What do Construction Lines help with in technical drawings?

Construction lines are fundamental in technical drawings as they serve as guides that help the drafter accurately place and organize other lines and shapes within the composition of the drawing. These preliminary lines are typically light and are used for layout purposes, allowing drafters to ensure proper proportions, alignments, and relationships between different elements in the drawing. Once the main features and outlines are in place, construction lines can often be erased or faded out, leaving behind the final representation of the objects.

This guiding aspect is essential during the drafting process because it helps maintain the accuracy and balance of the design, allowing for complex shapes and structures to be constructed systematically and without distortion.
