Free software for automatic IFC clash-detection

As some of you might know the Netherlands organisation for applied scientific research TNO is one of the organisations behind the development of this open source bimserver. They are also the developers of the fastest IFC render engine in the world: the IFC engine series.

But the innovation doesn’t stop… Today a press release will be send to announce the ‘first free automatic IFC clash detection tool’. The good news for BIMserver.org is that the automatic clash detection only works on models that are fetched from a BIMserver!

The clash detection tool has a ‘open from server’ button that enables you to (after login) select a project and a specific revision. The IFC model is than downloaded from the server and checked for clashes. You can even view each clash in the viewer and zoom to it to evaluate. Have a look at the screenshots or the video to get an impression.

The clash detection function is embedded in the latest IFC Engine viewer. It’s still in beta so the TNO guys might update regularly.

Check out their website to download the latest version.

As i mentioned before, this tool is still in beta. When you have found a bug or want to give a suggestion (or other ways of feedback like compliments about his his excellent English in the movie below) feel free to e-mail the lead developer at pim.vandenhelm@tno.nl.

 

 

 

Come see BIMserver at FOSS4G conference

In October this year the next FOSS4G conference will be organized in Sydney. The community behind the open source BIMserver has provided two abstracts for presentations. Both abstracts are about the next generation implementation of the BIMserver features. Because the topic of FOSS4G is geographic information systems (GIS) both abstracts we provided are about the link between BIM and GIS. Currently this is one of the important topics for the next generation of BIMserver software. When you like these topics you can vote for the abstracts. The abstracts with the most votes will be invited to give a presentation.

Voting can be done on this site http://2009.foss4g.org/presentations/ You have to register first, but don’t let that keep you! The abstracts are titled: “BIMserver.org: integrating BIM and GIS” and “CityGML extension for Building Information Modelling (BIM) and IFC”. The two paper-abstracts are the only one with the tag ‘bim’  so you can jump right to them by clicking here.

We hope that a presentation in Sydney will create enthusiastic developers for these specific features of the BIMserver or, even better, create a link between GeoserverDeegree and BIMserver.org.

Semantic Web for BIM

Today the thesis of Jakob Beetz came in our mailbox. As some of you might know Jakob is the most important contributor of the BIMserver.org architecture as we use it today.  His book, called “Facilitating distributed collaboration in the AEC/FM sector using Semantic Web Technologies”, gives a clear inside in the future of web based BIM modeling. BIMserver.org is very pleased with this clear statement of Semantic Web usage in the AEC sector. We like this see-through into the future of BIM and fully support the ideas behind it. The development team of BIMserver.org does a lot of research on Semantic Web for productmodelling in the AEC sector. The  Product Modelling Ontology (PMO) is one of the results of this research and development.

We expect that the work on PMO and the work Jakob did will joins forces in the next generation of BIMserver.org software. Thanks to Jakob’s work the future will become reality a bit faster!

Jakob will defend his thesis on June 29th at the University of Eindhoven (The Netherlands) and continue his work in this field for the comming years.

Clash detection

It’s been quiet for a while on this website. That’s because we’ve been working hard on new features of the bimserver.

Two big surprises are on the roll to be released very shortly. One of them is the new license model for the well known IFC Engine. As many of you might know the IFC Engine is known as the fastest IFC renderer in the world. It’s new license makes it easier to incorporate the IFC Engine DLL into the open source BIMserver. More on that in a few weeks, so just a little more patience.

The other surprise is the first ever free clash detection software for IFC. This new tool works smoothly with the open source BIMserver and detects clashes of objects in an IFC model. This free tool will be released as a private beta this week.

So please bare with us for just a few more days for some big steps in the development of IFC tools!
