Removing or Flattening Z and M values from a point Feature Class

I've had to flatten a Z value-laden point file before, or for whatever reason seen CAD data with M-awareness. For the life of me though I couldn't recall how the heck I did it in the past. It's like those tasks in GIS you do only once in a blue moon and cannot remember the name of the tool or what terms to search (see lattice dem).

Anyway, its actually a very simple process of exporting your data in ArcCatalog and just setting the environments.

from Esri:

Summary

Instructions provided describe how to create a copy of a feature class and disable M- and Z-value associations for the output feature class. These associations cannot be removed from an existing feature class.

M-values are routing values.

Z-values are elevation values.

Procedure

1. Browse to ArcToolbox > Conversion Tools > To Geodatabase.
2. Open the Feature Class to Geodatabase (multiple) tool.
3. Add all the feature classes into the Input Feature Class parameter.
4. Select an Output Geodatabase.
5. Click the Environments button at the bottom of the tool dialog box.
6. Expand the General Settings.
7. For the parameter, Output has Z Values, change the value to Disabled.
8. For the parameter, Output has M Values, change the value to Disabled.
9. Click OK in the Environments dialog box.
10. Click OK to execute the geoprocessing tool.
