Waiting for Sketchup.send_action to complete before continuing

I think using of Sketchup.send_action("view###:") is in some sense lazy approach to set appropriate view. I would suggest to use Camera class methods to set appropriate view and View class methods to zoom. It may require slightly more coding, but should run synchronously and sequence of commands may be united into one undoable single action.

@eneroth3

I concur!

Moving the camera yourself is also more future proof as the undocumented asynchronous behavior of send_action may change. Also it would require less code than using observers, and it would be much easier to understand how the code works if you one day several years into the future need to modify the plugin.

… I wasn’t yet convinced …

@DanRathbun

I don’t think you can get entirely away from using an observer.

… but I modified my example removed the observer, switched everything to camera manipulation and it works! I am now convinced, and stand conrrected.

[Code] Example: Saving Iso views to PNG image files

Continuing the discussion from Waiting for Sketchup.send_action to complete before continuing: I’ve actually modified my sample and removed the ViewObserver and got a working plugin. The strangest thing is that the user never sees any change in the viewpoint. It is like the write_image method is doing everything transparently in memory. If I didn’t check the directory for the written file, I’d think that nothing happened. And here is the working example with no ViewObserver … no dedicated …
