I am using the Grass plugin in QGIS for Windows (1.8.0). I am trying to split a polygon with a line feature. I am using the v.overlay.or function within the QGIS Grass plugin. I have the line layer as input vector map A, and the polygon as input vector B. When I run the function I get the following error:

 v.overlay ainput=cutlines@CompTest atype=line alayer=1 binput=buildings@CompTest btype=area blayer=1 output=bldg_overlay operator=or

 Operator 'or' is not supported for type line
 Finished with error

That is not related to the error I am getting. I have seen that post a while ago – Ryan Garnett May 08 '13 at 16:51
true, not related to the error but related to the problem you want to solve and might help others stumbling over this question. – underdark May 08 '13 at 17:21
From v.overlay's manual: or: also known as 'union' in GIS (only for atype=area). Not possible to use or with atype=area. – Nikos Alexandris May 17 '13 at 12:44
