AI Isometric Estimation
for Industrial Projects
The Takeoff AI estimates from your isometrics by measuring lengths, counting fittings and welds, totaling dia-inch and building a priced MTO for material and labor pricing.
Only AI That Estimates From Isometrics
The Takeoff AI traces every count and every measurement back to the drawing.
Click any number in the MTO and it shows you exactly where on the iso it came from, so you verify instead of trust.

The Takeoff AI carries the iso all the way to cost
The Takeoff AI first runs a material takeoff from your isometrics, then derives the hardware nobody draws, estimates labor hours, and prices it all so you get a number you can bid.
Frequently asked questions
The Takeoff AI estimates every line in the iso package by counting pipe by size, spec and schedule, along with fittings, flanges, valves and in-line specialties, quantified per line and rolled up across the set.
Yes, The Takeoff AI can estimate packages of any size with every quantity traceable to the line and sheet it came from.
Yes. The Takeoff AI can use your rate book for material pricing and your own productivity factors on top of MCAA-seeded labor units.
Email your isos to marketing@thetakeoff.ai and we'll run the full estimate, material, labor, and pricing, so you can compare it against your own numbers.
