Convert a Multipatch feature into Line feature

DarrenLloyd__DOIT

My goal is to create feature lines by converting multipatch features. I'm using a application on my iPhone which captures indoor floorplan data as a GTLF file. I then use the ArcGIS Pro 3.4 Import 3D Objects tool to import the GTLF file and the output file type has the geometry type of 3D Object V2 (Multipatch). Is there a tool or series of tools to complete this conversion?

Yes, typically by converting the multipatch to a 2D footprint polygon, then converting that polygon to lines.

Run the Multipatch Footprint (3D Analyst Tools) | ArcGIS Pro documentation first then run the Polygon To Line (Data Management Tools) | ArcGIS Pro documentation second.
