Free STL viewer from Materialise

The Belgian firm Materialise, specializing in consultancy, services and development for rapid prototyping has released a free tool for inspection and conversion of STL files, based on their flagship Magics software. It's called Minimagics and is available for Windows.

You can use it to inspect STL files and to optimize their format. The actual tools to correct errors and optimize the geometry are only available in their (expensive) commercial tools.

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 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: ...

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 po...
