Simplify Tie-Ins. Accelerate Projects. Reduce Risk.

eserv's Tie-In Point Calculator is a powerful plugin for Autodesk® AutoCAD® that removes the guesswork from connecting new pipework to existing infrastructure. Its guided calculation workflow makes the process faster, easier, and more reliable — reducing the risk of error and the need for rework.

Manual tie-in point calculations are time-consuming, repetitive, and require deep expertise. Our tool automates this complex task, helping you get accurate results the first time. That means less clicking, less second-guessing, and more time spent on high-value design work.

With features that support data reuse, eliminate repetitive keystrokes, and guide users through each step, the Tie-In Point Calculator boosts efficiency and consistency — empowering both experienced engineers and new users alike.
