Click on the AutoLevelMark ribbon button under the Add-ins tab or open the Tool Palettes under the View tab in Autodesk® AutoCAD®.

Right-click and select the AutoLevelMark palette. Now click on the Block to insert the Mark.

After importing the block into your section or profile view, set the desired reference level (mass) from the block properties panel, for annotative blocks also set the display scale.

Now copy the block overlapping it by the number of layers you want to show, then using the move grip on the visible layer arrange your layers as you like.

Now with a simple "regent" your levels will update considering the distance from your reference and its value.
