I created a model using ModelBuilder in ArcGIS Pro to make a LAS ground only layer from LAS files. I first created LAS dataset using LAS files and then used make las dataset layer option. I am able to apply surface constraint to the main LAS dataset but the issue is that surface constraint is not applied in final LAS layer.

I have attached screenshot of my model and the issue faced.

The short version of my problem is The model is not able to select surface constraint automatically.

LAS Model Surface constraint
