Draw the fitting clearly in a three-dimensional isometric layout orientation view.
['Draw the fitting clearly in a three-dimensional isometric layout orientation view.', 'Label all dimensions explicitly: Width (W) and Height (H) of all openings, Length (L) of the fitting body, the exact direction and dimension of any offset shift, the metal gauge needed, the insulation liner requirements, and the connection types explicitly noted at every single open face port.']
Use this as training guidance. The foreman, approved drawings, project specs, manufacturer installation instructions, employer safety policy, and AHJ/code requirements always control the final answer.
