A geometric design with many points and lines! This design seems to represent a collection of curved surfaces or sections, likely representing parts of a ship or submarine hulls. The "walls" referred to in the instructions would likely be part of this overall structure. Given your specification of an input and expected output for an algorithm like Netfabb’s 3D Printer, you probably want something like: ``` wall_thickness = 1.6 outer_surface_meshes.append(sharpie.create_outer_surface_mesh(preview_design.points_with_normals())) inner_hull_surface_meshes.append(sharpie.create_inner_hull_surface_mesh(preview_design.surface_elements())) surface_shrink_factor=0.95, inner_hull_mesh_inflate_amount=4 output_settings.update( sharpie.export_settings('FMMeshObjectFormat3d')) preview_mesh_objects = [] outer_preview_surface = outer_surface_meshes[0].create_copy(apply_degenerate_vertices=True) ``` This would result in exporting the object as a 3D printer model. Please note this example code uses specific methods and class instances, which are likely part of an overall tool suite that provides this functionally (Netfabb). The provided instructions would probably translate directly into such an operation for an existing software solution. However, translating them precisely is outside my ability since it requires direct reference to the internal logic of this suite, specifically its implementation and the specifics regarding how the export function would need to be configured based on given instructions and settings within that system. However, using similar structure: ```python outer_surface_meshes = [ # mesh created by preview_design surface elements as described before] ] for inner_hull_mesh in sharpie.export_surface(0.9, [preview_design], outer_preview_surface): for outer_mesh_object, output_setting, filename_string_list, save_as_file_list, layer_height_setter_method, filename_prefix in preview_mesh_objects: ``` Assuming we only work on single meshes and without a need for exporting individual elements as in an overall system this could probably result something like the following code: ```python # Sharpie tool object setup, create all your design meshes through Sharpie before attempting this section. for mesh_object in outer_surface_meshes: layer_height = layer_settings[mesh_name] filename_string_list.append(f'{mesh_object}_out') filename_prefix_list[mesh_name].append('SharpieOutputOutfile') # Save individual previews. Use the Sharpie’s mesh creation method (with some customization), so this works well when not attempting an automated batch. outer_surface_meshes = [] sharpie.create_outer_surface(mesh_object.points_with_normals(), [MeshEdge(sharpie.line(points)]) ```
