i need help model builder to duplicate feature parallel with specified distance
i have a script in arcpy but i can not run coz i did not understand the code :
import arcpy, math
infc=r'..\SCRARCH\clone.shp'
def CopyParallel(plyP,sLength):
part=plyP.getPart(0)
lArray=arcpy.Array();rArray=arcpy.Array()
for ptX in part:
dL=plyP.measureOnLine(ptX)
ptX0=plyP.positionAlongLine (dL-0.01).firstPoint
ptX1=plyP.positionAlongLine (dL+0.01).firstPoint
dX=float(ptX1.X)-float(ptX0.X)
dY=float(ptX1.Y)-float(ptX0.Y)
lenV=math.hypot(dX,dY)
sX=-dY*sLength/lenV;sY=dX*sLength/lenV
leftP=arcpy.Point(ptX.X+sX,ptX.Y+sY)
lArray.add(leftP)
rightP=arcpy.Point(ptX.X-sX, ptX.Y-sY)
rArray.add(rightP)
array = arcpy.Array([lArray, rArray])
section=arcpy.Polyline(array)
return section
with arcpy.da.UpdateCursor(infc,("Shape@","Width")) as cursor:
for shp,w in cursor:
twoLines=CopyParallel(shp,w)
cursor.updateRow((twoLines,w))
