Cut and fill topography

[nima_hakimjavadi]

I have existing contours of topography and filling contours  but there some problem, first filling contours started from the level of exciting as you know in reality should be start at the exciting surface because of that the volume of filling is incorrect. second problem i need couple of cross section to show the location and level of exciting site and construction site unfortunately I can not change the cut pattern of each one I mean when change one of the other one is change too and comparison is impossible. 

as well as about process of modeling:  all data base  came from auto cad and first extrude a exciting contours then filling contours. 

thank you for your time, many thanks for your help

Very difficult to understand the workflow and issues you are describing. Can you Screencast  what you are doing?  Maybe posting the RVT would help as well.

1- Link existing CAD topo in, create existing Topo in Revit from it
2- Grade region the topo to create a new/identical topo
3- Link the new CAD topo in and adjust points of the graded topo
4- Create cut/fill schedule and the volume should be correct

first at all thank you for your attention. you know, imagine there are a site property with individual topography until now no problem I use cad link upload it at revit and can make easy 3D topo, but we decided elevated the site artificially (fill earth) but looks like natural earth land, this part have individual topo contours too so i make 3d topo just for this part now. problem is here site have existing topo at the different level fill earth should be start at the existing level but start at the level 0.00 same as existing topography. by the other hands because of project dimensions adjust the earth fill manual is not possible(45 Hectares) just i can import fill earth contours which is prepared by landscape engineering. at the attach file green surface is existing site and gray one is fill earth. when you get sections will understand the problem. 

I hope I have been able to convey my point

Hello,

item 1 you said there are to different layer one existing contours second earth fill contours which one you mean?

please look at the attach file in below the cyan color are earth fill contours and the others are existing 

 also for item 3 you said adjust the new contours is not possible because of project dimensions there are individual contours just for earth fill (cyan color)

I really appreciate for your time.

Do you realize that a Toposurface is just a surface? A Toposurface has no depth. What you are seeing in cross-section is only symbolic.  It's the Poche. Adjust the "Elevation of poche base" under Site Settings. You'll see what I mean.

but here you said just you can say new topo start from which level but existing topography have lot of levels and bump 

[nima_hakimjavadi]

when earth fill start from incorrect level means volume will be wrong right? earth fill most be continue from existing topo surface not same level of existing topo

Huh?  I didn't anything like that.  

BTW: are you using a language translator?  If so, could you try using a different one? No offense, but whatever you're using is doing a terrible job.

please look at the section too

I understand my English language is weak sorry about that.

just I wanna say when earth fill start from wrong level volume will not correct. 

I don't use translator by the way thanks

Please look at message #6.

Try using one then.  I'll let you know if it helps.

in the site setting at message #6 when you change elevation base all start at one level but natural land every location have a different level
