MEP models need more data than your usual architectural model. The reason is that you need to make a lot of calculations with them, and… Read More »Ports in IFC – Connecting the dots

If you are familiar with Revit you have an idea what object types are. They define the common behavior (geometry and property logic) of all… Read More »Typing – the efficiency booster

Well, this might seem a bit strange. Also, not sure if privacy rules allow this in your country or project. But it’s about the possibilities… Read More »List of project participants in IFC

Properties – the “I” in BIM – should be quite simple, right? Give it a name, and assign a value. That’s at least as many… Read More »Property types in IFC

Object placement is another flexible concept in #IFC. Most #BIM programs only support one type of placement, which normally is local placement (XYZ coordinates relative… Read More »Where are my elements?

Openings are one the most complex elements when coordinating designs between architects, structural engineers, MEP engineers and construction companies (one would not believe that). So… Read More »Openings in openBIM

One of the most underestimated features of IFC – and I believe there are many of them – is how geometries are treated. Many BIM… Read More »Geometries in IFC – from zero to many

IFC is static? Far from it! Let me introduce the IfcParameterizedProfileDef: a class that lets you describe basic profile geometry just by a few attributes.… Read More »Parametric geometry in IFC

The logic of property sets in #IFC is that they are added as a package to a certain class or type. If you add them… Read More »How to structure your object properties

Property and quantity sets work a bit differently in IFC than in other BIM programs (by now you should be used to this, right?). And… Read More »Property set and quantity set assignment
