Model builder strange behaviour in ArcGIS PRO

Hi,

I have 2 types of issue on modelbuilder in PRO.

1. I am unable to run model from geprocessing tool - it generates empty results. Model itself is set correct, because if it runs in edit mode/diagram view it works correctly - it gives correct results.

2. also i have find out, that model if runed normal as tool, does not add result to a map - same model if runed from a edit mode/ diagram view it adds result to a map display.

Can anyone explain this? it is a big pain in the **bleep** and very annoying to waste time on such thiigs.

Miha

Do you know at what step it fails?

I love model builder but I have found it to not always be reliable. For example, it loses setting for geoprocessing when I validate the model; therefore, it would not run correctly as a tool. Also I found field mapping sometimes gets dropped which doesn't provide expected results.

To solve this issue, I perfect the workflow in model builder than write it in python. Otherwise, I have to manually check some of the tools in model builder to make sure all parameters are filled out correctly and run it manually.

Good luck!
