Error Message when adding intrusion points to vein footwall model.jpg

Does anyone know why I'm getting an error message to the footwall of my vein model when I add points/vertices from an intrusion surface of another geological model? The error relates to having the same intrusion model/surface used for the boundary (lateral extent) of the vein model. Note that I can add the intrusion points/vertices when I don't use the intrusion surface for the vein model boundary.  Refer to screen capture of the error message.

    It sounds like Leapfrog is mad because you are giving it information that is in exactly the same location. Clipping operations that take part during constructive solid geometry operations are designed to cut things that fully cross-cut. When objects share exact boundaries, as it sounds like they might be doing in your example, the clipping operation fails. I'm extrapolating somewhat here, so maybe going in the wrong direction, but it sounds like you want your vein to run fully along the edge of your intrusion, like a rind. If so, I suggest you explore ways to pull the footwall 'through' the intrusion edge, maybe by creating inputs on the other side and turning off the boundary filter, or by trying a different avenue, like creating an offset surface from the intrusion to the what are currently the hangingwall points of your vein.

    Thanks, I understand what you mean. I'll create a separate surface so that there is this overlap you mentioned.

    Have a great day
