Seequent’s OpenGround Civil 3D Extension links live geotechnical data from OpenGround into Autodesk Civil 3D, allowing borehole logs, interpreted strata and lab test results to update directly within corridor, grading and earthworks models. Designers can generate 3D ground models, cross-sections and surfaces that automatically reflect new investigations, rather than relying on static AGS or CSV imports. The workflow reduces manual rework and helps geotechnical and civil teams keep alignments, cut/fill volumes and foundation layouts consistent with the latest ground model.

Scripting in RS3 now lets tunnel designers automatically extract lining forces, moments, and displacements at every section along a 3D model, instead of manually interrogating individual cross-sections. Users can generate full lining design envelopes, export results to spreadsheets or custom reports, and rapidly iterate on reinforcement or segment thickness without re-running the finite element analysis. For geotechnical teams, this shifts effort from repetitive post-processing to checking design assumptions, load cases, and ground–structure interaction behaviour across the entire tunnel.

GeoDin Ground, a free Autodesk Civil 3D plug-in, replaces manual borehole imports by directly linking Civil 3D models to GeoDin® geotechnical databases and AGS/Excel borehole logs. The tool generates dynamic 3D subsurface models, including stratigraphy, groundwater levels and geotechnical layers, that update automatically as borehole data change. For designers, this means borehole positions, interpreted soil horizons and material properties are embedded in corridors, alignments and earthworks, reducing data re-entry and improving consistency between geotechnical interpretation and Civil 3D design.
