Toiture jardin

[Anonymous]

Hellooo

Hello I hope you are well I have a quick question , how I can model a garden on a roof I tried the topography but the solid ground appears in the cut suddenly I opted for a variable slab. I don't know if it's the right solution. Thanks, have a good day

Bonjour j'espére que tu vas bien J'ai une petite question
, comment je peux modeliser un jardin sur une toiture J'ai essaié la topographie mais la terre pleine apparait dans la coupe du coup j'ai opté pour une dalle variable . Je sais pas si c la bonne solution . Merci Bonne journée

Hi,

Yes this is a limitation, Revit should adress this. For instance a underground parking structure top soil can't be created with Topography.

The top is determined by the Surface foundary points and the bottom is set by the Elevation of poche base.

A variable Floorslab can be used, I prefer to use a Model in place, Topography family, so the category matches.

Thank youuu 😄 i will try it

You could still do that with a topography. To avoid the earth pattern from getting into the rooms, go to Site Settings and set the "elevation of poche base" property to a small value, such as -1".

thank youu but i have already a topography in the 1st floor so if i will change settings my site will change too :///

in such a case, like yours , when having small piece of terrain, I'd rather use a Conceptual In Place Mass to create the infrastructure and then a Roof by Face over it in order to be able to use its Layers.

• The Mass element is created using Closed Profiles and Loft. These Profiles can be either Vertical Profiles (as in my example) or they could be Horizontal (Closed) Profiles , in this case they will work similar with Isocurves from Revit Toposurface 
• once the Mass created I apply Roof by Face because this allows using of Layers of materials
• if you don't need material Layers, then Mass could be enough.

If there is already another topography with other settings, if you still want to do it with a topography, you could do it in a separate file, change the settings for the poche, and link that file into the building file.
