Second candidate for the 1.0 release

Some users found a few bugs in the first release candidate for version 1.0 of the open source BIMserver software. We fixed these issues and also did some additional work on the ‘intelligent merging’. You can test this new merging feature by selecting ‘intelligent merging’ in the settings screen. The merged models (project with subprojects) are now better merged than before. Feel free to try this version and send us feedback. Download it from

First Release Candidate 1.0

Today we released the first candidate for the 1.0 release of the open source BIMserver software. As you know a lot has changed since the 0.8.1. We made a huge leap in speed, performance and stability again. Under the hood the IFC Engine Library has fixed a caching bug. This makes the export to non-IFC formats (Google Earth, KML, CityGML, Collada) much more stable. Most important new feature is the clash detection. There are still a few issues that we would like to resolve before the 1.0 stable release, but think you should have a look at this stage. Feel free to try this version and send us feedback.

Integration of BIM and DMS/Workflow

DMS and Workflow for BIMserverThe development team always gets a lot of questions like ‘can I link pdfs to IFC objects?’ or ‘is there a way to create a workflow in the BIMserver?’ We strongly believe that the open source BIMserver is a BIMserver in its core and should stay that way. We kindly reject all feature requests about Document Management and Workflow. We just do what we are good at: IFC and BIM. However, the SOAP interface of the BIMserver has been around since release 0.1 and was always indented for other applications to interface with the BIMserver and its IFC data. During the BIMserver breakfast there were two Birds of a Feather presentations that both showed applications interacting with the BIMserver software using SOAP. One of them was a ‘send to server’ and ‘get from server’ button in Revit. This way a user doesn’t have to export nor import an IFC model and upload/download it from the server manually. The button in Revit does this automatically. This was developed by ICN solutions.

Another presentation showed the progress of an Alfresco plug-in to interact with BIMserver data. Alfresco is an open source Document Management System (DMS) that is very professional. An agile company from Amsterdam called Perfect Blue has created the plug-in. Features of this plug-in are: linking documents (like pdf) to specific IFC objects, latest IFC objects, BIMserver projects or revisions. The plug-in also enables the Alfresco workflow module to interact with your BIMserver. This is a great way of using workflow for BIM. By using the plug-in the user completely uses the Alfresco graphical user interface. The BIMserver GUI is (for obvious reasons) ignored. Feel free to have a look at (in Dutch) for more information. The site doesn’t state the license of the plug-in, but because the developers are open source fans, we trust that it will be free and open source.

Finished breakfast

The BIMserver Breakfast yesterday in Utrecht (the Netherlands) was a big success. Site statistics showed that 183 unique visitors were at the website. 121 of them did that from the venue site in Utrecht. Looking at the map of Google analytics, Utrecht seemed to be the center of the BIMserver-world yesterday. Every attendant had a lot of questions that were answered by the experts from TNO. You can find a photo-impression at this link. The breakfast site will stay available for the rest of the year. A professional video was also recorded during this day. The video will be available as soon as possible. Again thank you very much to our sponsors TNO and BNA and of course to all the attendants.
