Drafting
Without the
Overhead.
Skip the software, skip the hiring, skip the overhead. Gridline gives sheet metal contractors fast, accurate HVAC drafting support — so you can focus on winning jobs and getting the work done.
Everything
You Need.
From shop drawings to as-builts — we handle the drafting so you can focus on the field.
Fully detailed ductwork layouts — fittings, duct runs, and custom fabrication details — coordination-ready and field-installation-ready. No guesswork, just drawings that work.
Clash-aware layouts built to work with other trades. We handle the coordination so you stay off the conflict list on job day.
Updated drawings based on field changes. We take your redlines and turn them into clean, permit-ready as-builts fast.
Got markups from the field or the GC? We turn redlines into updated drawings quickly — no delays, no drama.
We perform accurate duct takeoffs and convert them into fully detailed, fabrication-ready MAJ files for the shop — so your fabricators get exactly what they need, no interpretation required.
We run coordination for all MEP trades — managing clash detection, weekly model updates, and trade meetings so the job stays on track and off the conflict list.
