Create Brep from two offset surfaces

Hi, I’m trying to create a brep out of two surfaces that have been created through a grasshopper script. These two surfaces have been offset from each other and I cant find a way to connect them together to create a solid piece of geometry. I need to join these two surfaces so that I can use the ‘Solid Difference’ tool to create a hole between the intersection of two breps.

Hi Tom,
There might be an easier way, but I would just deconstruct each surface and create ruled surfaces between the edges. Then if you join everything it should form a closed brep you can boolean.

Hello
you can offset the curve


Connect the 2 ends then cap

Or deconstruct loft and offset, the loft edges, then join

Most of what I did is in the white group. (Nice spiral.)
