Lo cuelgo aquí por si alguno tiene clientes de obra o trabaja con proyecto ejecutivo donde el andamiaje es parte del entregable.

Es un addon de Blender (gratis también) que genera andamios multidireccionales paramétricos del sistema Layher Allround, los verifica estructuralmente según Eurocódigo, y exporta planos CAD A3 normativos junto a una memoria HTML con visor 3D.

Pensado más para ingeniería que para arquitectura, pero si trabajáis con dirección de obra o BIM ejecutivo puede sumar.

Gratis, offline, sin cuenta. Tengo curiosidad, ¿alguno modeláis el andamiaje en proyecto o lo dejáis al contratista?

A year of evenings later, here it is. A Blender addon that:

1. Builds a multidirectional scaffold along a path you define (Layher Allround parts, real dimensions)
2. Runs an FEM check on it per EN 1993 and EN 12811
3. Spits out A3 drawings (UNE-EN ISO 129-1) and a bill of materials
4. Auto-iterates the design until it passes

Costs nothing. MIT license. Runs offline. The 0.7.15 release installs the FEM library automatically when you enable the addon, no manual pip install nonsense anymore.

I built it because there's basically two options out there for scaffold design: pay 5 to 10k a year for Layher SIM or PERI CAD, or do it by hand on a Mathcad sheet. There should be an open option in 2026.

What I'd love from this sub:

• Critique on the verification approach (I'm Eurocode-only right now)
• Which catalog I should support next, Plettac, Cuplok, Kwikstage?
• Codes outside Eurocode worth porting

Civil engineer here. Spent the last year on this and finally pushed it public last week.

It's a Blender addon for designing multidirectional scaffolds (ringlock / Layher Allround). You define the path with empties, it instantiates the scaffold along it, builds a FEM model in PyNiteFEA, runs verification per EN 1993-1-1 and EN 12811-1, and if anything fails it auto-corrects iteratively. Exports A3 drawings with UNE-EN ISO 129-1 dimensioning, a BOM, and an HTML report with a Three.js viewer.

434 tests on the FEM/codification side. All Python, all readable. MIT license.

Posting here because I'd genuinely like this sub to tear it apart before I push it harder. Specific things I'm unsure about:

• Standard-to-ledger joints. I'm modelling them semi-rigid (calibrated against Layher's published test data) but I know that's a rabbit hole.
• Effective lengths for buckling derived from bracing topology. Works on the cases I've tested but no idea how it behaves on edge cases.
• I'm fully Eurocode-centric. What would the ANSI A10.8 / AS-NZS 1576 angle even look like? Don't have access to those codes.

Not selling anything, MIT, no account, runs offline. Just want it improved.

Most BIM workflows I've seen leave temporary works out entirely, or stick in a dumb Revit family. I've just open-sourced an addon for Blender that does parametric multidirectional scaffolds with a real structural check on top.

Layher Allround system, EN 1993 plus EN 12811 verification, A3 CAD drawings, BOM, HTML report. Free, MIT, runs locally.

Genuinely curious what your workflows look like.

Do you model scaffolds at all in your BIM, or is it just left to the contractor on site? Would IFC export help, is that worth me prioritizing? What about formwork and falsework, would the same approach be useful?

I'm a civil engineer. Decided a year ago to scratch my own itch: every scaffold layout tool I've used is either expensive proprietary software or some terrible Excel spreadsheet from 2007. So I built one as a Blender add-on, polished it, wrote 434 tests, and just put it on GitHub under MIT.

What it does, in plain terms: you draw a path in Blender, it builds a complete multidirectional scaffold along that path (real Layher Allround parts), then it runs a structural check on the whole thing per European code and tells you what's strong enough and what isn't. If something fails, it auto-corrects.

Stats:

• ~1 year of evenings/weekends
• 434 tests passing
• Zero users so far (today is launch day)
• 100% free, no SaaS, no upsell — landing page exists only to centralize docs

Looking for: first real users to install it and tell me what breaks. The audience is narrow (engineers, scaffolders) so I have to go find them in places like this.

Any feedback on the landing page or the README is gold.
