Partial length or ratio of a poly line?

[GregRieck]

Hello,

If I have lines on my map and I use the graphic tools to draw a region that partially selects some of the line(s) in an area how do I determine the length of the line contained within the drawn region?

Use ITopologicalOperator.Intersect to the get the 1-D result then get the value of its Length property.
