Wishlist: IFC as Project file It would be nice If I could Import, modify and save an IFC File. It seems FreeCAD with Version 1 now does support Native IFC. It would be cool to have Sweet Home for staging an IFC file. |

Re: Wishlist: IFC as Project file Use FreeCAD to export to .OBJ or .DAE which you can import in Sweet Home 3D. ---------------------------------------- Dodecagon.nl 1300+ 3D models, manuals, and projects |

Re: Wishlist: IFC as Project file Thanks for the feedback. I know about the Workaround. |

Re: Wishlist: IFC as Project file For the record. As far, It is not possible to import an .obj or a .dae as Building . It could only been imported as Furniture. I tested it again. May I misunderstood something? |

Re: Wishlist: IFC as Project file For the record. As far, It is not possible to import an .obj or a .dae as Building . It could only been imported as Furniture. I tested it again. May I misunderstood something? Any 3D model format, including OBJ and DAE, represents a single 3D model. Usually a 3D model is a piece of furniture or object. It can represent a complete building but it will be a single object. Only the Sweet Home 3D .sh3d format represents a building where you can manipulate the parts as they are defined, i.e. walls, rooms, furniture, etc. So yes, you can import a complete building but it will be like it is furniture where you can change the colors/textures of the materials but not change the dimensions of the individual parts in the model.To some extend you can split the parts but you will not get walls or rooms as defined in Sweet Home 3D, only as pieces of furniture. ---------------------------------------- Dodecagon.nl 1300+ 3D models, manuals, and projects |

Re: Wishlist: IFC as Project file If I import a Building into sh3d it would not be a problem that I could not modify the walls. That would be an extra feature. The Problem is more that the drawing is not working. As far, if I import a building, I'm not able to select a surface and say it is the ground for floor 1 or floor 2. |

Re: Wishlist: IFC as Project file The Problem is more that the drawing is not working. As far, if I import a building, I'm not able to select a surface and say it is the ground for floor 1 or floor 2. It's a model, just like for example a chair or cabinet only now it represents a building. You can do not more or less with that model as you can do with a model of a chair or cabinet. Don't expect any more from a model. Sweet Home 3D is a house and interior design spplication, not a 3D modelling program. If you want to modify something in the model itself you need something like Blender or another 3D modelling application. Generally it's rather useless to import a complete building.---------------------------------------- Dodecagon.nl 1300+ 3D models, manuals, and projects |

Re: Wishlist: IFC as Project file No I do not assume that a IFC Building could be modified inside sh3d. But I assume to see at least the plan above. And be able to select the ground and place furniture. A big plus would be I f I could save the IFC with the interior design I did add with sh3d. |

Re: Wishlist: IFC as Project file If you want to work with IFC, use Blender and the Bonsai addon. It adds native IFC to Blender. I've moved away from SH3D because for my purposes Bonsai works better for me. The only caveat is that it is still a work-in-progress, so it can be tough to get to grips with. Trying to add IFC to SH3D would be like mixing oil and water - they do things in very different ways. |

Re: Wishlist: IFC as Project file Sorry sjb007, but IFC and SH3D data organization are quite similar from tests made in the past: both include notions of levels, walls, windows, objects,... It's just there would be a lot of work to program IFC support in Sweet Home 3D. ---------------------------------------- Emmanuel Puybaret, Sweet Home 3D creator |

Re: Wishlist: IFC as Project file Maybe I overstated there a little. Sure, SH3D and IFC have levels, walls, doors and windows - so do a lot of applications. But working with IFC (not just a one way import) means you have to handle a lot of stuff that SH3D doesn't currently understand. If not you lose tons of information on the other side of SH3D. Just one "different way" of working - Defining a gable end wall: In SH3D create a wall, split it in two, then set the start/end heights of both walls to the necessary heights. In Bonsai create a single wall as tall as the peak, define two half space planes, and use them to cut away both slopes. (This method by the way is much easier to create accurate internal walls in lofts, because I cut them to the roof slope, instead of having to calculate the correct end heights.) As far as I'm aware so far, IFC has no concept of wall start/end heights, and SH3D has no concept of half space planes. In addition I can also use those planes to cut a wall at the bottom, create an overhanging wall end, or cut a slope front-back instead of side-side. I can also create arbitrary void shapes and use them to cut all kinds of strange shapes out of the wall (or slab, or roof, etc). I used that to cut flared window reveals in my walls for example. Would it be possible to translate that into SH3D wall parts? I don't think so, not unless SH3D walls are significantly changed so they can handle all IFC features. You could maybe create dumb objects instead, but then they wouldn't be walls with the features of native SH3D walls. Which is all a bit immaterial, because as you state, it would be a lot of work. I have no idea what Space Mushroom's plans are, but I suspect IFC support isn't in there. So to reiterate... if the OP wants to work with IFC, use something that understands IFC. |

Re: Wishlist: IFC as Project file Thank you all for your insight here. First of all, I am not interested in editing IFC data. It's about staging rooms. As a user, I don't dare to predict how the goal of using IFC for this purpose can be meaningfully achieved. But if it is that difficult, then you can also start small and only consider the import a stupid body as a house. The important thing is that in the end it is clear where the floors are and where the walls are. Then you can stage with it. It does not have to be perfect, it should be possible. Offering native IFC editing like FreeCAD does in 1.0 can be omitted and perhaps declared as a distant goal. |
