Would be happy to know your view about separating the model and its data/information and join data/information to the model based on tasks/“information need” For instance, for AIM or FIM, companies will provide a highly detailed model (Reference Model) with “appropriate data/information for asset m…

The decoupling of the visual representation and the alphanumeric information in models can be done. We have realized an approach for facilities management , in just using data templates and data sheets within IFC. Another way is, to exchange product data separate from the visual representation of th…

@ReD_CoDE what you have described can already be done, and in fact is already done in Blender BIM. Geometry, BIM objects, and properties are completely decoupled.

maybe i’m missing some vital information, but what is the point in decoupling the alphanumeric data from the geometry model beside file size? i’ve always assumed that 5g would allow for any data size, let alone zipped ifc or bcf, which are actually peanuts compared with the native files…

The advantages are as follows: Filesize, as you have mentioned. They can be worked on in parallel - disciplines can independently develop certain BIM data (such as an FM team working on asset data while the modeling team is working on geometric shapes) Not only can they be worked on in parallel, t…

@Moult many valid points, thanks. i’ve never considered a native platform like bim 360 as a viable solution for bim level 3, though. i can get the notion of the managemenet of those two entities separately, but it’d be a double management, right? is there no danger of disintegration of created in…

Thank you @klaus.aengenvoort , I’m familiar with PDT and PDS and I was guessed about PDV too. However, all of these are focused on “Data/Information” side The idea I have in mind is that we separate “Geometry” which I call “Model” because of some reasons from “Data/Information” And “Geometry” has …

thank you, ehsan, you’ve got the point: different levels of log (level of geometry - i like this name bias i’ve seen in one swiss presentation) and loi for the particular project stage :slight_smile: this is reason enough for me.

Thank Robert, for me simplicity and performance of the information system I dream is important. And all together will work hand in hand to bring it to reality

Two of the commonly known MVDs that are officially approved by buildingSMART are the references view (RV) and design transfer view (DTV) (bSI, 2015b, bSI, 2015a). The RV is defined as a subset of the IFC4 schema that comprises a set of MVDs for reference workflows such as iterative design review an…

[lod_explained] In computer graphics , accounting for Level of detail [1] [2] [3] ( LOD ) involves decreasing the complexity of a 3D model representation as it moves away from the viewer or according to other metrics such as object importance, viewpoint-relative speed or position. Level of detail t…
