Visible: There are two states for this field, visible and hidden. The states are pretty much self-explanatory, entities in visible levels are shown on the screen and ones in hidden levels are not.
Selection: There are two states for this field, enabled or disabled. This controls whether items in the level are selectable. If a level is disabled it still may be selectable as lines but not as an object. Note that selection cannot be set to “Enabled” if the level visibility is set to “Hidden”.
Level: This assigns a level number to a level each level has a unique number in the range of 1 to 25.
Name: This is a descriptive name that can be assigned to each level. Note that when switching between levels via the drop-down menu, this is the name you will see.
Height: This is the most important field when setting up a level. Often, this field is confused with wall height. Level “Height” is used to define the level envelope. All entities fitting inside that envelope will be placed in that level. The level “Height” should reflect the highest point of the level. For instance, if most of the walls on the first floor are 8’-1 1/8”, but there are some walls (or beams) that are taller (say 9’-1 1/8”), the level Height should be set to encompass the highest object (9’-1 1/8”) in that level.
Displacement: This is the offset displacement adds separation between levels when viewing them in 3-D.
Wall top: This specifies the default wall top elevation for the level. When switching to a level, the default wall top box at the bottom of the screen in wall section will be updated to this dimension. The software will automatically assume that this field is the same as the “Height” field unless told otherwise.
Wall bottom: This specifies the wall bottom height for the level. This is both the default bottom height of the walls and the lowest most point of the level. When switching to a level, the default wall bottom box at the bottom of the screen in wall section will be updated to this dimension.
Wall width: This specifies the default wall width for the level. When switching to a level, the wall width box at the bottom of the screen in wall section will be updated to this dimension.
