I didn t get familiar with the saving process so i ll follow the first approach for my mvp.
Sweet home 3d plugins roof.
An example of roof elements that can be put together to create different roofs the pictures demonstrate how they can be put together.
Under linux if it doesn t work install it with the terminalcommand path to sweethome3dpath to plugin sh3por copy the sh3p file in the subfolder eteks sweethome3d pluginsof your user folder.
One of my main goals is to store the roof model the gabels and the properties so you can recalculate the roof after adding some jutty so it would survive to be opened and saved again by a blank sh3d no plugins.
Return to the free 3d models page.
A plug in proposes additionnal features in sweet home 3d and can be installed by double clicking on its sh3p file.
The same can be done and more exactly following the instructions in the guides search forum and documentation.
The creator of each 3d model is indicated when you place the mouse pointer on its image.
