Sheet Metal Takeoff Software for Duct and Fitting Quantities
DuctIQ is sheet metal takeoff software for HVAC ductwork. It reads the mechanical drawing, measures the duct, counts the fittings, and — because the shop needs more than quantities — turns the takeoff into fabrication-ready shop drawings.
That makes it useful on both sides of the shop wall: the estimator gets quantities to bid, and the shop gets dimensioned fittings to build.

Quantities for the bid, details for the shop
A sheet metal contractor needs two things from a drawing. To bid, you need duct linear feet by size and a fitting count. To fabricate, you need each fitting dimensioned with a gauge, a material, and a connection type. Most takeoff tools stop at the first and leave the shop to redraw everything.
DuctIQ carries the takeoff through to fabrication. The same measured duct and counted fittings become shop drawings with the callouts a fab shop actually cuts to.
Fabrication-ready shop drawings
Each fitting drawing carries a fabrication spec — gauge, material, seam/connection, and quantity — and the cut dimensions in the A×B / C×D convention shops use. Where a gauge is not given on the drawing, DuctIQ shows the SMACNA minimum and labels it clearly as a minimum rather than a verified value, so nobody mistakes a default for a spec.
- Duct measured in linear feet by size.
- Fittings counted and rolled up by type and size.
- Per-fitting fab spec: gauge, material, seam, quantity.
- Cut dimensions in the A×B / C×D convention.
- SMACNA minimum gauge shown and labelled when the drawing does not specify one.
Built for HVAC sheet metal, not generic takeoff
Because DuctIQ is purpose-built for HVAC ductwork, it understands the difference between a supply trunk and a return, a reducer and a tee, a rectangular run and a round one. That structure is what makes the takeoff usable for both the bid and the bench.

Frequently asked questions
Does DuctIQ produce shop drawings or just quantities?
Both. You get reviewable duct and fitting quantities for the bid, and fabrication-ready shop drawings with gauge, material, and seam callouts for the shop.
Where does the gauge come from?
When the drawing or schedule specifies a gauge, DuctIQ uses it. When it does not, DuctIQ shows the SMACNA minimum for the size and labels it as a minimum so it is never mistaken for a verified spec.
What dimensioning convention do the drawings use?
Fittings are dimensioned in the A×B / C×D convention used on shop tickets, including both ends, length, and offsets where they apply.
Does it handle round (spiral) as well as rectangular?
Yes. Both rectangular and round/spiral duct and fittings are supported.
Can I export the quantities to Excel?
Yes. The takeoff exports to Excel and CSV for pricing and purchasing.
