The impact is particularly pronounced in complex plumbing systems where even minor discrepancies in individual components can compound to create significant overall design flaws. Free availability does not supersede the need for precise and reliable representations; in fact, the ease of access can make the issue of accuracy even more critical.
A scenario illustrating this significance involves the use of a freely downloaded library of pipe fittings. If the dimensions of a 90-degree elbow within this library are represented incorrectly, subsequent calculations of pipe length for a system requiring multiple such elbows will be skewed. This can result in insufficient pipe material on-site, requiring costly delays and modifications. Furthermore, such inaccuracies might not be immediately apparent during the design phase, only manifesting during the physical installation process, thereby increasing the cost and complexity of rectification. The issue extends beyond dimensional accuracy to include adherence to industry standards and correct representation of connection types and flow characteristics.
In conclusion, while the accessibility of two-dimensional AutoCAD plumbing component blocks obtained without cost provides substantial benefits in terms of design efficiency, rigorous verification of symbol accuracy is essential.
