Boolean - Cut?

I search for something like the trueSpace boolean method create cut edge. With this method you create a edge where the faces of the two meshes crosses each other. Which is for example useful for creating a water border for a lake in a terrain.

I tried the Nvil Boolean method Cut with two intersecting cubes, and it does nothing. What exactly is the Boolean Cut in Nvil meant to do?

It depends on options set and pick order.

It appears to be working OK here.

Quick example for 2 cubes.

I pre-select object/mesh "A" before starting Boolean operation.
Start Boolean.

Mesh A will be cut by Mesh B, I have set the cut option to "Split" (which will split the object into 2 mesh)

Select Mesh A from the drop down box (for mesh A)


Pick Mesh B gives me the original object/mesh A split into 2 mesh


I can select one of the 2 mesh and move as needed

Okay, so i was in the right corner. Just the order of selection was wrong. Thanks Steve
