New release of Tekla BIMsight

I was informed by people from Tekla (they did a Webinar preview on 16th of June) that the new version of Tekla BIMsight 1.2 will be released on June 21st. Here is a sneak peek. More info on http://www.teklabimsight.com soon.

BIMsight is a standalone and free application (windows-only) to load, compare and view BIM models. It is  focused on IFC documents, but can load DWG and DGN (from AutoCAD-compatible and MicroStation compatible) applications as well.

The highlights of the original release still stand (I discussed it earlier in this blog : Tekla Bimsight), but the new version adds some nice features:

  • red lining in 3D = making annotations to the model, to give feedback to the model owner;
  • re-locating the model, which I read as being able to position different models (from different files/programs) to be properly aligned;
  • improved management, through grouping and linking (multi-files?)
So far, my biggest gripe is that it is Windows-only, but I intend to use it for a project in which we will have students collaborate using BIM models (together with BIMserver.org for IFC sharing). I was trying to install it in a virtual windows, but I completely trashed this system and had to start all over again.

The software avoids the Desktop-style interface (no Ribbon, less dialogs, tabbed, web-like GUI). Not sure if that suits the target audience, though (architects, engineers, many of them familiar with Windows-based CAD software).

Performance inside a Virtual machine was not too well, but don't think I can blame Tekla for that. After all, loading several large IFC models simultaneously is not that trivial. While I like the fact you get a fair sight on what is in the model, the biggest problem I see is that you have to know quite well what you are doing to generate IFC's in a particular structure. Having large lists of "WallStandardCase" (all named identically) does not help you that much if you want to look for a particular one. This is something I also noticed in the BIMserver ModelBrowser.

Not sure if the original model or the IFC export or the IFC import is to blame here. But whenever models get large (and don't all architectural/building models have this tendency), there are countless objects with the same name and it becomes hard to keep track of which object is where. Luckily, you have a fully interactive 3D window here, which is a huge benefit.

The biggest comparable software I see, is Solibri Model Viewer, the free Java-based and cross-platform viewer for (single) IFC files. I assume Autodesk NavisWorks is another candidate, although I have never tried it.

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 0 - Introduction)

This post reflects on work that I carried out, elaborated during my guidance of a few Master thesis students, to better integrate BIM models into Unity. This will be a multi-part post. This makes each article a bit shorter to read, but allows more in-depth information overall. Hope you like it. Please comment with feedback and further improvements. Basic methodology Unity can import geometry from FBX and Collada (DAE) files primarily. There are a few other formats, but these are the preferred ones. When integrating CAD or BIM files into a realtime environment, you have to convert the geometry. During my Unity teaching and the writing of the book Unity for Architectural Visualization ( buy from Packt ), I’ve come up with a basic diagram explaining geometry exchange between CAD and BIM software and Unity. Throughout these posts, we’ll go more into detail. We start with ArchiCAD, but will tackle Revit in a follow-up post. Promised!

PythonOCC : Open Source interactive CAD shell (and how to run it on OSX)

What is PythonOCC? PythonOCC is an Open Source (LGPL) Python-wrapper for OpenCASCADE. So what is OpenCASCADE (OCC)? This is an advanced Open Source (custom license) modeling kernel, comparable to commercial engines, such as ACIS or Parasolid, which are used in quite some commercial CAD programs. When you want to develop CAD software, you could use OCC and write programs in C++. And why using Python? With this wrapper, you can create CAD and geometry scripts in Python, which is an interpreted Object-oriented scripting language. You can write almost "on-the-fly" and seriously reduce the implementation effort, by skipping the compiling-phase. You can even interact with a running program in the Python interpreter. Want to read more about this? The OpenCASCADE official website  (currently Linux and Windows are officially supported) The PythonOCC website/blog  (beware that the core of the actions happen in the development repositories). So far so good. Now the nasty, techn...
