When fabricating spooled pipe, which drawing type is used?

• A. Isometric
• B. Orthographic
• C. Isomatric
• D. Plan

Answer: (C)

When fabricating spooled pipe, you want a drawing that shows the actual 3D path of the piping in one view. An isometric drawing provides that by presenting three axes at equal angles so pipe lengths, diameters, and angles read true in a single view. This lets fabricators see exactly how each spool runs from start to finish, where fittings and welds occur, and how pieces fit together in the real layout. Orthographic plans show separate front, top, and side views, which can make it harder to visualize the true route of the pipe; plan drawings are typically overhead layouts that emphasize location rather than three-dimensional shape. The term in the option set is a common spelling variation of the standard isometric drawing, which is why that choice is correct for spooled pipe.
