Measured and design profiles
The measured profile represents the surveyed geometry at a station. The design profile is the reference section applicable there.

A cross-section is meaningful only when its location, orientation, source surface and design reference are clear.

The measured profile represents the surveyed geometry at a station. The design profile is the reference section applicable there.
Overbreak identifies excavation beyond design; underbreak identifies areas where the excavation has not reached it. Interpret both with the agreed tolerance.
Horizontal, vertical, normal and radial distances are not interchangeable. Use a direction and origin appropriate to the floor, roof, sidewall or curved region.
Review the progression of cross-sections along the alignment and the corresponding floor and roof trends.
Distinguish missing data from a real surface. Do not silently close an unmeasured region without a documented criterion.
Keep station, orientation, design revision, tolerances and source references with exported profiles and tables.
Request a technical evaluation focused on cross-sections, as-built versus design comparison, quantities or traceable deliverables. The 15-day evaluation period begins when the licence is activated, subject to prior coordination and availability.
No automatic download. Commercial licensing and deployment scope are agreed after technical review; no unverified price or guaranteed outcome is advertised.
