Remove M and Z values using ArcObject??

SongWendong — Fri, 12 Jul 2013 02:20:25 GMT

Is there a way to remove M and Z values from featureclass using ArcObject?

I know I can do it with python to export the featureclass to another gdb by disable M and Z values in enviroments settings.

I just want to know is there a better way to do it without exporting data, and I want to do it using C# and ArcObject.

I cannot find the right interface.

Any helps?

If your source dataset has ZM values (even if they are not set) and you want to drop these from the entire dataset you will have to export the dataset to a new FeatureClass which does not support ZM values. If you want to achieve this in ArcObjects the easiest way is probably to call the geo-processing tool using the execute method on the IGeoProcessor object.

In ArcObject, there are IZAware and IMAware interfaces, you can call DropZs and DropMs to reset the Z values and M values, or set ZAware or MAware properties to false. These do not apply to feature class, so you have to go through each feature and get the geometry.
