I would like to set certain parameters for the View Range of specific views (ie Top Offset, Cut Plane, etc.). I know how to setup the views I want to collect and all that and I read through a post on retrieving the view range parameters but not setting them. Thus, I was wondering if anyone could help me figure out a way to set those parameters.
If using python, this is what I’d like to do:
import clr
Import RevitAPI
clr.AddReference(“RevitAPI”)
import Autodesk
from Autodesk.Revit.DB import *
Import ToDSType(bool) extension method
clr.AddReference(“RevitNodes”)
import Revit
clr.ImportExtensions(Revit.Elements)
#The inputs to this node will be stored as a list in the IN variable.
dataEnteringNode = IN
elements = []
for i in IN[0]:
elements.append(UnwrapElement(i))
for i in elements:
a=[]
a.append(elements[i].SetViewRange().SetOffset(PlanViewPlane.TopClipPlane))
#Assign your output to the OUT variable.
OUT = [a]
ERROR 1: I don’t know much about .SetViewRange() and if this is the way to go.
ERROR 2: I want to make it so I can run it with multiple views and not just once. Hence, the for loops ,however, this portion of the code:
for i in elements:
a=[]
a.append(elements[i].
does not work. Any ideas?
Hi @Dynamonkey
here are some elements that can help you :
in order to use SetViewRange, you first need to get the viewrange of the view (GetViewRange) and set some of its parameters . Here is a code that sets the parameters of the top clipping plane and the bottom clipping p
1. Import RevitAPI, TransactionManager and DocumentManager
import clr
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import*
clr.AddReference('RevitServices')
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
doc = DocumentManager.Instance.CurrentDBDocument
views = UnwrapElement(IN[0])
ltop = UnwrapElement(IN[1])
toffset = IN[2]
lbottom = UnwrapElement(IN[3])
boffset = IN[4]
count = 0
TransactionManager.Instance.EnsureInTransaction(doc)
for v,lt,tof,lb,bof in zip(views,ltop,toffset,lbottom,boffset):
2. Getting the viewrange of the view
viewrange = v.GetViewRange()
3. Setting the parameters of the viewrange
* Setting level of topclip plane
viewrange.SetLevelId(PlanViewPlane.TopClipPlane,lt.Id)
* setting offset of top clip plane
viewrange.SetOffset(PlanViewPlane.TopClipPlane,tof)
* Setting level of bottom clip plane
viewrange.SetLevelId(PlanViewPlane.BottomClipPlane,lb.Id)
* setting offset of bottom clip plane
viewrange.SetOffset(PlanViewPlane.BottomClipPlane,bof)
* Applying the viewrange to the view
v.SetViewRange(viewrange)
count = count +1
TransactionManager.Instance.TransactionTaskDone()
OUT = '%d view ranges altered' %(count)
you can set the level and offset for :
I gave inputs for plane levels and offsets but these can be determined from the viewplans themselves…

Here’s an easier to copy paste version of the code 
import clr
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import*
clr.AddReference('RevitServices')
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
doc = DocumentManager.Instance.CurrentDBDocument
views = UnwrapElement(IN[0])
ltop = UnwrapElement(IN[1])
toffset = IN[2]
lbottom = UnwrapElement(IN[3])
boffset = IN[4]
count = 0
TransactionManager.Instance.EnsureInTransaction(doc)
for v,lt,tof,lb,bof in zip(views,ltop,toffset,lbottom,boffset):
#getting the viewrange of the view
viewrange = v.GetViewRange()
#Setting top clip plane of the viewrange
# Setting level of topclip plane
viewrange.SetLevelId(PlanViewPlane.TopClipPlane,lt.Id)
# setting offset of top clip plane
viewrange.SetOffset(PlanViewPlane.TopClipPlane,tof)
#Setting bottom clip plane of the viewrange
# Setting level of bottom clip plane
viewrange.SetLevelId(PlanViewPlane.BottomClipPlane,lb.Id)
# setting offset of bottom clip plane
viewrange.SetOffset(PlanViewPlane.BottomClipPlane,bof)
#Applying the viewrange to the view
v.SetViewRange(viewrange)
count = count +1
TransactionManager.Instance.TransactionTaskDone()
OUT = '%d view ranges altered' %(count)

Thanks @Mostafa_El_Ayoubi this looks promising. I however cannot get it to run properly. To simplify I am only testing the top offset with 2 inputs.
IN[0] being a list of views and IN[1] being the top offset value which I’ve tried using a number slider, integer slider, string in all dimensional formats such as x’ x" but yet I get an error pointing to the for loop
for v,lt,tof,lb,bof in zip(views,ltop,toffset,lbottom,boffset):
which for this exercise I adjusted again only for top offset:
for v,tof in zip(views,toffset):
not sure if the for loop is the error but it points to that line and reads Typeerror: ___ not iterable
Perhaps there is a way to input the desired height offset properly.
Any thoughts?
If you want to use the same offset value for all view ranges , then you should only iterate through the list of views :
for v in views :
.
.
.
If you want a specific offset for each view than you must give the python node a list of offset values (same number of values as there are views)
Hello Mostafa,
I am trying to use your python script but there is a problem.
Any help would be really appreciated.
Since you’ve made a new post I’m going to close this (it’s over a year old anyway) and let the conversation continue there.
