Creating a python toolbox using the ESRI .pyt format. This tool is very straight forward (at least in theory) in that one polygon input generates three outputs: a convex hull layer for the input polys, a centroid layer for the input polys, and an intersection of the convex hull and centroids.
def execute(self, parameters, messages):
"""Execute linear orientation analysis."""
input = parameters[0].valueAsText
baseName = arcpy.Describe(input).baseName
arcpy.env.workspace = arcpy.Describe(input).catalogPath
#overwrite doesn't work, tool still fails if output already exists
arcpy.env.overwriteOutput = True
#output names
mbg = "{0}_MBG".format(baseName)
cents = "{0}_centroids".format(baseName)
intersectOutput = "{0}_MBG_Intersect".format(baseName)
#output
arcpy.MinimumBoundingGeometry_management(input,
mbg,
"CONVEX_HULL",
"NONE", "#",
"MBG_FIELDS")
arcpy.FeatureToPoint_management(input,
cents,
"INSIDE")
arcpy.Intersect_analysis(in_features = [mbg, cents],
out_feature_class = intersectOutput,
join_attributes = "ALL",
cluster_tolerance = "-1 Unknown",
output_type="INPUT")
returnStack trace on the error seems to indicate that arcpy.Intersect_Analysis cannot find the feature classes generated by MinimumBoundingGeometry and FeatureToPoint that the script just created:
Traceback (most recent call last):
File "<string>", line 111, in execute

Failed to execute (Intersect).
Commenting out lines 26-30 produces viable output from the MBG and F2P tools.
Anybody run into this one before? Am I missing something obvious - perhaps scoping issues - inherent to .pyc toolboxes/classes, or this is another instance of arcpy $#!^ing the bed?
