There are quite a few "Smart" entities in TBC that default to layer zero. I want to put in a feature request for a spot in project settings to select the layer that these entities would go to and avoid dumping these on layer zero:
Entities that default to the zero layer:
- Plan Sets
- All new layers in plan sets default to zero
- Cross Sections
Entities that do not default to zero but would be nice to set default layer:
If I think of anymore I will add them to the list.
