Constraints
Elevation Base	Controls where the elevation of the level is measured from. If the elevation base value is set to Project Base Point, the elevation is measured from the Project Base Point. If the base value is set to Survey Point, then the elevation is measured from the Survey Point.
Graphics
Line Weight	Sets the line weight for the level type. You can change the definition of the line weight number using the Line Weights tool. See About Line Weights.
Color	Sets the color of the level line. You can choose from a list of colors defined in Revit LT, or define your own color.
Line Pattern	Sets the line pattern of level lines. The line pattern can be solid or a combination of dashes and dots. You can choose from a list of values defined in Revit LT, or define your own line pattern.
Symbol	Determines whether the head of a level line displays a level number in a bubble (Level Head–Circle), a level number but no bubble (Level Head–No Bubble), or no level number (<none>).
Symbol at End 1 Default	Places a bubble by default at the left end of the level line. When you select a level line, a check box appears next to the level bubble. Clear the check box to hide the bubble. Select it again to display the bubble.
Symbol at End 2 Default	Places a bubble by default at the right end of the level line.
