Rotate 3d isometric View

Hello everyone! Is there any way to rotate an existing 3d isometric view?. I have found the means to modify perspective views, but it doesn’t suit me.

It seems like the solution lies somewhere in DesignScript language or in Python. But i couldn’t find any specifications with system functions to set values in (view3d.orientation. etc.), either i noticed, sometimes people are using such functions in code blocks and it works.

Here i found some API, but i don’t understand how to translate it to Dynamo languages.

It seems to be a solution, but what if I need my view to be set by specified vector? For instance, if i’ve got a set of coordinates (i am not fluent in Python :upside_down_face:)

This should be very useful for creation animations. Thanks for any help :smiley:

Hey,

So, we can change a 3D view by vector like this… (thanks to RIE)

I suspect that you want more control, in which case you need 3 things… An origin, a direction to look and an Up direction…

Unfortunately we can’t extract a ‘target’ from a 3D view, I don’t think… we can’t find the ‘centre’.

So if we change the direction, we will look at something else… which isn’t what you want…

For an animation, that might not be a problem, you would naturally get a location point, create your Eye, Look Direction and Up, then use the location point to create new Eye and Directions…

clr.AddReference("RevitNodes")

clr.ImportExtensions(Revit.Elements)
clr.ImportExtensions(Revit.GeometryConversion)

clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument

#we need to unwrap Dynamo 'elements'
view = UnwrapElement(IN[0])
#we need to convert Dynamo Vectors & Points to Revit XYZs
forward = IN[1].ToRevitType()
eye = IN[2].ToRevitType()
up = IN[3].ToRevitType()

#start transaction
TransactionManager.Instance.EnsureInTransaction(doc)
#unlock view
view.Unlock()
#get up direction
#up = view.GetOrientation().UpDirection
#create a new orientation object based on our modified info
viewOrientation = ViewOrientation3D(eye, up, forward)
view.SetOrientation(viewOrientation)
#finish transaction
TransactionManager.Instance.TransactionTaskDone()

OUT = view

Hope that helps,

Woooooooooow this is great, thank you! maybe you’ve got some specification with all commands and systm functions?

Umm… there’s a few places… Maybe these are useful?
