Hello @s2439309g0f2 ,
I need to ensure we are talking about the same thing and request some further information.

You are working in Forma and using the extension environmental terrain analysis from the AppStore?
Could you please share a screenshot? I would also like to understand where the terrain edits are originating from, (are they done in Forma or is it a terrain you have imported?

Best,
Andrés

This message is typically displayed when the base terrain has not been altered. Forma requires at least one terrain modification before it can run the environmental terrain analysis. If your terrain is imported or untouched, the tool won’t calculate anything. Try making a small change to the terrain before repeating the analysis.
