Using SweetHome3D

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.

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.

First Floor Interior

HintLightbulb.png Hint: The first floor exterior walls sit on the sill so the interior walls start 1.5" lower. These panels have been designed to use 106.125" studs (1.5" longer than standard pre-cut studs) so they will be the same height as the exterior walls when they are in place. The utility channel spacers are also raised 1.5" to be at the same height as in the exterior walls

  1. Please download SweetHome3D to view this file - https://drive.google.com/file/d/1X7H-kKLtFZrs0y3Qwq7GYdgxnL4wskm5/view?usp=sharing
  2. Determine the correct stair height, and then the landing is like in this concept model - https://drive.google.com/file/d/1X4dHvEETeuBPjB34wXJ-mqc97YHgaWai/view
  3. Then do the staircase in FreeCAD, which I started here - https://wiki.opensourceecology.org/wiki/Seed_Home_v2_3D_CAD#Technical_Modules

Plumbing Rough-In

Note: due to local variations - the actual CAD must reconcile against materials used ([27]) and the data collection from annotated PVC pictures at [28]. This is proper CAD-BOM-Reality reconciliation required for a full digital model.

This doc is in preparation for generating accurate CAD. By thinking out the logic of the system carefully, we optimize for build efficiency and thus degenerate to a sound design, which is then CADded up.
