Hi, I have roof data in shp format. I generated from airborne lidar. But they not come to one polygon as I added in pic. I want to make them 1 polygon. How can I merge all of them ? But some of them have gaps inside. I want to see them like the name of "source".

Do you want a 2D polygon enclosing the entire building or do you want a single object with the 3D roof structure?

Hi @bayram​ , ​since those polygons aren't coplanar, you cannot merge them to make a single 3D Polygon anyway, but you can aggregate them into a single MultiPolygon with Aggregator. 

Why not inspect features with Visual/Data Preview and Feature/Record Information before writing them into a destination dataset?
