Hi Anthony Von Moos ,
There are a couple of tools out there that will split your line using different methods inside and outside editing sessions, but I don't think it will update your bmp and emp values. See the support page on this topic:
You can script this using the segmentAlongLine function in arcpy. Below an example of the logic:
import arcpy
split_dist = 2.5
fpnt = arcpy.Point(0, 0)
tpnt = arcpy.Point(10.5, 0)
sr = arcpy.SpatialReference(102100)
line = arcpy.Polyline(arcpy.Array([fpnt, tpnt]), sr)
dist = 0
endprev = 0
cnt = 0
while dist <= line.length:
cnt += 1
bmp = endprev
linep = line.segmentAlongLine(dist, dist + split_dist, False)
emp = dist + linep.length
print("line {}".format(cnt))
print(" - bmp {}".format(bmp))
print(" - emp {}".format(emp))
endprev = emp
dist += split_dist
This will print:
line 1
- bmp 0
- emp 2.5
line 2
- bmp 2.5
- emp 5.0
line 3
- bmp 5.0
- emp 7.5
line 4
- bmp 7.5
- emp 10.0
line 5
- bmp 10.0
- emp 10.5
