Reading a Shoegnome post recently I came across a concept which I have integrated into our latest template version. That is a layer intersection group “0” for all layers not shown in the current layer combination. While I don’t normally recommend mass attribute purging for most projects, this suggestion for layer management has huge potential to improve the way your model views in 3d and elevation.
Layers that are not visible can have an impact on the model. For elements like the operators of an SEO this is a good thing. For things like roof only walls or trim elements that show up in one view but not all this can be problematic. You can end up with elements that are turned off which are interfering with the appearance of your model. By changing all layers which are off for a specific layer combination to intersection group “0” you reduce or eliminate the chance of this happening.
