Thin Indoor Pathways failed to execute (CalculateField)

MappyIan

Having successfully created PrelimPathways and PreliminTransitions I'm trying to run the Thin Indoor Pathways tool but it keeps failing with the following error:

ERROR 000539: Invalid field PrelimTransitions.LEVEL_ID

The final section of the message stack is as follows:

The PrelimTransitions attribute table doesn't have a LEVEL_ID field and I've not modified the table structure at all so its never had that field. I'm at a loss to know why it's failing.

I'm using ArcGIS Pro 3.0.2

Any help would be greatly appreciated!

Hi Ian! Sorry you're experiencing this; thank you for sharing the screenshots and the version of Pro -- very helpful!

At ArcGIS Pro 3.0 the schema for the Pathways and PrelimPathways feature classes were enhanced to include a LEVEL_ID field, to support floor filtering of pathway features in maps and scenes. If the Indoors network datasets were created using a previous version of ArcGIS Pro, the LEVEL_ID field will be missing, but can be added manually following the instructions found here.

Hope this info helps!

Hi @MarkusBellinghoff, sorry for the belated reply. I'm curious if you modified your transitions prior to running Thin Indoor Pathways (say, to create a landing between floors or similar)? If so, and additional vertices now exist between levels, it would cause this error at Pro 3.0. The workaround if you've already created your transitions features is to re-create transitions features but don't modify them to create inter-level features yet (you could copy the existing ones to a scratch feature class to preserve them if necessary) and run Thin Indoor Pathways. Then make updates as necessary, such as creating your landings between levels.

Hi @JasonHineEsri! I am getting the same error message as Ian, but a LEVEL_ID field is already present in my PrelimPathways.

I'm a little confused because the error message refers to an invalid LEVEL_ID field in PrelimTransitions (not PrelimPathways). Here I wouldn't know how to populate such a field because the transitions refer to multiple levels.

I am using ArcGIS Pro 3.0.1.

Any hints would be very appreciated.

Hi @JasonHineEsri, many thanks for the prompt reply. I re-created the PrelimPathways layer and then ran 'Thin Indoor Pathways' and it completed without error.
