How can I erase a "line feature" (erase feature) from a "polygone feature" (input) in ArcGIS 10?

With the tool "erase" I can only use an other "polygon feature" as erase feature for a polygon (input).But I can not use an "line feature" as erase feature for a polygon.

I there an other tool in ArcGIS or an other way to solve this problem?

    ? And what is the expected result? Two polygons separated by the line? – GISGe Feb 11 '14 at 12:17
  • It should be one polygone with a gap in shape of the line. So the line should have some width but then it is not a line anymore but a polygon? So how can a create a polygon of defined width from line feature? If I could create such polygon feature I could use the "erase" Tool to create the gaps. – user26815 Feb 11 '14 at 13:03
  • The Buffer Tool will create a Polygon from a Line, at a specified width. – klewis Feb 11 '14 at 13:10
  • A line feature has no area. You can either split a polygon with a line feature, or, as you have now suggested, buffer the line feature by a certain width to create a new polygon, and then erase it from your original polygon feature. – HDunn Feb 11 '14 at 13:10
  • or you convert your polygon to line and erase the line. – radouxju Feb 11 '14 at 13:11
