Solid-polyline,exstrude, cap hole

im going to export a solid joint from GH to abaqus. And I wonder if a make a joint in GH by polyline between points, than exstrude the polyline in one direction (normal to the point plane), and make use cap holes. Does that mean that the model than is a solid inside the “red” area? (The screenshot wont upload…)
Thanks!:slight_smile:
