3D Modelling is the accepted practice for generating and designing connections as well as detail and gather sheets. This process helps in connections calculations identifying erection issues, generating detail sheets and CNC exports, applying piece marks and sequencing and various other detailing aspects.

3D modeling involves the addition of beams, columns, braces, stairs, ladders, plates, handrails and connection material with the help of 2D structural design drawings and reference models.
