what information is it that you would like saved in XML format? structural element beams & columns & walls and slabs.

Thanks, Mohamed.

Do you really mean XML, or do you mean IFC?

If XML, post an example of how you want something encoded. You realize that XML is simply a file format and that there are infinite possibilities for an XML encoding of a beam, for example, right?

Cheers,

please find the attached sample of xml file which i need to export from ArchiCad.

As I said, XML is simply a file format ... like saying "text". So, it is impossible for any software to produce a desired XML file out of the box unless it is programmed specifically to do that...usually by the manufacturer of the product that wants that particular XML format.

As far as I know, the only XML model export that ArchiCAD supports directly is IFCXML.

In your case, your XML is for an XsteelModel system. You (if you are a programmer) or the company with which you are trying to communicate this data, can program a custom ArchiCAD plug-in (add-on) to create that XML file. (See the Developer Forum sticky announcements here for links.)

An alternative is to write or hire someone to write (depending on skills) a program to convert an IFCXML or other-archicad-exported file into the XML file that you want. This IFC to XsteelModel conversion would be a pain because IFC does not store coordinates next to elements (e.g., columns), but rather in a separate coordinate list that is referred to by name.

I think that the steel xml format that you show is used by Tekla? If so, Tekla accepts IFC, so the xml is not necessary.

GDL objects can read/write XML, but that does not help to get the general building model exported, as you want.

Hope this helps,
Karl

Karl's' right in these options ... to get xml out requires a bit of GDL. This can be done using a property object to create an XML output (write an xml file(write a text file which is given an XML extension))
The structure is not difficult and all you really need is an object which has the required parameters or properties which can be exported using the property object to write the output file. The advantage of using the property object is that it can be attached to any number of graphical object to create a consistent output format.
