I buffer ditches as part of my work (to represent potential removal of wetland hydrology). This is an interesting concept. Would love to see more options for buffer end types as well.

How about allowing this via a GP Tool/Python. (Yes, I know of and much dislike 'field map') I bet most folks want to do it via script and not manually. Glad it's added to 10.1, have already used it.

Thanks...struggled with this one for a while before I found your post. Pulling a number from a text column required extra single quote around the number.

I am not familiar with working with Shape field and was trying to write this on my own. Big thanks to Gasior, exactly what I needed. I believe the result is same as IanKo's Get Average Z tool, which is not rewritten for 10. I like it better in Python anyway. Dave

Bump, Again. Think I have a work around but would still like to see this functionality as a direct field calculation. I believe Linear Directional Mean (Spatial Statistics Toolbox) will work for my purposes. Just wanted to share, hate to hijack the suggestions box. The tool is intended to calculate the mean direction of multiple lines; however there is a Case Field option that will compute the 'Compass' angle for each feature. If you use a unique ID field as the Case Field, angle is calculated for each respective feature. Then it's just a cursor or join/calculate operation to populate the original FC with the output FC from Linear Directional Mean. Use with caution: there are nuiances between spatial reference files and other variables that may generate inaccurate angle values. My results match Easy Calculates resutls sometimes, sometimes they are off by as much as a degree. This may/may not fit a given need; in my case it's acceptable error. Hope this is helpful to someone.

Bump. Not sure if Ian Ko will provide this with Easy Calculate 10. He is definitely saying it won't be available for 10.1. Bummer his stuff is great. I've tried to reproduce this calculation in Python with no success. Am not familiar with VBA so it it tough to translate to python. Agree with the user below, any ESRI Solution should handle multi-vertex lines not just simple 2 vertex lines.

I am trying to reuse the output .txt parameter file from Topo To Raster in Topo To Raster By File. This txt was generated by the GP Tool itself. Problem is: When I attempt to use this txt as the input parameter file for 'Topo To Raster By File' I get the following error: ERROR 010134: Input does not contain a feature class. That's the extent of the error message, so I've turned to the forums. I'm at 9.3.1. Here is an example of the input txt file: POINT C:\Data\DEM\Test11.gdb\PntFC3720452300WC20050817 Z POINT C:\Data\DEM\Test11.gdb\PntFC3720452400WC20050817 Z POINT C:\Data\DEM\Test11.gdb\PntFC3720453300WC20050817 Z POINT C:\Data\DEM\Test11.gdb\PntFC3720453400WC20050817 Z ENFORCE ON DATATYPE CONTOUR ITERATIONS 40 ROUGHNESS_PENALTY 0.25000000000 DISCRETE_ERROR_FACTOR 1.00000000000 VERTICAL_STANDARD_ERROR 0.25000000000 TOLERANCES 2.50000000000 100.00000000000 CELL_SIZE 20.00000000000 MARGIN 20 Any help on this issue? Have a feeling it's the auto-generated syntax in the txt file. Have no issue running the Topo To Raster tool, but I'm working to create this with Python as part of a bigger routine and this is causing severe delay. Ironically the help on these two tools says using this txt input parameter file is supposed to be 'easier'... Before I start in on that... is (are) my FC name(s) too long? Will be checking while awaiting replies. Thanks, DJ
