Rebuilding a legend since 2005
Not an update. A new era of engineering.
Two decades of trust, two years of rebuilding. SOLE Suite 2026 is a completely new platform — a native DWG workspace with real-time visual automation. Leading it: SOLE Ultimate, the all-in-one civil engineering solution.

The individual editions
Four modules.
One unified CAD engine.
Every edition runs inside the same native DWG drafting environment, with the engineering modules its discipline actually needs. Take one on its own — or take all four in Ultimate.
The flagship
SOLE Road Design
The complete highway engineering suite. Automatically coordinates curves, profiles, cross-sections and pavement layouts.
- Real-time side-slope & drain previews
- Dynamic, IRC-compliant curves
- Auto plan-generation on L-sections
- Multiple roads in a single project
Included in Ultimate
The core suite
SOLE Professional
Engineered for surveyors, land partition planners and drafting bureaus. Focused on terrain modelling, contours and volumes.
- Elevation colour-shaded contour bands
- Dynamic include/exclude boundary regions
- Plotting from coordinate bearings
- DTM quantity and grid calculation
Included in Ultimate
The specialist
SOLE Canal
Tailored for irrigation engineering. Speeds up template-driven channel section modelling and earthwork.
- Canal & channel templates
- Side-slope lining & berm configurations
- Cut/fill area computation tables
- Direct CAD drawing export
Included in Ultimate
Networks
SOLE Piping
Water-supply and sewerage network design, carried into the 2026 engine.
Full module detail publishes with launch.
Included in Ultimate
Re-engineered architecture
The pillars of change
We spent two years redesigning the engine to resolve historical friction points and build a future-proof drafting system.
Familiar CAD editor
A full AutoCAD-style editing workspace with a command line, snaps, custom hatches, printing layouts and native DWG compatibility built in.
Live feeds & previews
Say goodbye to the generate-and-check cycle. Cross-sections, vertical profiles and slope lines update in real time as inputs are adjusted.
Limitless corridors
Engineered to handle large-scale alignments and surveys without lag. Generates high-fidelity drawing layouts and vector PDFs instantly.
Legacy compatibility
Migrate your active projects smoothly. Open your twenty-year-old .SLP files directly in the new suite, with zero data loss.
An exclusive upgrade path for existing clients
Current licence holders get a priority window to migrate their legacy configurations to the 2026 suite at special pre-launch rates — before general availability.
The 2026 suite moves to an annual subscription. We will walk you through exactly what that means for your existing licence, and carry your settings and .SLP projects across.
