BIM | Goodbye Design Layers - Hello Super Layer in General Discussion Posted November 20, 2016 · Edited November 20, 2016 by P Retondo I don't have time to read through this thread thoroughly, but to toss in my 2 cents' worth: 1 - "BIM" is a bit of a misnomer. What most people mean by "BIM" is 3-D modeling. Embedded information, which is the real meaning of BIM, is not seen on screen and the term seems to have nothing to do with the topic at hand, except to give it a certain cache. 2) Layers are for selective visibility, and getting rid of them would do away with a major capability of VW. Having both layers and classes gives us more control. I can't imagine anyone who really knows VW would seriously consider getting rid of layers. 3) I'd say that if you can't handle layers, just use one - except that you would lose the "story" capability. I find stories problematic anyway because when you paste an object from one to another, it doesn't account for the Z level baseline of the layer being pasted to, and appears at the wrong height. So I don't use stories, but from a logical point of view, as others have pointed out, it would be more sensible to tag objects as belonging to a story whereby they would augment their Z value by that story's height relative to the 0 datum. I can understand why VW engineers originally set up the story capability as linked to a layer, because that's how 2d was being done - different levels of a building were sorted by layer into separate floor plans, and this was being done before there were sheet layers. I do agree with the basic premise that it could be possible to model the whole building on one layer if we had appropriate ways to output horizontal sections mapped to floor level sheets, and if there were a more logical way to handle the "story" parameter. At the same time, I for one would find it very inconvenient to be unable to isolate sets of objects by layer. It would get to be an unholy mess to see anything.
