Structural Drawings
•Assembly Drawing Skeleton assembly drawing showing the relationship of variousparts to be fitted together in the finished structure
• Engineering Design Drawing
Plan view (top view), Elevation view (front view), Bottom section (bottom view) shows overall dimensions, location and size of columns, beams, angles, ….. , Detail of connections, typical cross sections, various notes.
• Manufacturing (shop or working) Drawing
Detail drawing of all parts of the structure, all dimensions to the nearest 1/16 “, location of all holes for connections, detail of the connection parts, required sizes of all materials

Trusses – A truss is a configuration of structural elements (triangle) that adds strength to a support, bridges and roofs.
Truss members carry tension or compression loads, no bending.
