From ArchiCAD to Revit using IFC (with video)

It's in Dutch so maybe not for everybody, but I recorded a few video-tutorials discussing how to get a model from ArchiCAD into Revit in a more or less editable form, so you can still do some things with it. Using IFC and Solibri to inspect the exported model and see what is indeed exported but missing upon import.

Inside Revit, we make a Schedule and notice that the room does not pick up the ArchiCAD Zone Height properly and the category needs special attention to get through.

Important lessons: some ArchiCAD model simplification can make life easier (e.g. a SEO between wall and roof resulted in the window being placed one floor below its opening). Not sure if going back and forth between ArchiCAD and Revit to finetune IFC export is feasible for many people, but we have to deal with the current intricacies of the IFC implementations as they are today.
FWIW, Revit 2013 was running inside Windows 8 in Parallels, whereas ArchiCAD 16 and Solibri Model Checker 8 were running natively in Mountain Lion. But Revit was very usable still. And Screenflow was recording all 2880x1800 pixels in full glory. That said, I had a crash and some long IFC loading sections have been edited out of the video.

  1. In my Archicad Model, the building has a slope(30Deg) roof . When I input IFC into Revit, all slope roof become flat and straight up over the roof. Does Solibri can correct this issue, or We need to manually correct in Revit?

  2. When I tested, the sloped ArchiCAD roofs were still sloped, but came in as "in-place" families, with no properties to read or schedule. Import improved when I removed Solid Element Operators (SEO) in ArchiCAD first. Import was also improved by converting multi-plane roofs into single-plane roofs and use the Crop to Roof option instead of a SEO when connecting with walls.

    Solibri can read the IFC, but cannot alter it in any way. So I advice you to optimize transfer first and then fill in the blanks manually inside Revit. That way, the model is more native. This is a bit more work, but you get a much more usable Revit model as a result. Of course, you need some experience (and licenses) for both applications, which might not be an option for most people.

Getting BIM data into Unity (Part 9 - using IfcConvert)

This is part 9 of a series of posts about getting BIM data into Unity. In this post, we’ll discuss the IfcConvert utility from the IfcOpenShell Open Source IFC Library to preprocess an IFC model for integration with Unity. This is (finally?) again a coding post, with some scripts which are shared to build upon. Conversion of IFC into Unity-friendly formats The strategy with this approach is that you preprocess the IFC-file into more manageable formats for Unity integration. Most Web-platforms do some sort of pre-processing anyway, so what you see in your browsers is almost never an IFC-file, but an optimised Mesh-based geometric representation. However, it wouldn’t be BIM-related if we’d limit ourselves to the geometry, so we will parse the model information as well, albeit using another, pre-processed file. IFC to Wavefront OBJ I used a test IFC-model and used the IfcConvert-utility converted it into OBJ en XML formats. The default way to use it is very simple:

Improve usage of BIM during early design phases

When I was collecting ideas for a book chapter on BIM (that seemed to never have emerged after that), I collected 10 ideas, which I believe still reflect good recommendations to improve the usage of BIM during the early design phases. These ideas are related to BIM software, but you can apply them in any flavor, as long as you can model with Building Elements, Spaces and have control over representation. Introduction This article gives an overview of several recommendations and tips, to better apply BIM applications and BIM methodologies, in the context of the early design phases. Many of these tips are applicable in any BIM application and they are based on experience gathered from teaching, researching and using BIM software. Sometimes they could help software developers to improve the workflow of their particular BIM implementation. Tip 1 : Gradually increase the amount of information In the early design phases, the architect makes assumptions and lays out the main design in

Getting BIM data into Unity (Part 8 - Strategies to tackle IFC)

This is part 8 of a series of posts about getting BIM data into Unity. In this post, we’ll discuss IFC as a transfer format towards Unity. As with the previous post, this is not a coding post, although hints and examples are provided. Open BIM and IFC Everybody who ever met me or heard me present on a conference or BIM-lecture will not be surprised to hear that I’m a strong believer in the Industry Foundation Classes (IFC), an open standard, with already two versions published as an ISO standard, being IFC2x2 and IFC4 (but surprisingly not IFC2x3 which is widely used). In the ideal world, this would be the format to use to transfer BIM data into another environment, such as Unity. So what are our options? Looking in the Unity Asset Store Assimp is a library which supports multiple formats, including IFC. https://assetstore.unity.com/packages/tools/modeling/trilib-unity-model-loader-package-91777   I did a few attempts, but alas without any success. It is possib
