Trying to identify some old 3D model set.

[amccour]

Probably a long shot, but I was going through an old IMSI Floorplan 9 install I had, looking for some models I used to use back in the day to mess with in Sweet Home 3D.

In addition to whatever models I'd downloaded back then, I noticed there were a bunch of bundled furniture .3ds files named things like S3D-#### (so, S3D-0114.3ds, S3D-0116.3ds, etc.) and some documentation indicating there would've been around 1,200 models in total, but it looks like the install CD only came with around 300.

Anyone familiar with older CAD/home design software know where the full set may have originated from? Or who even made them, for that matter -- the copyright information is not at all clear if they were some bespoke IMSI thing or if they were licensed from elsewhere.

Assuming these were proprietary so absolutely not asking for anything pirated if that's the case, just information on where the full set may have originated from.
