Navisworks and other coordination platforms may be used depending on project requirements.<\/p>\n<h3 dir=\"auto\" data-section-id=\"13dzo6w\" data-start=\"18756\" data-end=\"18794\">Why is HVAC shop drawing important?<\/h3>\n<p dir=\"auto\" data-start=\"18796\" data-end=\"19010\">HVAC shop drawings provide detailed construction information for ductwork, piping, equipment and installation. They help the project team coordinate and understand the intended installation before work is executed.<\/p>\n<h3 dir=\"auto\" data-section-id=\"1mwkpsm\" data-start=\"19012\" data-end=\"19054\">Does HVAC drafting include duct design?<\/h3>\n<p dir=\"auto\" data-start=\"19056\" data-end=\"19245\">HVAC drafting can represent duct design through layouts, dimensions, sections and details. The underlying engineering design and sizing should come from the responsible HVAC design process.<\/p>\n<h3 dir=\"auto\" data-section-id=\"k45p7c\" data-start=\"19247\" data-end=\"19282\">Can HVAC drafting be done in 3D?<\/h3>\n<p dir=\"auto\" data-start=\"19284\" data-end=\"19401\">Yes.
