Get Curves of levels

Hello guys just got stuck on this one problem can’t figure out by myself and couldn’t find anything on the forum also.
Here is the query.
I have internal elevation views of rooms which are 4 in one sheet and total of 100 rooms. That means i have to place detail component 4x100x2 where 2 no. is the detail component i have to place in each view. detail component which looks like level but it isn’t i have already created the family i m not able to vertically align it to the levels in the view i need to get the either curve of the levels in the view or place a model line over level so that i can place my detail component by curve with slight modification in z value.

Any help is appreciated.
