Hi everyone,
I am trying to make a selector that allows user to select levels/edges/faces for height dimensioning but i cant seem to get the selector to work for wall faces perpendicular to the view
# Import Revit and pyRevit modules
from pyrevit import revit, DB, UI
from pyrevit import script
# Get the current document
doc = revit.doc
uidoc = revit.uidoc
# Check if the active view is a section view
active_view = doc.ActiveView
if not isinstance(active_view, DB.ViewSection):
script.exit("This script only works in section views.")
# Create a custom selection filter for all faces, edges, and element lines
class AllFacesAndEdgesSelectionFilter(UI.Selection.ISelectionFilter):
def AllowElement(self, elem):
# Allow all elements that are not hidden in the active view
if elem.IsHidden(active_view):
return False
return # Allow all visible elements
def AllowReference(self, reference, point):
# Allow all geometric references like faces, edges, etc., even if perpendicular
reference_types = [
DB.ElementReferenceType.REFERENCE_TYPE_NONE,
DB.ElementReferenceType.REFERENCE_TYPE_LINEAR,
DB.ElementReferenceType.REFERENCE_TYPE_SURFACE,
DB.ElementReferenceType.REFERENCE_TYPE_FOREIGN,
DB.ElementReferenceType.REFERENCE_TYPE_INSTANCE,
DB.ElementReferenceType.REFERENCE_TYPE_CUT_EDGE,
DB.ElementReferenceType.REFERENCE_TYPE_MESH
]
if reference.ElementReferenceType in reference_types:
return True
return False
# Prompt the user to select any visible elements or faces
selection_message = "Select visible edges, faces, or lines in the view."
# Allow the user to select multiple geometry elements using the custom filter
try:
all_faces_filter = AllFacesAndEdgesSelectionFilter()
references = uidoc.Selection.PickObjects(
UI.Selection.ObjectType.Element, all_faces_filter, selection_message)
if not references:
script.exit("No geometry was selected.")
# Extract selected elements and display their information
selected_elements = []
for ref in references:
element = doc.GetElement(ref.ElementId)
selected_elements.append(element)
# Output the selected elements' information
output = script.get_output()
output.print_table(
table_data=[(element.Id, str(element)) for element in selected_elements],
title="Selected Elements",
columns=["Element ID", "Element Details"]
)
except Exception as e:
script.exit("Selection canceled or error occurred: {}".format(e))
I tried using the ISelectionfilter but i can only select elements this way, not edges/faces etc
On my phone but it should look like
faces = uidoc.Selection.PickObjects(ObjectType.Face, "Select faces"
Have a look at pyrevit code, it usually contains snippets that get you going
