Hello, so I was following this How To (How To: Convert slopes with a certain range of slope degree from a DEM file to a polygon feature class in ArcGIS Pro (esri.com)
which I had done a few times at this point since I was working with a number of different areas. When finishing the area, I was taking the slope and merging it into a single feature to clip it against another feature. When attempting to merge this later layer, I ran into the following error:
"Merge Features Failed. The spatial index grid size is invalid [Feature name]."
Thinking this could be resolved, I then recalculated the spatial index in the catalog menu, and tried again. Same error. I tried deleting the spatial index and trying again. Same error. I went out and tried to recalculate the spatial index through the geoprocess, which worked, but when I attempted a merge, I got the same error. I tried to use the tool: Recalculate Feature Class Extent, but I got a new error :
ERROR 160706: Cannot acquire a lock.
The file is in a File Geodatabase just like the previous attempts. The merge function works without errors in certain small areas of the project extent on the same file, it just can't be used on any meaningfully large section or in any predictable way for the smaller sections.
