Loop through and ViewCaptureToFile on 'Named Views' Panel

Jack_Zeng · November 24, 2018, 3:37pm

Hi all,
I want to loop through all the saved views on ‘Named Views’ panel. But I am not sure how to achieve it.

I know you can return the view names by using ‘rs.NamedViews()’. But I cannot find the command to set current view using view names. ‘rs.CurrentViews’ doesn’t seen like what I am looking for…

The last step would be ask python to do ViewCaptureToFile. I wonder how to predefined the file name and location so I don’t need to mannually do it for every view.

Appreciate for any suggestion.

Thanks,

Maybe have a look at this sample:

Thanks Nathan. Instead using VBScript, is that possible to resolve it via a few python lines? I think there must be some easier way. What I missing is the command to active the view/camera and the command to do an automatic ‘ViewCaptureToFile’ without any popup menu. I tried using rs.command("_ViewCaptureToFile") but don’t how to predefine all parameters like location, dpi, file name etc.
Thanks

Here a sample code to get/set active view

github.com

mcneel/rhino-developer-samples/blob/6/rhinocommon/snippets/py/get-and-set-the-active-view.py

from Rhino import *
from Rhino.Commands import *
from Rhino.Input import *
from Rhino.Input.Custom import *
from scriptcontext import doc

def RunCommand():
  # view and view names
  active_view_name = doc.Views.ActiveView.ActiveViewport.Name

  non_active_views = [(view.ActiveViewport.Name, view) for view in doc.Views
                      if view.ActiveViewport.Name <> active_view_name]

  # get name of view to set active
  gs = GetString()
  gs.SetCommandPrompt("Name of view to set active")
  gs.AcceptNothing(True)
  gs.SetDefaultString(active_view_name)
  for view_name, _ in non_active_views:
    gs.AddOption(view_name)
