BIMserver software used in Dutch BIMCaseWeek

bimcaseweekThe software is used this week in the Dutch BIMCaseweek. The week (which only lasts for 4 days) started today. Two teams use the BIMserver software. TNO has provided a cloudserver with 16 Gb internal RAM memory to handle the big models. The teams use the BIMserver software for backup, revision management and of course the merging. One of the users said “I can not find any software that can merge the different models for construction, electrician, HVAC, et cetera… The BIMserver software is the only one that does the job“. The proof that the bimserver software can do the job,  can be found in the picture.

This is a big test for the software and we are very happy that the teams trust and like the software enough to use it in this competition.

In between two releases…..

As you guys know, we just released the 0.8.1 version. For the 0.9 release the main attraction will be the integrated clash detection. Also other features will be very useful for the next release.
However, the development team decided that this is the time to look at the core again. After every release we checked back to the core and looked how the new features and new direction of the development influences the core. Also after the latest release we checked back under the hood to see what can be better.
These are the hours of work nobody really sees because it’s not a new button or feature, but just some milliseconds of performance or better memory use. However, we think it is the base of the BIMserver and spend a lot of time on this.

We know that most users will probably see something else then just some blabbering about memory use, stacksize and heapsize. So this is the time to give you something…. During the base improvement of the core, we also had a closer look at the O3D feature. And there is some good news: it works! And we have a picture for the fans.
For the developers: the code is in the SVN repository. For the mainstream users: just let us look at the stacksize and heapsize and wait patient. The next release will have the cool stuff. goes conferences

The open source BIMserver seeks publicity in the Netherlands next week. Most of our users are outside of the Netherlands, while most of the development is done by Dutch guys. That is why we get away from our computerscreens and try to connect to real people next week (of course accompanied by coffee). We will be at the Bouw&ICT beurs and ICTDelta.

Hope to see you there!

New Release: v0.8.1 0.8.1 usability release.

The open source BIMserver just released a new stable version of the software. The new release is the 0.8.1 version. This release should be a ‘usability update’ so the interface will be (even)  more user friendly. However, during development we decided to integrate some major changes in the core of the architecture. The IFC Engine DLL is now running in a separate JVM. When the DLL crashes, the BIMserver keeps on running and can even startup the crashed JVM again. This makes the use of the software more stable.

Just some of the changes:

  • Fixed bugs (sourceforge buglist)
  • ‘work in progress’ button on compare and download.
  • ‘e-mail this’ button on compare.
  • Compare function out of revision lists.
  • ‘Upload in progress’ feature.
  • ‘no revisions yet’ notice at empty projects.
  • Anonymous access (checkbox) at creation of projects.
  • CityGML bugs fixed.
  • ifcXML 100% valid.
  • IFC Engine DLL loading and installation is integrated.
  • IFC schema to IFC Engine DLL optimised.
  • Separate notice of active and archived checkouts.
  • Registration of new users optional by ‘only admin’ or ‘register from start’.
  • Created separat JVMs for IFC Engine DLL and BIMserver.
  • Created a settings page for the administrator (to edit settings.xml in the webinterface).
  • Split upload of IFC and handling IFC data into database (performance).
  • Changed SOAP Url to /bimserver/services/soap
  • Upload IFC in ZIP files.
  • Download models in ZIP files.
  • Ignoring identical upload of revisions.
  • Merging subprojects of choice by user.
  • Non-usefull tabs are hiding in the webinterface.
  • Update of Jetty (in standalone release)
  • Created info page for IFC ojects (to embed)
  • Added ‘plain text’ option for download.
  • Upload/download ignore.xml file in settings page.
  • Added IFC browser for projects and revisions (integrated with summary page)
  • Added ‘forgot password?’ link on login page.
  • RSS feeds work with autorisation.
  • Checking if upload file is IFC.
  • Checking (on startup) if database is not locked by other proces (other BIMserver instance)
  • Checking (on startup) for correct database schema.
  • and a lot more….

The team doesn’t stop developing and new plans are already being deployed.
The latest release is now available for download at The demoserver is also running the stable version. Check it out on
