One plugin, every discipline

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.

🛣️

Alignment Manager

Browse, filter, and manage alignments across your drawing. Quick-select any alignment and jump directly into profiles, corridor setup, or cross-section extraction.

📐

Profile Designer

Interactive PVI table with real-time grade analysis, deflection calculations, and integrated charting. Edit elevations and write changes back to Civil 3D instantly.

Available

Auto Profile

Generate optimized profiles from surface data with intelligent PVI placement. Define cover constraints and let the tool handle the vertical geometry.

Available
⚙️

Corridor Builder

Streamlined corridor modelling with preset assemblies and batch processing. Reduce repetitive setup and maintain consistency across complex linear projects.

Coming Soon

Pipe Compliance

Automatic bend compliance checking against configurable pipe specifications. Separate sag and overbend limits with hot-bend whitelisting for exempt station ranges.

Available
📊

Engineering Exports

Export profile data, PVI tables, and compliance reports to Excel or HTML with five professional color themes. Clean, branded reports ready for client submittals.

Available
📐

Cross Section Tools

Extract and manage sample lines, cross-section views, and section data. Generate cross-section reports for constructability reviews and earthworks planning.

Coming Soon
📦

Volume Calculator

Compute cut/fill volumes between surfaces or along corridors. Generate volume summary tables and mass haul diagrams for grading and earthworks estimates.

Coming Soon
🔧

Pipe Engineering

Specialized tools for pipe-specific design tasks — joint deflection tables, wall thickness checks, buoyancy analysis, and cover verification against spec requirements.

From concept to
construction package

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.

  • Grade planning with real-time compliance feedback
  • Route assessment and constructability analysis tools
  • Corridor modelling with preset assemblies and batch creation
  • Professional exports for project reviews and client submittals
  • All settings saved per-drawing — no external config files

Built for the work you do every day

Whether you're running a preliminary route study or producing final construction drawings, GLD Tools accelerates every phase.

📋

Grade Planning

Design vertical profiles with instant deflection feedback and spec compliance. Iterate faster with direct Civil 3D write-back.

🗺️

Route Assessment

Evaluate alignment options quickly. Compare profiles, check constructability constraints, and generate comparison reports.

🏗️

Constructability Review

Flag bend exceedances, steep grades, and specification violations before they reach the field. Catch issues early.

📄

Project Submittals

Generate polished Excel and HTML reports with professional themes. Ready for client review meetings and regulatory submissions.

Ship deliverables faster, not harder.

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.

Ground Level Design Inc.

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.
