Hey guys need some help, cant work out what im doing wrong here, using Revit 2012

Wanting to create a road+Curb surface, have spilt my surface for the road and one for the curb.

Was attempting to merge the surfaces to create a straight sharpe edge between both ( result a curb next to the road), and what im getting after merging the surfaces is a steady incline. have unticked 'remove common edges' 

what am i missing ?

this is what im trying to achieve

This process works but you have to do all the steps.  You did not do this one:

Now, using the Split Surface tool again, Split each of the four 6" spaces 1/8" from the their shared edge - creating (2) 1/8" slivers of curb in between each of the two 6" pieces.

Those are the two surfaces that are merched to create the curb face.  Thus the face slopes the curb heigth in 1/8"

thanks for the respone guys,

Feel like revit makes it hard creating sloped site materails such as roads and footpaths. Could be made so much easier,

Working with toposurfaces are a pain and with lots of changes throughtout the desing process, you would be wasting alot of time on them  

Finding using floors and editing the levels that way may work out the best, 

thoughts ?

Forget using levels.  You can use floors on flat sites but trying to do it irregular topography is tedious and usually not successful.

Typically civil details all of the sitework and we only need to show the surfaces so I only do that.  Your split surface process is what I use when I really need to see the curbed surface on irregular sites.   For close up views of buildings and parking areas where the site is simple slopes, I use slabs with walls for curbs.  (you can also use a slab edge).
