Think about how many faces, how many edges, and how many points the video card alone must generate! I’ve seen a 30in x 29.5in plate that had 3,500+ holes and weigh over 10MB. While the part itself is nothing more than a plate with holes in it and is not much to sketch and pattern - this geometry in CAD is a monster! It is commonly used for fences, walkways, grates, and as metallic lath to support plaster or stucco. Expanded metal is a type of sheet metal that has been cut and stretched to form a regular pattern to look like a mesh.
