A growing suite of tools for Autodesk Civil 3D that helps design teams move faster through grade planning, routing analysis, constructability reviews, and project submittals — all from inside your drawing.
GLD Tools covers the full lifecycle of civil infrastructure design — from early-stage route assessment through to final cross-section deliverables. Built to save hours on every project.
Browse, filter, and manage alignments across your drawing. Quick-select any alignment and jump directly into profiles, corridor setup, or cross-section extraction.
Coming SoonInteractive PVI table with real-time grade analysis, deflection calculations, and integrated charting. Edit elevations and write changes back to Civil 3D instantly.
AvailableGenerate optimized profiles from surface data with intelligent PVI placement. Define cover constraints and let the tool handle the vertical geometry.
AvailableStreamlined corridor modelling with preset assemblies and batch processing. Reduce repetitive setup and maintain consistency across complex linear projects.
Coming SoonAutomatic bend compliance checking against configurable pipe specifications. Separate sag and overbend limits with hot-bend whitelisting for exempt station ranges.
AvailableExport profile data, PVI tables, and compliance reports to Excel or HTML with five professional color themes. Clean, branded reports ready for client submittals.
AvailableExtract and manage sample lines, cross-section views, and section data. Generate cross-section reports for constructability reviews and earthworks planning.
Coming SoonCompute cut/fill volumes between surfaces or along corridors. Generate volume summary tables and mass haul diagrams for grading and earthworks estimates.
Coming SoonSpecialized tools for pipe-specific design tasks — joint deflection tables, wall thickness checks, buoyancy analysis, and cover verification against spec requirements.

GLD Tools is designed around how design teams actually work. Each tool targets a specific bottleneck in the Civil 3D workflow, eliminating the spreadsheet workarounds and manual steps that slow down project delivery.
Whether you're running a preliminary route study or producing final construction drawings, GLD Tools accelerates every phase.
Design vertical profiles with instant deflection feedback and spec compliance. Iterate faster with direct Civil 3D write-back.
Evaluate alignment options quickly. Compare profiles, check constructability constraints, and generate comparison reports.
Flag bend exceedances, steep grades, and specification violations before they reach the field. Catch issues early.
Generate polished Excel and HTML reports with professional themes. Ready for client review meetings and regulatory submissions.
GLD Tools gives your design team the Civil 3D power-ups they've been asking for. Grade planning, compliance checks, corridor modelling, and clean exports — all in one plugin.
We build tools for the engineers who build infrastructure. Ground Level Design Inc. develops professional-grade software for civil engineering and linear infrastructure design, with a focus on Autodesk Civil 3D integration.
GLD Tools grew out of real project demands — the everyday friction of managing profiles, checking specs against spreadsheets, building corridor models from scratch, and generating clean deliverables under tight deadlines. We built what we needed, then made it available to every design team working in Civil 3D.
