This instructional module aims to delve into the concept of elevations and their importance in the context of estimating. The focus will be on executing elevations in a systematic front, right, rear, and left pattern to enhance precision. The module will explain the significance of employing annotation tools, including ellipses, text, and arrows, to facilitate accurate estimating processes. Furthermore, the course will provide a comprehensive understanding of vertices and their practical applications. Vertices are instrumental in the modification of 90-degree angles through precise interventions, enabling the manipulation of walls, rooms, roofs, areas, and blocks to achieve the desired overall shape.
