I am adding parking spaces into a parking lot, and I need them to be exactly the same shape and not overlap each other or have spaces between. In ArcMap 9.3, there was an editing task that allowed you to split a long rectangle into multiple, equal-width polygons. I am having trouble finding this tool in ArcMap 10. Does anyone know how to do this?
The Parcel Editor Toolbar offers this functionality, free with Arc 10. You need an Editor or ArcInfo license. Select a feature with the Select Parcel Feature tool, right-click Parcel Division. You can divide by Equal Area or Equal Width.
Please see the ESRI online help (parcel division).

Off the top of my head, I don't know of anything in 9.3 that does what you're describing. It does look like 10 has a tool to do this when you're working with parcel fabrics: Creating new parcels using divide by area.
