I'm having a lot of trouble achieving a successful graded toposurface at retaining walls, particularly where revit has generated a lot of points from an existing contour survey. I find that i have to create a very large number of new points to get anything that even remotely resembles an accurate surface. Are there any shortcuts or alternative techniques?

Here is a JPG of what I am trying to get done. How do you remove the topo down to the floor level so that the door and deck are not buried.
Thanks

if the topo is at the right height hopefully it is if you took it from an imported civil drawing. it's a matter of what the house should be at for it's z height. Look at it in elevation and select everything you want to move up. Type in the new height on the datum. It's at 0. If your topo is poking through the building which in most cases it does unless you have a super flat surface, use the pad command under site and set it's height under the basement height so that way it blocks out the surface from coming in.

to make a better surface it is better that you have closed splines or plines. i draw it in autocad then give it it's z height. go through and do a laywalk making sur everything is closed and joined. that way seemes to make it the best and not have to bs it's topo like it does.

Still trying to figure out how to do this. I tried the Building Pad but it doesn't alow any slope and shows a line in the drawing were the pad ends. Grading does work because it wants to slope everthing. I need a clean cut. I made the walls retaining but it appears to have no effect. Why are they retaining IF THEY DON'T RETAIN anything!
Any more ideas? Thanks in advance for any help.

i know this was posted two years agom but was anyone able to answer NewBe's question? do retaining walls "retain" the topo or do we have to manually manipulate the topography ourselves?

nevermind. "Split Surface" is the way to go to make voids and whatnot in your toposurface. yay.

its ok as long as you don't have to create a cut/fill schedule, if you split and delete it will not be included in the schedule
