There's tooling to calculate area and volume (or extract it from the explicit IfcPropertySet definitions associated to elements) and you can traverse the associated materials.

Their SDKs are not freely available. Luckily, the conversion for IFC to Collada using IfcConvert [1] provides the same or better results and allows much more configuration options. Importing Collada (DAE) into 3ds max seems to work seemlessly as well. In case you favour a graphical user interface over a command line executable there is a user-contributed graphical front-end for IfcConvert available here [2]. Hope that helps, kind regards, Thomas<br /><br />[1] http://ifcopenshell.org/ifcconvert.html<br />[2] https://sourceforge.net/p/ifcopenshell/discussion/1782717/thread/55558229/#2435thomashttps://www.blogger.com/profile/02091082558478878837noreply@blogger.comtag:blogger.com,1999:blog-1792504135258878475.post-8446925267423001372017-09-18T02:23:08.230+02:002017-09-18T02:23:08.230+02:00Hi, just wandering if "IfcOpenShell 0.5.0 pre...Hi, just wandering if "IfcOpenShell 0.5.0 preview 2" will be released for "3ds Max 2014 64bit" any time soon?UA-RMhttps://www.blogger.com/profile/12610669215574426335noreply@blogger.comtag:blogger.com,1999:blog-1792504135258878475.post-24831016198081100982017-04-06T23:19:19.318+02:002017-04-06T23:19:19.318+02:00Thank you^^Thank you^^1D_Inchttps://www.blogger.com/profile/08177140223857784283noreply@blogger.comtag:blogger.com,1999:blog-1792504135258878475.post-7306756227187564772017-02-23T16:52:57.797+01:002017-02-23T16:52:57.797+01:00Thank you for your continued support.

I would be reluctant to introduce this situation again.<br /><br />At the same time I do understand the need for more lightweight IFC workflows, both in terms of writing as well as reading and analysis. I would also advise to also take part in the discussions on the FreeCAD forum and see whether where that is heading suits your need: http://forum.freecadweb.org/viewtopic.php?f=23&t=7222 I have understood the upcoming FreeCAD 0.15 release will feature many improvements in IFC importing and exporting.

Which in itself is very cool, one can never have too many parenthesis! But a lot of information that is necessary to constitute a valid and meaningful IFC file simply has no place in a geometrical mesh-based application such as Blender. Apart from all the attributes, also consider the material layer set of a wall for example. Also, the hierarchical nature of IFC [to have a Project > Site > Building > Storey and Windows parented to Openings parented to Walls] would impose a high burden on the modeller, but is necessary for BIM authoring tools like Revit to make sense of the exported file.<br /><br />Have you tried importing your meshes into FreeCAD and export IFC from there?<br /><br />Kind regards,<br />Thomasthomashttps://www.blogger.com/profile/02091082558478878837noreply@blogger.comtag:blogger.com,1999:blog-1792504135258878475.post-13390129323867990722015-03-01T01:07:49.681+01:002015-03-01T01:07:49.681+01:00Awww, update!

Blender by now is many versions ahead and because they moved to Python 3.4, the addon is no longer compatible. But in addition, IfcOpenShell has many improvements to its code base, which users, who do not compile themselves, currently do not benefit from. A new release is very high on my list.<br /><br />Kind regards,<br />Thomasthomashttps://www.blogger.com/profile/02091082558478878837noreply@blogger.com
