How to place a Fence using the 'From Flood' tool setting such that it will ignore boundaries within the area to be flooded that are on certain levels and without the need to turn their display off.
In some instances when placing a Fence by automatically flooding an area its useful to see all the information on multiple levels and in reference files, but when doing this the From Flood option will find these elements and in turn place the fence along these boundaries. The following will describe a method of how to exclude these references and levels when placing a Fence using the From Flood tool setting.
To ignore elements in reference file elements, turn the reference 'Locate' option off for those references that are not required.
Use the Element Selection tool to select only those elements required to be considered when placing the Fence with the From Flood tool setting. (None selected items will be ignored)

In this short video you will see a green boundary, which is the boundary of the fence required. ( Note that the lines are all individual segments so the Fence from Element option will not work in this instance ).
The red line is in a reference file attached to the design and is to be ignored,
The brown and white lines are on separate levels within the master model which are also to be ignored.
