How to restore a 2004 .win object to life

Ignacio Azpiazu — Mon, 01 Dec 2025 17:57:40 GMT

I had a fancy Siding Maker (original by Mike Rensing, and I had created variations for other sidings) .win object (it used wallholes to cut the wall to produce the siding profile) that stopped working for corners (so stopped being usable really) when Archicad switched to building materials. I am wondering how it might work or not with complex profile walls.
I can't load a .win object from AC27. How should I go about it?

Hi,

I just added an old .win object from 2003, into the library of an Archicad 27 file, it reads it fine, the GDL code of old objects still works in newer versions of Archicad, so they should work unless it requires an API.

i made a new folder,

New Folder (6) on my desktop

added the .win file into the folder,

then added the folder as a library,

the object appeared in the windows tool.

I hope this helps

The oldest version Ac27 reads is Ac17.

Download and use Ac26 for this purpose; it reads versions as old as Ac8.1, if I remember correctly.

This is true for .PLN files, but the original poster is talking about window object files?

I am not familiar with '.WIN' files, but I know in the early days, objects had different file extensions, not just '.GSM' like today.

Old objects should open fine in newer versions if they are in a loaded library.

Barry.
