SH3D and IFC

[jtm2020hyo]

hello, I am new.

I found a 2016 post and I am curious about this new feature.

http://www.sweethome3d.com/support/foru ... hread,6794

@robin87105 said that he will try to create an IFC import-export plug-in and I found this another link:

https://sourceforge.net/projects/sweethome3dbimplugin/

... then, is an IFC plug-in being created?

The project Sweet Home 3D BIM Plugin hosted on SourceForge.net doesn't seem to have gone very far.

A few years ago, I worked on IFC format support for Sweet Home 3D with the help of another developer, but the plug-in still needs some refinements before being published. It's not so motivating because there aren't so often requests about this feature. My feeling is IFC / BIM world doesn't seem to match the target of Sweet Home 3D. The few IFC examples we could find at that moment were rare and generally reproduced big buildings. Not really the same thing as Sweet Home 3D, where you can find many examples (probably because it's open source), reproducing not very large homes. But maybe this changed during the past years...

IFC is relevant these days, with IFC you can create a workflow with Revit, AutoCAD Architecture and FreeCAD, if you check in the freeCAD forums, they are trying to create an import-export SH3D format, but they are requesting for help.

now that MASSIS is another great BIM software, we need IFC import-export so bad.

I want to help, I have some IFC samples let me know where can I sent.

I just have a question, why finish a html5 export instead IFC import export plugin? Is html5 easier or superior to IFC?

My feeling is IFC / BIM world doesn't seem to match the target of Sweet Home 3D...

You might check old autodesk dragonfly, revit formit or sketchup files for inspiration, sh3d is considerated a predesign program and that mean that already can be considerate as part of a bim workflow

[...] they are trying to create an import-export SH3D format, but they are requesting for help.

I would suggest to look at the DTD of Sweet Home 3D at http://www.sweethome3d.com/SweetHome3D.dtd or in HomeXMLHandler Javadoc.
The file format is quite simple: a SH3D file is a zip file containing a [font=courier new]Home.xml[/font] entry respecting that DTD and entries for images and 3D models referenced by [font=courier new]icon[/font], [font=courier new]planIcon[/font], [font=courier new]model[/font] and [font=courier new]image[/font] attributes. The data structure is quite similar to IFC as far as I remember.

why finish a html5 export instead IFC import export plugin?

Even if it's a big task, I prefer to finish HTML5 support for Sweet Home 3D because applets for its Online version and Viewer are dying from the lack of support of the Java plugin in browsers and they need a replacing solution.
Support for IFC is a new feature so, as long as it isn't published, maintaining it isn't required yet. Keep also in mind that Sweet Home 3D is a program for a general audience, therefore supporting IFC in Sweet Home 3D is probably not the first thing expected by this public.

If you have some IFC files you can share, please send them to me or share them wherever you want.

Just want to say that I'm interested in IFC support in SH3D aswell.

[stgaup]

Please add this feature!

*8022 IFC files, including furniture than might be added to SH3D, here:

* bimvision example IFC models, "only for viewing, not for commercial use":

* 54 IFC commercial objects:

* 21 IFC objects mark haulotte:

... well for now I just have this, I hope I can do my own IFC since SH3D soon.

Do you guys know https://3dwarehouse.sketchup.com? No need for IFC support in my opinion...

...yes SketchUp and DragonFly probably are the best competitors for SH3D, but SH3D can create fastest drawings, and if they add a direct integration with PyFlow being both open sources, similar to Revit with Dynamo, could be more powerful and fastest than SketchUp.

...for another part, MASSIS, than was based on SH3D, could import IFC to their BIM projects, and this is just starting.
