Repeating unit name in indoors

Question

Hi,

I am working on ArcGIS Indoors and was creating a floor aware map. I noticed that some unit name is assigned to multiple units and also their Unit ID is same. I have attached an image in which L1E145 unit is coming three times why am i facing this behavior, similarly for unit L1E175.

Why is this happening i have followed the steps of the arcgis indoors tutorial provided by ESRI, is this an issue of the CAD file?

Hi @AbhyanshuGupta --

You're essentially correct that this result is due to the CAD data. This result is happening because of differences in the way CAD and GIS denote polygon "holes". It is not uncommon for ArcGIS Pro to read concentric closed shapes in the CAD as overlapping polygons. After import, it's important to check for these and other potential data quality issues that may be the result of conditions in the CAD data.

If you're following the Load Data to the ArcGIS Indoors Information Model tutorial, steps to resolve this data quality issue post-import are described starting on page 8 of the PDF. To learn how CAD data can be prepared to help avoid this happening during import, see this bullet of the Prepare CAD for ArcGIS Indoors help topic.
