Simple Duct Layout

Plan duct runs visually.

DuctPrint is a duct layout tool built for HVAC and sheet-metal workers. Place fittings, connect duct runs, enter real measurements, create takeoffs, and turn your layout into a drawing you can actually use.

Launching soon on the App Store and Google Play — built for the field, the shop, and the office.

Features

Everything you need to lay out a duct run

DuctPrint works the way ductwork actually goes together — fittings that understand each other, real sizes, and a drawing you can take to the field.

Visual duct layout

Build a full duct run on a drawing grid instead of holding it in your head or sketching by hand.

Drag-and-drop fittings

Pick from a library of real HVAC fittings, drop them on the grid, and drag them into place.

Automatic connections

Fittings understand how they join. Drag one onto a compatible opening and they snap together.

Automatic size inheritance

Attach a fitting to a 20" × 14" duct and it can take that size automatically — no re-typing the same numbers.

Rectangular & round duct

Work in rectangular or round throughout the run, with fittings sized to match each connection.

Full fitting library

Elbows, transitions, offsets, tees, taps, canvas connectors, dampers, VAV boxes, flex, and more.

Measurements & dimensions

Edit width, depth, diameter, length, throat, offset and more, then place dimensions right on the drawing.

Automatic duct takeoff

Generate a takeoff from your layout — fitting type, size, length, and quantity — as you build.

Print & PDF

Print the full layout or a selected area, choose orientation and fit-to-page, toggle grid and dimensions, and save as PDF.

iPad & touch-friendly

Large touch targets, drag-and-drop, and snapping designed to be practical on an iPad in the field.

Flagship feature

Fitting Detail Sheets

Turn a finished duct layout into fabrication-ready paperwork — automatically.

Every fitting on your drawing — elbows, transitions, tees, taps, VAVs — gets its own clear, correctly-dimensioned drawing the moment you open Share / Print. No re-drawing, no manual redlining, no separate shop sheet to build by hand.

How It Works

From blank grid to finished drawing

A straightforward flow built around how ductwork is actually put together.

1

Choose a fitting

Pick from the library of real duct fittings.

2

Place it on the drawing

Drop it onto the grid where you need it.

3

Connect it to your run

Drag it onto a compatible fitting and it snaps together.

4

Enter or inherit the size

Type the dimensions, or let it take the size of the duct it joins.

5

Keep building the run

Add elbows, transitions, taps and tees to change direction and branch off.

6

Add dimensions

Place measurements to show distances between points.

7

Review the takeoff

Check the automatically generated list of fittings and sizes.

8

Print or save the drawing

Print the layout or export a PDF to use in the field, shop, or office.
