I'm trying to use a elevation raster to create a new routed stream line, but I can't believe how stuck I am. I went through Fill, Flow Direction, Flow Accumulation, and Con to get a raster the stream lines as the highest accumulations in my AOI. Then I used Raster to Polyline and got a polyline shapefile of the streams from which I selected the one stream line I want to analyze and made a new shapefile. But when I start an edit session, select the stream line, and try the Make Route tool, I get "No accptable target available. Make Route creates M aware polylines." Is my problem that I have a polyline not a line shapefile? I can't find a way to convert polylines to lines.
I'm just trying to create some pairs of stream measure and elevation to give to a colleague in a spreadsheet. I did it once with some routed lines I already had, but wanted to run it again on a stream line directly from the elevation raster.
a line file is a polyline file, perhaps the distinction being that you need a featureclass/shapefile which is segmented.

No, it's not that. I guess I don't need the Route Editing toolbar at all. I just need to run the Create Routes tool on my polyline feature. Then the Shape* attribute changes from Polyline to Polyline M and I can then add my event table.
Which tool exactly are you using (which toolbar is it on)? The Make Route Event Layer takes a route as input, but you only have a line. Have you tried Create Routes?
Darren may have a point, but have a look at the discussion here
How Stream to Feature works from
since you said you used Raster to Polyline
Thanks, I think Stream to Feature might have helped me, because Raster to Polyline gave me a stream line going the wrong direction which I didn't notice until after I added the elevations.
I've been at this so long that sometimes, no, often, I forget stuff I used to know. And sometimes I find something in Help that makes me think, "Hey, there's a new tool for this!" but it's an unrelated search hit, and sends me off the wrong direction. Thanks for pulling me back on track.
