Idea: generate lines from faces-turn lines into faces-get the attributes of faces.
(1) features to lines, and lines are generated from polygons.
Data management tool function to line.
(2)featureto polygon converts the line into new_polygon.
(3) spatial connection spatial connection attribute
To maintain the attributes of the original polygon, use feature turning points to convert the original polygon feature class into points, and then use spatial connection to connect with new_polygon spatially, or use the label feature option to hook the points generated by the original polygon when converting the previous lines into polygons.
2. Tool Delete Unique
2. 1 Calculate the surface centroid
coordinate
Add two fields to record the x and y coordinates of the centroid respectively, and use CalculateGeometry to calculate the x coordinates and y coordinates of the centroid.
2.2 Delete duplicate faces by deleting the same ones.
Look at the X and Y coordinate fields of the centroid calculated in 2. 1 in the tool interface, and the tool will compare the elements with the same attribute value and delete them.
