Place existing view on existing sheet issue [null]

Packages
1

I read several threads about problem of placing views on sheets but none seems to help me. I wanted to do simple thing for start - get a specific sheet and place a specific view on it. No luck… :frowning: I get null output - anyone knows what’s going on here?

Hi,

Quick questions :

  • Are you in Manual mode ? If so, have you hit Run ?
  • What version of Dynamo are you using and which version of Dynamo is supported by this package ?
  • Could you try to copy and paste the content of the custom node in your graph and running it ? It may help to see where the problem is encountered.

Yes, I did run it. 1.3.2

Sorry, maybe I was unclear. Can you paste this Python script on your .dyn and directly connecting the inputs to it ? The Python node will certainely output an error and we will see where it is bugging :slight_smile:

Ok, to be sure - I placed Python node, pasted the code there and added two more inputs.

The error I get is:

Warning: IronPythonEvaluator.EvaluateIronPythonScript operation failed.
Traceback (most recent call last):
File “”, line 30, in
TypeError: iteration over non-sequence of type Sheet

p.s.

Does it mean it expect lists?

p.p.s.

Ok, so I created lists for input but now I get no error and no effect :smiley:

That would also be my guess :slight_smile:

Is the Python node still returning null ? Or returning an empty list or something ?

My fault - I tried to place view already placed on sheet! BUT I then decided to place a schedule which can be placed on multiple sheets and still get the same message. Will try to create a specific new view to test it.

p.s.

It went fine with newly created view but I wonder why Schedule didn’t work.
