Pipe2CAD is a popular free AutoCAD add-on tool used by civil and environmental engineers to streamline the design and documentation of pipe networks. It primarily serves as a bridge between specialized hydraulic calculation software and production-ready engineering drawings. Key Features
Hydraulic Software Integration: It imports complex network data directly from hydraulic modeling packages (such as EPANET .inp files, SewerGEMS, shapefiles, or plain text data) into the AutoCAD workspace.
Automated Profiles and Plans: The software instantly converts layout data into fully formatted 2D plans and longitudinal profiles (cross-sections) required for formal project submittals.
Interference & Conflict Checking: It scans different utility layouts (e.g., matching a water supply line against a sanitary sewer network) to highlight geometric conflicts and physical interferences.
Dynamic Network Editing: Users can add, delete, or alter pipe properties, lengths, slopes, and fittings directly inside AutoCAD, and the labels and documentation auto-update dynamically.
Pressure Network Verification: It helps quickly cross-check critical low and high pressure points across a water distribution system. Who Uses It?
It is heavily utilized in wet infrastructure workflows—specifically for mapping out water supply lines, sanitary sewers, and storm drainage systems. Because it is a freeware utility, it is a highly popular alternative for engineers who need to generate clean profiles without relying on heavier, more expensive suites like Civil 3D.
