Hi, just doing a very basic single storey house in Revit Architecture 2009.   my first proper attempt at doing a project on revit.

Im totally lost with the site topography. ive set one up with the levels as the site slopes slightly.  i have my building model basically complete, with a slab as a floor, but the only way to get rid of the topography coming through my building is with a pad?? and i have to apply a thickness and structure to the pad even though i dont actually want it, i just want to cut out area from the site topography?

struggling to explain. basically im in a mess with whether i should be using pads for slabs and external paving etc.  cannot find a simple walkthrough on how to set this up correctly. im guessing its simple im just missing something.

appreciate any advice. thank you.

Hi Typhoon,

I would appreciate another video if you are able to post one. I am relatively new to Revit and am doing my first 'real' project which is a set of three townhouses on a sloping site. I am finding the Topo/Building Pad issue to be where I am most getting stuck and would love some help.

I have managed to get the site topography done based on an imported CAD file, however each townhouse is set down 300mm from the next in order to follow the contours. I am wondering how to cut/split the site to match the change in levels - would the best way be to split topography or create building pads?With either option, would I need to do just one version or three i.e one building pad for all 3 townhouses or 3 separate building pads?

Thanks for any help in advance!

i'm lost...just don't know what sequence to take.

i've imported CAD survey plan into my site plan. Went to Site/toposurface...set properties to earth material.

meanwhile, i've created sea level and to simplify my exercise, i use the building slab as 0 level, above 8500 sea level. don't understand

project shared coordinates.

i used the property tool to  copy the cad property lines. do i use this outline for the pad?

i tried the parking components, how do i place it? do i place it after i create a pad?

stress!

Lilian, there are several things I don't understand: 1º "i've imported CAD survey plan into my site plan. Went to Site/toposurface...set properties to earth material." - Did you already create you surface/site in Revit????

2º "i've created sea level and to simplify my exercise, i use the building slab as 0 level, above 8500 sea level." - You are working in what units??? MM, Cm, Meters, Inches, what???? so you put your slab in the "level 0" and your "sea level" is 8500 UNITS above the Level 0, OK.

3º "don't understand project shared coordinates." - Did you check in the HELP menu or in Tutorials How it Work???

4º "i used the property tool to  copy the cad property lines. do i use this outline for the pad?" - ????????

5º "i tried the parking components, how do i place it? do i place it after i create a pad?" - YES OR you can put those components directly in the Surface, Grading.....

6º "stress!" - Don't stress, explain this questions and put some screenshots about what are you trying to do so I can figure it out and I belive someone can help you....

yes

mm

3º "don't understand project shared coordinates." - Did you check in the HELP menu or in Tutorials How it Work???

i read 2 books - introducing and implementing revit arch 2009 and the other introducing revit 2009 but i will try the again.

4º "i used the property tool to  copy the cad property lines. do i use this outline for the pad?" - ????????

don't know what the property tool does?

5º "i tried the parking components, how do i place it? do i place it after i create a pad?" - YES OR you can put those components directly in the Surface, Grading.....

maybe i cancel the topo surface and this is why the component cannot place . i will try again.

6º "stress!" - Don't stress, explain this questions and put some screenshots about what are you trying to do so I can figure it out and I belive someone can help you....

 thanks for encouraging...i will try again :-)

Tyhoon,

here are some pictures of what i have done after going throught the tutorial

createdtoposurface

created subregions for roads, walkways and grass areas

i've set my site plan at 0 level.the site highest contour line is 9500( mm ).

i think i will have to do the pad for the building, parking and walkways so they are cut into the earth..... is this right?

Hi,

"createdtoposurface" - Good

"created subregions for roads, walkways and grass areas" - Correct

"i've set my site plan at 0 level.the site highest contour line is 9500( mm )." - OK

"i think i will have to do the pad for the building, parking and walkways so they are cut into the earth..... is this right?" - BINGO.... If you don't use the Pad's in your buildings (i.e.) your surfate (topo) gonna appear into the rooms, kitchen and so one, don't put thickness in the pad if you use normal slabs between the floors, for the parking and walkways remember, the PAD it's similar to a FLOOR (SLAB) so you can assign inclinations tor your PAD's if you need... OR sometimes i just use Pad around my building and the rest i change the elevation points like i want and use Subregions and if i need I "Split" the surfaces in several parts to create my final toposurface.... You must see what do you need and how do you do it... You have the tools in Revit so USE IT...

i messed up the toposurface...:-( now that the road gets into the earth. i used the grade region /toposurface/points/window delete the

contour points in the parking, walkway and grassland and this is what i finally got...looks like a mess. i don't know what to do next..i'm 

just so tired now ..3 hours in trying to get the site level right .
