realization model of study

[Danig]

for the first time I would like to try to realize a model of study with revit, without resorting to the "usual" sketchup.

for the "base" I have the cartography with the quotas, it is gross in plan but anyway with that I can reconstruct a fairly reliable model.
for buildings just use the imported dwg and create masses, right?

but how do I behave for the sidewalk (we are at my) and road pavement?
floor or anything?

if you need to highlight "only" roads and sidewalks use "subregions" or "divid surface"

if you need to "plan" the soil uses "plattaforms" and then solid with extrusions

 

[Danig]

even if I'm late, here I am.

Okay, I'm trying, but is it right that I have to create a local model for every mass?
because otherwise I have to load the families who have their forms.
does not weigh the file when I have 15/20 masses?

Here I go in crisis, in the course followed in university we took a very quick look at planimetry.

leaving the level curves (almost flat), how should I proceed?
I'll have to have a level 0 base with asphalt, which I can solve with the first topographic surface, right?

then to +10cm about the various sidewalks, but they also include all the isolated inside, so I do not know if I should use the platform or make a new surface to +0,1..

above this surface I will extrude the various volumes of the buildings (masses) and insert my molded.

How do I proceed?

already that I have a last question always on the topic planimetry: How do you behave with the soil when there are underground elements?
For example, I will have to insert some local 1/2 basements, how do I make the surface cut perfectly in correspondence of the floor and the walls underground?

1. masses.
creates many masses with the use of the family of "conceptual masses" which then amounts to the project
2. the topographic surfaces cannot overlap.
3. define the level = 0
4. use the platforms (even with a very few mm thickness) to create the "base of support of buildings, sidewalks and roads at various altitudes. uses as many platforms as you need, remembering that they too cannot overlap. the same "scavano" the soil to the necessary depth set.
e.g.: if you have a 10x10 m building that starts at altitude - 2 m, make a 10x10 platform at altitude - 2m.
around this at altitude 0 make a second platform for the sidewalk, to which overlap the sidewalk (floor or mass) thick 10 cm. etc.
5. above the platforms insert the various masses created with the family of conceptual masses, possibly divided by type, so that for each type you get the values of surfaces and volumes.
es: in the building 10x10, insert
at the altitude of - 2 m
- a mass of 5 x 10 x 2.5h = cellars
- a mass of 5 x 10 x 2.5 = car box next to the first
at + 0.5 m
- a mass of 10x10 x 9.3 h = building of 3 floors with apartments, shaped so that it has a "hole" of 5 x 2.5 m (scale and elevator) on all height
- a mass of 5x2.5 x 11h = column stairs/lift (possibly also divided into two masses to differentiate the stairs and the elevator column)
....
the roads and sidewalks in turn are superimposed to the respective platforms, executed with masses or with extruded solids
....

the problem is that the buildings (with the masses I reconstruct the sketched volume of the other buildings) do not have perfect geometric shapes, so I should do for each building a family purpose, importing every time the dwg to recalcate the base. .
becomes long, is it the best procedure or can I use the local masses?

2. the topographic surfaces cannot overlap.

ok

3. define the level = 0
4. use the platforms (even with a very few mm thickness) to create the "base of support of buildings, sidewalks and roads at various altitudes. uses as many platforms as you need, remembering that they too cannot overlap. the same "scavano" the soil to the necessary depth set.
e.g.: if you have a 10x10 m building that starts at altitude - 2 m, make a 10x10 platform at altitude - 2m.
around this at altitude 0 make a second platform for the sidewalk, to which overlap the sidewalk (floor or mass) thick 10 cm. etc.

ah, perfect, actually so is right. . !
but the platform consequently use it as basement floor, right?

5. above the platforms insert the various masses created with the family of conceptual masses, possibly divided by type, so that for each type you get the values of surfaces and volumes.
es: in the building 10x10, insert
at the altitude of - 2 m
- a mass of 5 x 10 x 2.5h = cellars
- a mass of 5 x 10 x 2.5 = car box next to the first
at + 0.5 m
- a mass of 10x10 x 9.3 h = building of 3 floors with apartments, shaped so that it has a "hole" of 5 x 2.5 m (scale and elevator) on all height
- a mass of 5x2.5 x 11h = column stairs/lift (possibly also divided into two masses to differentiate the stairs and the elevator column)

ok, but this at the moment is too much, I just need to extrude the volumes of the buildings around with only one simple mass, which has the base lined by the dwg.

the roads and sidewalks in turn are superimposed to the respective platforms, executed with masses or with extruded solids
....

I thought of making a surface for asphalt, level 0; to +0.10 all the various sidewalks and support points for the masses (and for my building).

I would have a different approach... Also because then you can't handle everything, unless you have a megapower ws. .

I divide the project into two separate parts
1) the final environment (where I see everything, I make renders etc.)
2) the houses

in 1 I create the topography on the street floor, with the level quotas etc., I make "holes" endlessly in the territory corresponding to the pdf of the houses. in the ambinete I put the sidewalks with the bends of the road etc. If you want to exaggerate, put the sewers and all the planting.

the houses I build them in rvt (projects) absent, with basement and what else, including lights etc... possible interior decor is a further rvt.

then loaded as "collected" in the environment the various rvts in the precise holes.
go to a section in 1 and move the quota as you want of 2...

so you can work much faster and error-proof.. .
I recommend making a specific model before starting, ugale for 1 and 2.
especially if you want to have the 4th dimension (5 6 7 8), no less the visibility of the plans (for the final tables) is consistent.., also the materials render.
in this way if you mistake a structure you change it individually and quickly.

I have not understood much, sincerely:biggrin:

Maybe I didn't explain the situation well, it's easier than, maybe, I made it clear.. I have to realize the only volumes (I take the base in plant and extrude it in height, point) of the buildings around, then I go to realize my building within this.

but then do you use it to continue?
in the bim never "go back"... If you do a revit study model, it's likely that you can continue for an advanced project.
Why use a bim?
so much it is worth setting it in this way in the processes of work. . .
belong the fact that if you have to make a presentation you have the possibility of a huge graphic management...(full colors etc.).
you can have different construction times for both the environment and for individual buildings, you can insert evolutions or demolitions etc.

I started with projects of single masses to insert them as connected in a general project. so you can manage huge numbers of masses (a whole neighborhood..) and a huge number of "allegates" that are not families, like rivers, walls, etc.

Obviously I would go ahead, not only remains a model of study.. at the end I will have my building inserted in the context (abbott).

Before learning how to use revit I used sketchups, but since I can use it sufficiently, why not create context and insert the project directly into revit?

the "problem" is that the masses are simple parallelepipeds, make them separate or create a family purposely maybe it takes me a lot of time, so I asked: if I make a local mass for everyone, I weigh a lot of the file?

....use sketchup is done on purpose... then you expose it after you need it in revit...

If you use only the masses you can do as gfranck says.. I wouldn't. .

I had also thought of that, but at the end of the project I will still have to integrate the around with the new building, and I would not like that importing in revit (but is it possible?) there are problems. I wanted to leave and do everything with revit.
