Online demo of bimserver

Finally its there! For those who do not have the right admin-permission (or just do not have the patience) to install the open source bimserver on their own pc, we have installed it on one of our own servers. This ‘demoserver‘ on gives you he possibility to test the very latest version of the bimserver. This version even has more features than the latest stable release. Some new features at a glance:

  • Download the model (or parts of the model) as ifcXML;
  • The query functions are easier to find;
  • Query parts of the model using the IFC GUID (we know some of you were waiting for this!)

This version also has multiuser behavior (kind of for a necessary feature for an online server). You can also find all this new stuff in the latest version of the sourcecode. All these features are not tested very well (and that is why they are not in the stable release). We kind of hope you guys will help test them by using this demoserver.
So please help us find issues, feed us with feature-requests and userfeedback. Want to start right away? Go to and use the ‘register’ button to open an account.

Update: The demo server is offline. Since the 1.2 version does not have an end-user GUI anymore, there is no demo available for end users.

New LinkedIn group (and other ways to keep track)

It might be hard to keep track of all the info surrounding this project. When you want to learn more about this open source project, there are several ways to do so. As every open source project this one also has mailinglists. This is probably the best and fastest way to get an answer on your questions. So please subscribe to one or more of the lists and fire your questions to the community. Please pay attention: you have to be subscribed to the list to post something.

Then there is the wiki:
As a good wiki should, the documentation is growing. Please feel free to help us fill the wiki! Some basic documentation (the most popular) can be found on the website:

When you find a bug, please report it by using the bugtracker and of course the featurerequest.
Bimserver is under the GPL license. That means you can get the whole sourcecode and build the program yourself. The sourcecode is hosted on in our own subversion repository. You can browse the sourcecode with your favorite webbrowser directly on the source repository. Use anonymous as the username and you míght have to user anonymous as password to log in.
A new way to keep track of what’s happening is the possibility to join the new LinkedIn group.
And when everything fails you can always e-mail or skype us.

Update: the linkedin group is deprecated.

First stable release

About two weeks ago the second release candidate of the bimserver came online. After two weeks of intense testing (by ourselves and by you, the users) we did not find any new bugs. That is why we think it is time to release the first stable version of the bimserver: 0.1.

You can download the builds on

When you have some new ideas or feature requests, please let us know so we might implement them in the next release.

We hope to also have a demoserver online in the beginning of next week. The demoserver can be used to play around with the bimserver without having to download and install it.

Update: the downloads are now on
