Currently the Intersect3DLineWithSurface tool does not output the point_feature_class when the End or Start Nodes of the input 3D line features touch the surface. When I use the analysis.Intersect and ddd.Intersect3DLines tool with two 3D polylines features, I can obtain the output points where the End or Start Node of the 3D polylines touch the 3D polylines. It would be nice for Intersect3DLineWithSurface tool to output the point_feature_class when the input 3D line features touch the surface at the End or Start Nodes. ... View more

Output Lines is now the output of the Intersect 3D Line with Surface Tool, with Output Points being optional. It would be beneficial to make both Output Lines and Output Points optional. In the process of generating a photo footprint polygon utilizing the Intersect 3D Line with Surface Tool, specifically from an EO file and a DEM, the production of Output Lines is not required. ...

It appears that the arcpy.env.XYTolerance and arcpy.env.XYResolution settings do not influence the arcpy.3d.ExtractLas tool. Irrespective of the values assigned to these parameters, the outcomes remain consistent, suggesting that the default values (arcpy.env.XYTolerance = 0.001 and arcpy.env.XYResolution = 0.0001) are being utilized. Therefore, it would be beneficial to enable the integration of arcpy.env.tolerance and arcpy.env.resolution settings within the ExtractLas Tool to enhance its versatility. In my recent ExtractLas process, I identified that some las points are outside the designated Extraction Boundary (Optional). However, this issue wasn't present when using the Clip Tool with the same arcpy.env.XYTolerance and arcpy.env.XYResolution settings.   ... View more

I am using the Tile LAS (3D Analyst) tool to create tiled las files from a las dataset. The tiling options are set to 'Import from Feature Class,' and both the input Feature Class and the LAS dataset use a geographic coordinate system. Here is the error message: ERROR 999999: Something unexpected caused the tool to fail. Contact Esri Technical Support (http://esriurl.com/support) to Report a Bug, and refer to the error help for potential solutions or workarounds. The specified index is out of range. Failed to execute (TileLas).

Does this mean it is also compatible with a geographic coordinate system? Your expert advice is highly appreciated. Thank you.     ... View more

Currently "The NoData cells will not be transformed into points" by Raster to Point  tool. It would be nice to add {NODATA} option to Raster to Point tool to export NODATA as -9999, similar to the Raster to ASCII tool. ... View more

The Summary of Create Fishnet (Data Management) tool states: Creates a fishnet of rectangular cells. The output can be polyline or polygon features. Please add label to {geometry_type} option of this tool , then the output can be polyline, polygon or label features. Currently, setting the {labels} option to 'LABELS' creates a point feature class, but {geometry_type} must also be set to 'polyline' or 'polygon' to output those geometries with labels. Introducing a 'label-only' option could improve tool performance by generating only the labels when they are needed. ... View more

Using a single map sheet to clip a LAS dataset with multiple las files via the ExtractLas tool currently results in multiple output las files if the map sheet covers multiple las footprints. Adding a {Merge_las} option to the ExtractLas tool would streamline this process by consolidating the outputs into a single LAS file. ... View more

It would be beneficial to add a {Connect_to_Centroid} option to the Collapse Hydro Polygon tool. This would create straight and simple centerlines for road polygon intersections. Here is an example: Blue labels represent the Centroids of these intersections. This tool accurately identifies the center of each shared adjacent road Arcs. Connecting these center's Start or End Node to the centroids of road intersections would yield improved centerlines. The Summary of the Collapse Hydro Polygon tool states: "Collapses or partially collapses hydro polygons to a centerline based on a collapse width."  I'm curious why this tool isn't named Collapses Polygons to Centerlines or just Polygon To Centerline, especially since it works for both hydro and road polygons!  ...
