Which craft professional requires knowledge of blueprint reading and geometry?

The craft professional who requires knowledge of blueprint reading and geometry is the pipefitter. In pipefitting, workers must read and interpret blueprints and schematics to understand how pipes will be laid out in a structure. This involves comprehending specifications related to dimensions, fittings, and piping systems.

Geometry is crucial for pipefitters as they often need to calculate angles and dimensions to ensure that pipes fit properly in tight spaces and align with the overall design. They may need to figure out precise measurements to ensure that pipes connect at the correct angles and elevations, which requires a solid understanding of geometric principles.

While other trades like carpentry, welding, and roofing also involve some level of blueprint reading and measurement, the specific reliance on geometry for calculating angles and spatial arrangements is particularly pronounced in pipefitting.
