Using Yorik's SweetHome3D importer

[Manticore]

Should be mentioned that:
1) You need the 'Export to HTML5' plugin for Sweethome3D.
2) This produces a zip file <Building name>.zip. This file will not work. it contains (among other things) a file also called <Building name>.zip. This is the one you need.

Welcome to the forum! Thanks for your comments!

I'm not familiar with that plugin, but I guess that 1) needs to go into our wiki documentation and 2) is a bug (zip in zip)?

The plugin was only released on May 5th, so it's still in early stages.

Wow you're fast!

Yes, it's still very early, and I'm discussing with the sweethome3d people, so there might still be changes (on their side too), so I didn't want to advertise something that could change afterwards.

But since we are there now...

- you need sweethome3d >= 5.2
- you need the OBJ/XML plugin from http://www.sweethome3d.com/plugins/Expo ... J-1.1.sh3p

Otherwise the zip produced will not contain the walls as XML. With this plugin, there is only one zip produced, not a zip in a zip.

The walls get imported reasonably well, but there are some problems because in sweethome3d it is hard to make endpoint coincidents. So walls often import with bad geometry. This is often solved by editing the sketch that is the baseline of walls, and add a "point-to-point" constraint on coincident points.

The geometry of windows get turned into shapes, which can produce some crappy invalid shapes.

The furniture works well already, but they are still meshes, not sure yet about what to do with them next.

I've had trouble importing SweetHome3D exports into FreeCAD. In SweetHome 3D, the original file has four levels, four feet apart vertically (it's a split level house).
Exporting from SweetHome3D via Tools | HTML5 and importing as SweetHome3D .zip file yields nothing.
Exporting via Tools | XML/OBJ and importing as SweetHome3D .zip file yields all levels at the same elevation, and horizontally misplaced windows and doors.

Later, I updated the SweetHome3D Export XML/OBJ plugin to 1.3, with results identical to the original 1.1 plugin. ( I got it from here: www.sweethome3d.com/plugins/ExportToXMLOBJ-1.3.sh3p)

Just wanted to report that I tried the export/import procedure from sh3d to freecad and experienced some problems.
Most things seems to have been mirrored, and the wall, door and window elements are not placed correctly. The shades seems to not have been mirrored.

Made some more observations,

After messing around a bit in the document tree, I got some sub shapes of doors and windows visible in almost the right position:

sh3d import fc1.png (228.39 KiB) Viewed 3015 times

But it seems like all objects are anchored to the "ground plane":

sh3d import fc2.png (328.41 KiB) Viewed 3015 times

Also some of the wall lines are a bit off:

sh3d import fc3.png (234.46 KiB) Viewed 3015 times

Nice!
I'll notate issue #2584
Can we use git to track/merge your changes so far?

Very interesting.
