I have a template file from which I am retrieving tolerance and resolution settings as in the code below. Using arcpy.AddMessage, I am able to confirm that the settings were retrieved from the template file and applied. I then run FeatureClassToFeatureClass in a bid to have the newly set tolerance and resolution values applied to the output feature class. Unfortunately, these settings are not applied to the output file. When I run this same code in the python window, the settings are applied as expected. I am using ArcGIS Pro 2.5.1. Dan Patterson templateFile = arcpy . GetParameterAsText ( 0 ) if templateFile != "" : sr_object = arcpy . Describe ( templateFile ) . spatialreference arcpy . env . MTolerance = sr_object . MTolerance arcpy . env . MResolution = sr_object . MResolution arcpy . env . XYTolerance = "{0} {1}" . format ( sr_object . XYTolerance , sr_object . linearUnitName ) arcpy . env . XYResolution = "{0} {1}" . format ( sr_object . XYResolution , sr_object . linearUnitName ) arcpy . AddMessage ( arcpy . env . MTolerance ) arcpy . AddMessage ( arcpy . env . MResolution ) arcpy . AddMessage ( arcpy . env . XYTolerance ) arcpy . AddMessage ( arcpy . env . XYResolution ) arcpy . FeatureClassToFeatureClass_conversion ( "Mylayer" , "//Path//to//gdb" , "OutLayer" )

I also tried running it with the code below to ensure that the linear units show up as feet instead of foot. templateFile = arcpy . GetParameterAsText ( 0 ) if templateFile != "" : sr_object = arcpy . Describe ( templateFile ) . spatialreference units = "" if sr_object . linearUnitCode == 9002 : units = "Feet" else : units = sr_object . linearUnitName arcpy . env . MTolerance = sr_object .

AddMessage ( arcpy . env . XYTolerance ) arcpy . AddMessage ( arcpy . env . XYResolution ) arcpy . FeatureClassToFeatureClass_conversion ( "Mylayer" , "//Path//to//gdb" , "OutLayer" ) The AddMessage results then were: 6.213699494949262e-07 6.213699494949262e-08 0.003280839895013 Feet 0.0010763910416709318 Feet This didn't make a difference in the behaviour of the script. It's still pretty erratic. It doesn't work 99% of the time and then it will randomly work out of the blue with no changes to the code.

No. I am writing to a geodatabase in ArcGIS Pro.

DavidPike

Are you writing to a feature dataset? I guess that would ignore any environments to preserve topology etc?

I also tried running it with the code below to ensure that the linear units show up as feet instead of foot.

Here are the AddMessage results:

6.213699494949262e-07
6.213699494949262e-08
0.003280839895013 Foot

But when I look at the properties of the output, it has different values from above.

DavidPike

can you humour me and show the print/add message results please

MarvisKisakye1

I tried setting the environments as you did above but they are still not applied to the output files.

DavidPike

I know it makes little sense but it may be an arcpy quirk, have you tried something like:

MTolerance = sr_object.MTolerance

arcpy.env.MTolerance = MTolerance

…

arcpy.FeatureClassToFeatureClass_conversion()
