... I spotted the following application. It is open source, it runs on windows, mac and linux, and it is free.
http://www.blender3d.org
Using this application, I could re-write a Dosch .3ds file as suggested here, importing it and then exporting it into another .3ds file. This time, the AC10 plugin "3dImport" managed to read the file and import it. A few statistics on file size:
original .3ds: 388KB
exported .3ds: 377KB (via Blender3D)
converted .gsm: 3.2MB (via 3Dimport)
Comments:
1. what whent wrong with the conversion? The file is huge and the object takes ages to render on screen via the open-library-object menu, and there was no fortune in persuading AC10 to list it in the local library.
2. AC can read and write .dwg files natively. How about doing the same for .3ds files? It would be a dream to just drop the (usually large) collection of objects into the library, and use it on the fly, with no need for conversion. As the above application is open source, and it includes a (fast) reader of .3ds (and other) files, I think it is possible for ArchiCAD to be extended with a revised version of the open source code... and use .3ds natively for its libraries.
3. out of my chest, the gallery at Artlantis is inspiring, but how do we get there? I mean, those are .3ds file objects, right? How can I possibly convert hundreds of .3ds files with the above method, which take gigabytes in their non-converted format, persuade AC10 to use them swiftly, and then convert to artlantis? It is realistic, or they are using another method?
Finally, AC10 uses LightWorks for its rendering, LW is compatible with .rpc objects, as shown in the following page, but AC10 cannot load .rpc libraries . Why?
