Sewer GEMS To Civil 3D

Reverse-import a SewerGEMS gravity network straight into AutoCAD Civil 3D, keeping the model's own rim and invert elevations instead of recomputing them. Read the network, preview it, build the shop drawing if you need one, then export a native Civil 3D pipe network.

The workflow

Four stages, in the ribbon's own order

The ribbon tab has one button per stage. Each stage opens in its own small window; Back and Next walk the workflow.

Input · Object Reader

Read the SewerGEMS network geometry from a shapefile (Conduits/Manholes), a DXF export, or a PDF network plan.

Drawing · Preview

Review the network summary, elevations and validation issues before anything is built.

Shop Drawing

Alignments, Profiles and Profile Views — produce the shop-drawing views, grouped by direction or by street section, if you need them.

Output · Export to Civil 3D

Write the network out as a native Civil 3D pipe network: real pipes and structures, not blocks.

Source-truth elevations

Rim and invert elevations come from the SewerGEMS model itself, not from a recomputed hydraulic run.
Pipes keep their own slope and the structures their own depth — no silent rounding.
An outfall with no structure in the source is recovered from the pipe ends, so nothing is left dangling.
SHP, DXF or PDF plan input, so the network you already have is the one that gets read.

A real Civil 3D pipe network

Pipes and structures are native Civil 3D parts, picked from your part catalogue — not drawing blocks.
Shop-drawing alignments and profile views group by direction or by street section, your choice.
Profile views carry the design, crown and rim reference lines alongside the pipe itself.
Works alongside Water GEMS To Civil 3D and Clashes in the same drawing and Model Space.

Manual Civil 3D import vs. Sewer GEMS To Civil 3D

The same network, two ways

A recorded walk-through in Arabic: the routine manual Civil 3D GIS import, next to the automatic export from EGS IS.
