BUG-000173708
Exploratory 3D-Analysis Interactive Cut and Fill Tool does not calculate volume or area values if the Display adapter is set to DirectX 12 in ArcGIS Pro 3.4
(Fixed in Pro 3.5. Thanks!)
support's workaround is to change from DirectX 12 to DirectX 11
When is Pro 3.5 going to be released?
(I know, UC-ish, But, The 3rd Full Moon Before The UC Sounds Good To Me)
DirectX 12 shows all zeros in the analysis graphic
