Cut/Fill Slopes & Stepped Benches Panel
Set independent cut and fill H:V slope ratios, maximum bench heights, bench widths, and transverse slope gradients.
Dynamic slopes, multi-tier benches, channels & real-time live volumes for Civil 3D
Streamlines earthwork grading design in Autodesk Civil 3D with a dedicated solution for creating platforms, projecting cut/fill slopes, and solving complex multi-tier benches, berms, and drainage channels. NM Plataforma Dinámica unifies grading parameters, graphic preview, and instant volumetric computation into a single reactive panel: as you adjust base geometry, elevations, slopes, or bench widths, cut, fill, and net earthwork volumes are calculated and displayed automatically in real time—eliminating the need to generate TIN volume surfaces or manually compare surfaces in Civil 3D's Volumes Dashboard. Includes one-click mass auto-balancing and an advanced Dynamic Pond module.

Set independent cut and fill H:V slope ratios, maximum bench heights, bench widths, and transverse slope gradients.

Integrate triangular V-ditches or trapezoidal drainage channels with customizable bottom width and side slopes.

Cut, fill, and net volumes are automatically calculated and updated live in the panel as you adjust elevations, slopes, or dimensions, completely eliminating the need to create volume surfaces or compare volumes. Includes one-click elevation auto-balancing.

Cycle through stations with live section inspection and project proposed grading as a ghost profile onto profile views.

Specialized pond basin module with perimeter access ramp, internal slopes, safety berms, water surface elevation, and storage capacity curve.

Exports geometry directly to native Civil 3D TIN surfaces, 3D featurelines, and standard slope pattern tadpoles.
A responsive alternative to traditional Civil 3D grading, eliminating repetitive steps and keeping all design elements synchronized.
Define independent H:V ratios for cut and fill conditions, customizing bench heights, widths, and slope gradients.
Inspect cut, fill, and net earthwork volumes updating live in the panel as you change elevations or slope ratios—no need to create volume surfaces or compare them in the Volumes Dashboard. Compute the optimal balance elevation in a single click.
Embed triangular V-ditches or trapezoidal drainage flumes with customizable geometry directly on benches or slope toes.
Design retention and tailings basins with perimeter access ramps, internal slopes, safety berms, water level, and storage capacity.
Step through stations with instant cross-sections and display the proposed grading as an interactive ghost profile overlay.
Generate native Civil 3D TIN surfaces, 3D polylines, FeatureLines, and standardized slope pattern hatching (tadpoles).
