Modules in SweetHome3d (Structural Design) and FreeCAD (Complete Model)
See parts of wall modules at Architecture Part Library.
Module Map - Exterior Wall modules - 1-23 are on the first floor - 24-47 are on the second, and the rest are 48-59 for first floor interior modules, and 60-69 are second floor interior modules.
These SweetHome3D files are extracted from the SweetHome3D technical design file for structure of Seed Eco-Home 2 - Seed Eco-Home 2 Technical Design of Structure in SweetHome3D
Important: SweetHome3D files end in zip. After download, don't extract - just change filename to remove the .zip at the end and the .sh3d file will be openable in SweetHome3D. These can be upgraded in FreeCAD, the Sweet Home is a start.
- You can view sh3d files online by downloading the file, and uploading to http://www.sweethome3d.com/SweetHome3DOnlineManager.jsp. This is the floor, apparently using WebGL :
- You can download SweetHome3D and view on your computer - http://www.sweethome3d.com/download.jsp
Note: Embedding of sh3d files doesn't work. There is an embedding capacity provided by SH3D online on their servers, but it can't be iframed into existing webpages.
