Perspective eye and target coordinate extraction

Does anyone know how to extract coordinates for a perspective view target/eye?

Rotate 3D Views from dynamo

Hi All, I’ve been trying to find a way of modifying the orientation of a 3D view from Dynamo but couldn’t how. is there a way to access that command from dynamo? Thanks,

View Orientation and Python Script refresh

The Python script below is one I’m using to capture the view orientation of one 3D view and set the view orientation of a list of views to match the captured one. It works perfectly…the first time. On subsequent runs after the first view is changed, the list of views do not update themselves. This does not appear to have anything to do with the Unlock and Save/Lock, as removal of those lines does not improve the behavior at all. At this point, my remedy is to disconnect one of the script inp…

Thank you both. I am having trouble running the script (something about “unlock” not being recognizable syntax).
That said, I thought that there may be a way to extract XYZ coords for eye and target points for perspectives without going into the API. Is that not the case?

Where does this assumption come from? Do you have any reference to share?

[Alejandro_Ogata1]

Well… this is probably an unfounded assumption. But there is a dynamo node (PerspectiveView,ByEyePointAndTarget) that creates a perspective view by inputting a 3d point for “eyePoint” and one for “target”. So, my guess is that the information of those 2 points may be stored somewhere. Something akin to line.EndPoint and line.StartPoint

Take a look at [&] View.SetPerspectiveCamera (Ampersand) or at PerspectiveView.OrientToEyeAndTargetPosition (Clockwork) and at the scripts inside maybe…

[Alejandro_Ogata1]

thanks. I’ll take a look. Though now I’ve found that it is tricky to get the camera’s focal length as an output.

Additionally, there is a new class for the camera in Revit 2018:
