A 3D Workflow for AHU Selection: What to Evaluate

A 3D layout can help a team discuss an air handling unit's shape, arrangement and component sequence. Its usefulness depends on how well the model supports the decisions your engineers need to make.

Evaluate the geometry

Use one of your actual casing ranges. Review dimensions, component positions and connections, then identify allowances or manufacturing details that require further engineering. A visual model is not a substitute for an approved production drawing.

Evaluate changes

Adjust a unit requirement and follow the change through the layout, component results and documents. Note which steps are automatic and which require review. Use this exercise to identify the workflow that fits your team.

Evaluate the handoff

Inspect the PDF and DXF with the people who will use them. Confirm units, drawing conventions, revision references and document content. Any BIM, spreadsheet, pricing or production-system requirements should be agreed separately in the project scope.
