[Question] Trying to change a phase in a viewport, but it is returning null

Revit
1

Hello all,

I am new to Dynamo and still learning the ins and outs. My goal with the following script is to

  1. Select a sheet
  2. Take the selected sheet and duplicate it.
  3. Take the one and only viewport on the sheet and directly change the phase on the viewport.

However, instead of returning true and working, I noticed it is returning null.

Any further suggestions? Thanks.

Not sure the best way to resolve this, but I’m noticing that Sheet.Viewports is returning viewport object, not a view. Getting the view itself might be a good place to start.

Looks like it is still returning null :pensive:

Open up the custom node returning a null value; At a minimum it should be returning a list of nulls, since it isn’t there is an indication you may have an environment issue (ie: not having IronPython2 installed).

Looked to be an environment issue. Thanks for your help!
