Features

Everything you need to estimate and build

From slab to roof, every profile, every fastener, every weight. Plus full structural verification, hybrid concrete and BIM export.

▢

Parametric 3D Design

Walls, doors and windows on a configurable slab. Auto-generated structure: studs, tracks, headers, jacks, cripples and blocking.

☰

Automatic BOM

Exact PGC/PGU profile count by type and size. Linear meters, 6m bars, total weight. Updates in real time.

$

Barbieri Pricing

Integrated catalog with technical specs. Cut optimization to minimize waste. Offcut reuse.

⚙

Layer System

Configure exterior/interior layers: cement board, OSB, membrane, fiberglass, vapor barrier, gypsum. 3D visualization + fasteners.

⚖

CIRSOC Analysis

Wind (CIRSOC 102), seismic (103), snow (104), thermal (IRAM 11601/11605). LRFD combinations. Stud and deflection verification.

↑

Multi-Story + Roof

Up to 3 stories with intermediate floor joists. Roof with Fink, Howe, Pratt and King Post trusses. Straight, L and U stairs.

▣

Zoning (FOS/FOT)

Lot setup with front, back and side setbacks. Automatic floor-area-ratio calculation with compliance indicator.

▩

Party Wall + Acoustics

Double party wall with fire-rated gypsum (F60). IRAM 4044 acoustic verification with R'w estimation between dwellings.

⍗

Point Loads

Water tanks placed on the roof. Per-truss load analysis with reinforcement recommendation by weight.

☷

Prefab Panelization

Automatic wall splitting into transportable panels (max. 2.40m). Panel list with weight and parts for the shop.

◆

Advanced Structural Analysis

Header verification (CIRSOC 303), lateral bracing with shear walls, IRAM 4044 acoustic analysis, SF vs masonry comparator with usable-area gain.

◢

Angled Walls

Free-form design with walls at any angle. 45° snap with Shift, 5° with Alt. Ideal for L-shaped houses, irregular frontages and non-orthogonal lots.

█

Concrete + Steel Frame

Hybrid system: reinforced concrete ground floor (H13–H30, 12–40 cm), upper floors in steel frame. Automatic weight and footing calculation.

⇄

Professional Export

DXF for AutoCAD, IFC for Revit/ArchiCAD/BIM, PDF with drawings + BOM + structural analysis + cutting diagrams. DXF import for surveyor lot outlines.

⛺

International

Support for Argentina (Barbieri + CIRSOC), Chile (Metalcon + NCh 432/433/431), Uruguay and Paraguay (compatible profiles). Local catalogs and codes.

Integrated CIRSOC structural analysis

No need to open another spreadsheet or look up tables. Analysis runs in real time on your design.

  • Dead loads computed from the actual wall layers
  • Wind pressure per CIRSOC 102 with per-city velocities
  • Seismic per CIRSOC 103: zones 0–4, soil types, equivalent lateral force
  • Snow per CIRSOC 104: zones 0–5, slope and exposure factors
  • Thermal per IRAM 11601/11605: U-value, bioclimatic zones, Level B
  • Acoustics per IRAM 4044: R'w estimation with mass law + cavity
  • LRFD combinations: 1.4D, 1.2D+1.6L, 1.2D+0.5L+1.6S
  • Stud, header (CIRSOC 303) and deflection (L/360) verification
  • Lateral bracing with shear walls (OSB sheathing)
  • Foundation: footing width per soil capacity, adjusted for concrete
  • International: NCh 432/433/431 for Chile, Metalcon profiles
