") = DRAWING_NO
iProperties.Value("Custom", "ENTRANCE") = ENTRANCE
iProperties.Value("Custom", "FINISH") = FINISH
iProperties.Value("Custom", "JOB") = JOB
iProperties.Value("Custom", "LOCATION") = LOCATION
iProperties.Value("Custom", "MAT'L CEILING") = MAT_CEILING
iProperties.Value("Custom", "MAT'L ROOF") = MAT_ROOF
iProperties.Value("Custom", "MAT'L WALLS") = MAT_WALLS
iProperties.Value("Custom", "MAT'L WINGS") = MAT_WINGS
iProperties.Value("Custom", "MODEL") = MODEL
iProperties.Value("Custom", "ORDER NO.") = ORDER_NO
