Parametric modeling of hydraulic flumes, channels & structures in AutoCAD & Civil 3D
NM Hydraulic Builder enables creating, customizing, and connecting hydraulic components within an intuitive visual interface featuring sketch, plan, section, and 3D views. It combines a library of configurable elements with a custom family editor to build specialized fittings and generate native 3D solids directly in your drawing. Tailored for civil engineers, designers, and draftspersons looking to accelerate geometric modeling for drainage, conveyance, and irrigation projects.
Discover parametric channel modeling, hydraulic structure libraries, adaptive chamber wall cutouts, and native DWG 3D solid compilation in Civil 3D & AutoCAD.
Comprehensive tour showing workspace, sketches, channel modeling, structure connections, and 3D solid generation.

NM Hydraulic Builder dramatically reduces repetitive manual drafting when modifying dimensions, reusing components, and coordinating intersections.
Rectangular, trapezoidal, and triangular flumes with editable slopes and thicknesses. Smooth circular and dual-wall corrugated HDPE with drainage perforations.
Junction chambers, flume transitions, 45° wingwall headwalls, stepped energy dissipation chutes, and drop boxes with stilling basins.
Freeform modeling through interactive 2D sketchers (Bézier curves, formula dimensions), extrusion, revolution, variable sweep, and shell hollows in .nmhc.
Automatic chamber wall openings adapting dynamically to incoming flume or pipe dimensions, with precise invert elevation lock and lateral offset alignment.
Direct binding to Civil 3D horizontal alignments and vertical design profiles for 3D pathing, longitudinal grades, and expansion joint modulation.
Controlled creation of native AutoCAD 3DSolids with collision diagnostics and transaction-safe automatic rollback if any error occurs.
