IFC Export of Migrated/Linked Projects from ARCHICAD 21

Forward migration is usually relatively smooth with ARCHICAD nowadays, but if it’s paired with some hotlinking and IFC export then the new features might cause some confusion.
Two of the latest additions to ARCHICAD are the introduction of Classification Systems and the improved IFC Translator settings, which both provide a lot of opportunities and smart management functions for the user, but during migration+hotlinking+IFC export they will need some extra cautiousness, otherwise the user might get unexpected results. Even though this might not be a mainstream case, we just had a few support issues in Singapore because of this, so let me give a generic explanation, hoping to clear up the confusion as much as possible 🙂

Creating Contour Lines of Meshes without Ridges

ARCHICAD Meshes can be created in many different ways – by creating level ridges based on external drawings, by importing point clouds and modeling the terrain based on it or importing text files with the coordinates and the let ARCHICAD automatically build the terrain.
The first scenario is ideal as it will provide us with the contours that mark points at the same elevation, but other creation methods do not provide that natively. Using add-ons with more comprehensive earthwork-related functions can be an option, but for such a simple request we also have a solution within ARCHICAD.

Labeling IDs of Surfaces and Building Materials

I recently found a post on LinkedIn discussing the possibilities of labeling an abbreviation (ID or code) of elements, mainly the Surfaces. Since there is no perfect solution, two main ideas emerged other than using external label objects: use Labels along with Properties or IFC mapping. Though the first may seem to be easy to set up with ARCHICAD 20, it has its risks when it comes to change management since the Properties are not tied to other attributes that may change (for example Composite or Surface) unless you ALWAYS use Favorites, so let’s have a look at the Label tool options and the attributes instead.

Grasshopper-ARCHICAD Live Connection for MAC Test Run

The MAC version of the Grasshopper-ARCHICAD Live Connection has been released recently, so it was high time doing a test run on this platform as well. The following is not focusing on the performance and the features, the pure intention is to give some guidance to those who also prefer MAC in general and had no access to Rhino and Grasshopper because of that.

Well, the bad news is that officially Grasshopper is still not available for MAC yet, but there is a way to test all these three applications – even if it is not a straightforward way. Let’s see the ingredients.

Data Safety, File Recovery and Troubleshooting

ARCHICAD usually got you covered by sophisticated solutions in case of a crash, apparent data loss or file damage, but sometimes manual recovery or troubleshooting might be needed. The following post collects the backup and recovery options and the location of those logs and folders that should be sent as part of support queries regarding Teamwork issues.
