User projects and use-cases of BIMserver and spin-offs.

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.

“Not a 0.1 anymore”

About a week ago the first public release of the bimserver came online. Version 0.1, release candidate 1. We still had some known issues, but wanted to know if there were some ‘unknown’ issues. You helped us a lot by testing the first version and by giving us your feedback. The best feedback we had was lot of people saying that this is not a 0.1 version but more like a 1.0. We have some wild ideas for the 1.0 version, so for the time being we stick to the 0.1.

Thanks to your help in testing, we have done some development and publish the second release candidate today. You can download it on We’ve fixed the know issues, and added some new features. You can see the changes in the changelog.  The best new feature (we think) is that the standalone BIMserver jarfile now has a simple UI that makes starting/stopping the server easier.

What we also did was pushing 3Gb of IFC files into the server, and pulling it out again.  Just to test the reading, writing mechanism. Some new bugs came up, but we fixed them immediately. Thanks to that we now have some cool error messages when the server gets a corrupt IFC file. You can see an example on this link (generated from the almost 1600 IFC files we have used during the test).

Let’s hope the feedback will be just as good this time so we can have a official 0.1 version in this month.
