Every now and then the question arises: how to use ARCHICAD as a coordination tool. There are multiple workflows in which you can differentiate and compare the models of different disciplines. Let’s take a look at the following model where architecture was created using ARCHICAD, structure using Tekla Structures and MEP using Revit MEP.
Recently came across an issue with door swings when IFC file is exported from Revit 2019 (19.2.10.7). The doors get mirrored when imported into ARCHICAD or Solibri. This is a big concern as the submission drawings were produced with swing direction against the exit direction. This was due to missing information in Revit. The Door family should have the Operation parameter defined and there is also a specific way to indicate the door swing with lines.
Decided to re-visit coordinate settings for projects that requires IFC exchange between ARCHICAD and Revit in this blog. In my previous blogs the focus was only on Latitude(Lat) and Longitude(Long). I received some requests to handle Northing and Easting (UTM) as well. To address that I tested the settings of both ARCHICAD and Revit and share the result via this blog.
Before going into how to do the settings we need to understand how both tools work and various coordinate systems available for us to use.
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 🙂
Recently came accross a situation where the Design Architect need to exchange ARCHICAD model with their project partners. The Main Contractor was using REVIT for their BIM process. So, there was a need for conversion of ARCHICAD model to REVIT model via IFC.
The project has large topography as it was a infrastructure project and all of them were created using Mesh object in ARCHICAD. When the topography was transferred to REVIT via IFC that becomes as a Model In-Place element which can not be edited easily. The Main Contractor requested for Toposurface which can be edited further in REVIT. This article covers the solution on how to re-create an editable Toposurface in REVIT using the data exported from ARCHICAD.
This post is a follow-up of previous post Project Base Files for Coordination. In case the Structural team decided to use Tekla Structures for their BIM authoring then they need a Project Base File in Tekla with setup based on Architectural file.
Setup the Architectural Project Base File in ARCHICAD and export as IFC file as discussed in the post Project Base Files for Coordination.
