Convert buffer polygons into polylines (using geometry of Street Centerlines)

EMH_Cbus — Fri, 06 May 2022 20:46:51 GMT

I am trying to use Street Centerlines polyline segments as the geometry to convert a polygon feature class into a polyline feature class, while also transferring over an single attribute field (named "PROJECTID", type Double).

Unfortunately, even when multiple line segments exist "Completely Within" a given polygon, they still will not Merge (I even cleared out the Field Map section).

I am also not sure what tool to use to transfer the attribute value for my "PROJECTID" field of the old polygon feature into the field for the new polyline feature.

Thoughts?

If I'm guessing correctly as to what you want, sounds like a spatial join on the two datasets will do it.

That will let you copy attributes from the polygons to a polyline layer that overlap them.

That seems to work, and I had to also use Dissolve instead of Merge since I am combining features within the same feature class, not multiple feature class files.

Select by Location: Centerlines "Completely Within" Project Selection
Spatial Join: Clines_dissolved (Target), Project_Selection (Join Feature), 1 to 1, "Completely Within"
Append: Cline_Proj_Added (Input), Polyline_Polylines (Target), "No_Test" (Schema)
