Wall to Wall Relationships

Walls can relate to each other, and other element types, based on several factors. First, layer intersection priority defines which layers will intersect. Second, building materials determine how different composite or custom profile skins interact with each other. Lastly, wall/beam junction order determines in which order walls or beams will intersect.

Layer Intersection Priority

Walls with different layer intersection priorities do not intersect in plan. Walls overlap to their reference line.

Building Material Priority

Design Options With Hotlinks

If you have two building designs for the same site, you can avoid multiple site models/building models scattered around your model environment by creating two new layer combinations.

First create two new layer combinations module option A & B, then three new layers. The first is the “modules layer” which contains all common hotlink elements.The next two layers are the toggle layers, one is only on with layer combination “A”, the other only layer combination “B”.

The last step is to assign hotlinks to one of the toggle layers (I learned something new about this today!). First select the hotlink to be assigned to toggle layer A, go to File > External Content > Hotlink Module Settings.

Change the Master Layer for this module to the correct toggle layer and follow these steps for each module which will be part of the option A or option B schemes.

Layer Intersection Groups

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,┬áthis 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.
