Peter, What you can do is save a copy of your line as a different file. Open that file and place it in the map with your vegetation polygons Make the new layer (file) editable and "Objects>Set Target" Select all your Vegetation Boundaries and then "Objects>Split"
This will split your polyline up into the separate vegetation boundaries Create a new column in the new line table to store distance and % of total dist. Perform a "Table>Update Column" using the Expr: ObjectLen(Obj) for the fence distance in each vegetation polygon Find out the total distance by double clicking on the original line and use it for the Expr below Perform a "Table>Update Column" using the Expr: ObjectLen(Obj) / TotalDist for the fence percentage distance in each vegetation polygon I hope this is of help - Stephen Chan On Thu, 17 Mar 2005 17:01:35 +1000, Peter Hatton <[EMAIL PROTECTED]> wrote: > > Hi all, > can someone help me with the following > ............................. > I have a polyline ( > fenceline) that intersects a number of vegetation polygons of differing > vegetation types.
