Creating your Home Design with SweetHome3D

 Just a brief tutorial/tips, under construction, on how to get the best of your SH3D:

  • Break your space on different problems and create separate files to work on them. That way you can have different variations on the same file of the same space about that one problem and compare to each other. Eventually, when done, you can put it all together with the winning combination for every problem.
  • How to find more objects
  • How to go from your design in SHD3 to VR view, say on HTC Vive:
    • SH3D to do the plan
    • Then from there you can export the 3d view to .obj format
    • Use autodesk fbx to convert the obj to fbx
    • Use unity to import the fbx in htc vive scene. Use the unity toolkit as a start to have a simple teleport system.

3D models: formats, libraries, websites, translators

So, I am using SH3D (Sweet Home 3D). Really nice open source software that allows you to import objects. I am new to all these file formats, so, trying to figure what is the best source of objects and how to bring them in... Work in progress...

You can start by the SH3D library page. Remember to unzip the libraries before importing them, or else it will give you a message like everything was fine but actually nothing gets imported.

Working backwards, SH3D accepts (sorted for compatibility with Blender):
  • OBJ - Wavefront << This can be opened by blender
  • 3DS - 3D Studio << This can be opened by blender
  • DAE - DAE Collada << This can be opened by blender
  • LWS - LightWave Scene
  • KMZ: this is the Google Earth file format. Not sure what it is doing here...
  • ZIP
Nevertheless, the typical libraries websites:
Have files like (sorted by how easy is to get them in SH3D, mentioning what opens it that can translate it into one of the SH3D formats):
  • RFA: from Revit
  • DXF: use 3D Transform to transform STL, which Blender accepts.
  • FBX, from Filmbox, is proprietary (folks basically hack their way in, but with a newer version, they lose that...) although the newer versions seem that it can be opened in Blender.
  • DWG
  • STL 
  • SLDPRT: SolidWorks Part file. Proprietary. You can see it with Autodesk Viewer but don't know how to save it/translate it to something (without paying...).
  • SLDASM: SolidWorks too. It typically contains several of the above organized together...
  • MAX: From AutoDesk. Looks like there is no way.
In some cases we lose the texture, which is not cool...

Some of the files are more complex than what we want to use in SH3D, so, we need a way not only to open it but to edit it.

Websites that allow you to change formats for free:
  • http://www.greentoken.de/onlineconv/
    • Input formats: 3d, 3ds, fbx, ac, ac3d, acc, ase, ask, b3d, blend, bvh, cob, csm, dae, dxf, enff, hmp, ifc, irr, irrmesh, lwo, lws, lxo, md2, md3, md5anim, md5camera, md5mesh, mdc, mdl, mesh.xml, mot, ms3d, ndo, nff, obj, off, pk3, ply, prj, q3o, q3s, raw, scn, smd, stl, ter, uc, vta, x, xml, xgl
    • Export formats are: stl, stlb, collada, obj, 3ds, ply, json, x 
  • 3D Transform: takes .igs .iges .stp .step .brep .3ds .ase .dxf .stla .stlb .stl .wrl .iv .obj .swv .gmod .iv and outputs .STL
Editors:
  • Blender:
  • Sketchup: looks like they may have some freebies... Unfortunately does not run in Linux so won't comment further.
Eventually, we will also need textures. Textures are relatively easier as any jpg will work, except for the tileability (how to tile them side by side seamlessly)

Covid rapid (24 hrs turnaround) test for travelers in Dallas

 Just a note here to write down what I did:

  1. I found 3 options (there may be more but just stopped there :)):
    1. DevLabBio: $150 next day results. They replied very fast to my email. You book a time online. Fill the form, including the payment, ahead of arriving to the place.
    2. CareNow. $150 on their normal clinics. $250 at the airport.
    3. RealTimeLab: $250 for 24hrs turnaround time
  2. For a list of testing sites in Texas click here  Wherever you decide to go, make sure it is in this list so that it is not a fake place (there are reports of some popping up).
  3. The points guy article.
I did #1 (at 3PM on Thursday for a flight departure at 8PM on Saturday, and arrival at 10AM Sunday). My backup was #2 at the airport if it failed.

Nothing to do with Covid testing but other stuff required by immigration:

Getting Internet while traveling in Spain

The link that brought me to the solution is this nice one
