Coding challenge.. PLS HELP

So I wrote a script that loops changes in parameters on sheets and title blocks and printing them. The problem is it prints without any errors and the parameters look fine. but the parameter graphics don’t get updated
see it used to work. but all of a sudden it stopped working.
here is the code( the major piece of it)

for BuildingNo,bldgDirection,Angle in zip(BuildingNoValue, DirectionValue, AngleValue):
	TransactionManager.Instance.EnsureInTransaction(doc)
	theSheet[0].SetParameterByName("BLDG. NO.", BuildingNo)
	theSheet[0].SetParameterByName("UNIT ORIENTATION", bldgDirection)
	elem = UnwrapElement(TitleBlock[0])
	parameter = elem.LookupParameter("NR - ANGLE")
	debuglist.append(parameter)
	parameter.Set(Angle)
    TransactionManager.Instance.TransactionTaskDone()
	y = TitleBlock[0].GetParameterValueByName("NR - ANGLE")
	debuglist.append(y)
	PrintView(doc,theSheet,pRange, printerName, combined, filePath,printSetting)
OUT = debuglist

Think you’ll need to commit the transaction before you print. Swap the 3rd to last line with the second to last line and see if that works.

excuse me it was like that before. still no luck. i will update the script in question. thanks!

Can you post the full code including the print view definition? Need to see which api methods are in play, as my guess is a doc regenerate is needed but can’t know without the context.

Hello,
try to regenerate the current document with doc.Regenerate() during the process


# some code
for BuildingNo,bldgDirection,Angle in zip(BuildingNoValue, DirectionValue, AngleValue):
    TransactionManager.Instance.EnsureInTransaction(doc)
    theSheet.SetParameterByName("BLDG. NO.", str(BuildingNo))
    theSheet.SetParameterByName("UNIT ORIENTATION", str(bldgDirection))
    elem = UnwrapElement(TitleBlock)
    parameter = elem.LookupParameter("NR - ANGLE")
    debuglist.append(parameter)
    parameter.Set(int(Angle))
    y = TitleBlock.GetParameterValueByName("NR - ANGLE")
    debuglist.append(y)
    TransactionManager.Instance.TransactionTaskDone()
    doc.Regenerate() ## <- Add Here
    PrintView(doc,IN[7],pRange, printerName, combined, filePath,printSetting)
# rest of code

it works for another file but not for a similar one with the same parameters

try to call the PrintView function outside the loop at the end


# some code
TransactionManager.Instance.EnsureInTransaction(doc)
for BuildingNo,bldgDirection,Angle in zip(BuildingNoValue, DirectionValue, AngleValue):
    theSheet.SetParameterByName("BLDG. NO.", str(BuildingNo))
    theSheet.SetParameterByName("UNIT ORIENTATION", str(bldgDirection))
    elem = UnwrapElement(TitleBlock)
    parameter = elem.LookupParameter("NR - ANGLE")
    debuglist.append(parameter)
    parameter.Set(int(Angle))
    y = TitleBlock.GetParameterValueByName("NR - ANGLE")
    debuglist.append(y)
TransactionManager.Instance.TransactionTaskDone()
doc.Regenerate()
PrintView(doc,IN[7],pRange, printerName, combined, filePath,printSetting)
# rest of code

your code is difficult to understand:

  • some input variables are unused
  • content of input lists is unknown (empty list?)
  • why you use a for loop to set parameters for one sheet?
  • does your input titleblock correspond to the input theSheet?

the best is to share an example of file (if possible) too
