Field notes

The catalog spans tasks from pipe intersections and duct elbows to stair stringers, block-wall layouts, and electrical conduit bends. For large patterns, the printing instructions describe tiled A4 pages, registration marks, and a 100 mm scale check; the site also says DXF saving is available. Its operator identifies the project as run by WEB PREPA, a Fukuoka web-production office, and warns that calculated results are estimates to verify before fabrication.
