Loop through multiple input values ArcPy Toolbox

Nicola — Wed, 23 Jun 2021 12:51:20 GMT

Hello everybody,

I'm trying to create a tool in ArcGIS, that creates 3D Multipatches from multiple input values.

The tool should extrude between input TIN 1 and input TIN 2, then between input TIN 2 and input 3 and so on...

Somehow my loop is not working. It gives me three 3D Multipatches back, but 3 times the same.

Below I post my code. Maybe someone has an idea or a hint what is wrong with my loop.

# IMPORT MODULES import arcpy, os, sys, string, traceback # Input layers from typing import List, Any inLayers = arcpy.GetParameterAsText(0) inLayerslist = inLayers.split(";") # Output workspace outFolder = arcpy.GetParameterAsText(1) # OTHER FRONT STUFF for lyr in inLayerslist: n=len(inLayerslist) arcpy.AddMessage(str(inLayerslist)) arcpy.AddMessage(str(len(inLayerslist))) for i in range (0,n-1): arcpy.AddMessage(str(inLayerslist[i])) arcpy.AddMessage(str(i)) inPoly = arcpy.GetParameterAsText(2) layerName = lyr + "solid" + str(n) solid = arcpy.ExtrudeBetween_3d(inLayerslist[i],inLayerslist[i+1],inPoly,layerName)

Do you also need to extrude between the first TIN and the last TIN?

No.... Am I doing this 😅? I only need to extrude between the consecutive ones.

Hi Nicola,

Did you ever work out a solution to your Extrude Between script? I am facing a similar problem and am hoping to build off of any results you may have. Thanks for any help you can provide.

What about something like this?

inLayers = arcpy.GetParameterAsText(0) inLayerslist = inLayers.split(";") outFolder = arcpy.GetParameterAsText(1) inPoly = arcpy.GetParameterAsText(2) arcpy.AddMessage(inLayerslist) arcpy.AddMessage(len(inLayerslist)) for index, lyr in enumerate(inLayerslist): next_lyr = inLayerslist[index + 1] arcpy.AddMessage(f"Extrude between {lyr} and {next_lyr}") layerName = f"{lyr}solid{index}" solid = arcpy.ExtrudeBetween_3d(lyr, next_lyr, inPoly, layerName)
