Delete all fields from feature class with arcpy

Question

I want to delete all of the fields from a feature class in a simple tricky way, I don't want to loop over the fields because this method is very slow in arcpy.

I'm using a polygon feature class, I tried arcpy.MultipartToSinglepart_management but the feature class result saved all the fields.

Does anyone have any ideas?

I think you could do this with MakeFeatureLayer on your original feature class, using field_info to "hide" all the fields, followed by CopyFeatures to get the features with no fields in a new feature class.

UPDATE

Based on @geogeek's comment I investigated to make sure that this would work - and it did. Here are some Python snippets of doing the steps manually to get the syntax right.

arcpy.MakeFeatureLayer_management("C:/avhome/arcGISdata/Exploration.gdb/Samples","Samples_Layer","#","#","OBJECTID OBJECTID HIDDEN NONE;SHAPE SHAPE HIDDEN NONE;Dip_Angle Dip_Angle HIDDEN NONE;Strike Strike HIDDEN NONE;Rock Rock HIDDEN NONE;Description Description HIDDEN NONE")

arcpy.CopyFeatures_management("Samples_Layer","C:/avhome/arcGISdata/Exploration.gdb/SamplesNoAtts","#","0","0","0")

The only attributes on output are OBJECTID and SHAPE

You could work around it by creating a new feature class using the geometries of the old one but without the fields. The ArcGIS Resource Center has a section on working with geometry in Python. There' a section on reading and writing geometries that should cover what you need.
