Create Empty Sheets Revit 2020

Packages

Does any one know how to get this :point_down:t2: to work for Revit 2020?

CreateEmptySheets.dyn (27.4 KB)

It works for Revit 2019.2, but not for Revit 2020.2.

This is what i get in Revit 2020.2.

[0] [0] Traceback (most recent call last):

  • File “”, line 56, in *
    AttributeError: ‘ViewSheet’ object has no attribute ‘ViewName’

[0] [1] Empty List

Had to change the inputs to not get warnings.

Revit 2019.2
2020
Revit 2020.2

Hi @bvs1982,

The property ViewName has been removed in Revit 2020. Just replace “ViewName” by “Name” .

try:
		errorReport = None
		a=ViewSheet.Create(doc,i)
		a.Name=n
		a.SheetNumber=u
		sheets.append(a.ToDSType(False))

Thanks for you response, but that didn’t fix it for me.

NB
I hate changes like these. I am getting the hang of Dynamo and nowthey gonna
f*** me over with stuff like this :unamused:.

EDIT
Fixed. I removed the refresh from the node earlier. Shouldn’t have done that.
I put it back and now it works! Thank you again @Alban_de_Chasteigner.
Not the first time you have been my savior.

Seems to work for me (Revit 2021) :

Sheets
Sheets808×616 36.4 KB

The sheet numbers must be strings.

The custom node updated :
Tool.CreateEmptySheet.dyf (24.6 KB)

Bit off-topic.
As Packages / nodes aren’t allways updated for all the different Revit versions. Is there i place i can find information about these changes so i can fix nodes
myself? i.e. ViewName to Name. So i don’t have to create a topic for stuff like this.

You have to look in the Revit API.
For example for this obsolete property :

Hi Alban,
I am a newbee looking at the Revit API and could use a little help, as it all looks very cryptic. I looked at your link here:

But I dont see anywhere it tells you to switch a.ViewName = n to a.Name=n I can see that ViewName was deprecated. but how did you know to fix it with a.Name?

Also, is there anywhere that explains how to read the Revit API, I have looked at it many times, but still really cant understand where to look to get information that I need to write code. I have looked at some code that I knew worked, went into the API to see if I could figure out how it looked in there and couldnt figure out the correlation. Is there some document somewhere that explains how to read the API in laymens terms?

@mix

It is in the Syntax thingy.


 We suggest you use ‘Element.Name’ property instead")]

Ahh so a.Name acts as a variable. a is = Element?
