I'm trying to apply a Base Height extrusion that's 10 feet in height to all layers in my ArcGIS Pro map document using a python script. Per ESRI's documentation on extrusion, the syntax should be extrusion ({extrusion_type}, {expression}) .

Below is the code that I'm trying to use. It's not that graceful as I'm still trying to learn python:

import arcpy

# Variables to form defintion query
field = 'SUBCODE'
value = "(1152,1153,1154,1155)"

# concatenate query syntax
queryStr = str(field) + '"IN"' + str(value)

# Specify the aprx project (CURRENT), dataframe (Layers)
p = arcpy.mp.ArcGISProject("CURRENT")
m = p.listMaps("Map_3D")[0]

# Apply defintion query to specified layer group
for lyr in m.listLayers("CONDO*"):
if lyr.supports("DEFINITIONQUERY"):
   lyr.definitionQuery = queryStr

# Make copy of selected features

# Layer 3D To FeatureClass

# Apply extrusion
for lyr in m.listLayers("CONDO*"):
if lyr.supports("EXTRUSION"):

I'm not receiving any error when I run the script nor is it making updates to the layers.

  • Can you expand your code snippet so we can see more of what you've defined above for lyr in m.listLayers()? What/where is m? – Midavalo Nov 14 '17 at 0:01
  • Thanks Midavalo for your reply. I've made edits to my original question so that you can see the entire code. – pac_co Nov 14 '17 at 14:12
  • I figured it out - I forgot to apply the Geoprocessing tool "Layer 3D To Feature Class". Thanks again for reaching out to help Midavalo! – pac_co Nov 14 '17 at 14:37

I needed to use the Geoprocessing tool "Layer 3D To Feature Class" in order to have the extrusion work. Here's a copy of the syntax I used:

 arcpy.Layer3DToFeatureClass_3d(input, output)
  • updated my code to show where I applied the "Layer 3D To Feature Class" – pac_co Nov 14 '17 at 15:44
