Struttura — How to Use

Last Updated: January 1, 2026

Requirements

  • Revit 2023, 2024, 2025, 2026, or 2027
  • An architectural Revit model linked into your structural model
  • Structural column, beam, floor, and footing families loaded in the host model

Workflow

Struttura follows a sequential 4-step workflow. Run the commands in order for best results.

Step 1 — Framing from Walls

What it does: Reads architectural wall centerlines from the linked model and creates structural framing in three sub-steps:

  1. Perimeter columns at wall endpoints — spanning the full wall height (below base by beam depth, up to wall top minus top offset)
  2. Beams at every floor level the wall passes through, plus the actual wall top
  3. Intermediate columns inside each bay where wall length exceeds the max spacing

How to run:

  1. Open Revit with your structural model and linked architectural model loaded
  2. Click Avant Leap → Struttura → Framing from Walls
  3. Select the linked model, column family type, and beam family type
  4. Set max column spacing (default 3.0 m) and top offset (default 150 mm)
  5. Click Run

Step 2 — Floors from Arch

What it does: Reads floor outlines from the linked architectural model and creates structural floor slabs at the matching host levels.

How to run:

  1. Click Avant Leap → Struttura → Floors from Arch
  2. Select the linked model and structural floor type
  3. Click Run

Step 3 — Foundations from Columns

What it does: Places isolated pad footings under every structural column in the host model. Foundation size is automatically calculated from the column cross-section dimensions.

How to run:

  1. Click Avant Leap → Struttura → Foundations from Columns
  2. Select the foundation family type and set foundation thickness (default 450 mm)
  3. Click Run

Note: Run this command AFTER Step 1 (Framing from Walls) so structural columns exist in the model.

Step 4 — Validate Alignment

What it does: Compares structural elements in the host model against architectural elements in the linked model and reports misalignments that exceed the tolerance threshold.

How to run:

  1. Click Avant Leap → Struttura → Validate Alignment
  2. Select the linked model and set alignment tolerance (default 50 mm)
  3. Click Run
  4. Review the misalignment report in the results dialog

Tips

  • Always run build.bat and deploylocal.bat before testing updates
  • Use Add-In Manager (Add-Ins → External Tools → Add-In Manager) during development to reload the DLL without restarting Revit
  • If the linked model has no structural column/beam families loaded, add them first via Insert → Load Family
  • Foundation thickness drives the vertical offset — increase if footings overlap with the floor slab
