Add Z Information in ArcGIS Pro

Discussion created by mk4338 on Jun 22, 2020

I am using Add Z Information tool in ArcGIS Pro to calculate Z_Min and Z_Max from multipatch building data. The values in Z_Min starts from 400 m heights and the Z_max shows the height for example 415 m (which should be fine). My question is why the Z_min start from larger values approximately 400m?
