tunnel and topographic surface

[nicnoc]

well I have my topographic surface and I have to create inside a tunnel with a vaulted cover.how do I do?

 

[gfrank]

insert a platform, which base of tunnel support, do your tunnel with an extrusion on path (e.g. structural family),indis:
- if the extremity of the time is on the floor, insert a "floor" up to the level of the ground, with "earth" material;
- if the extremity is also an arch, insert again a "fill" (always with extrusion on path) to which material checks "terrene"

or
- make the topographic supeficie with depth of a few cm of "poche"
- under the topographic surface do a "solid" (extrusion) of the thickness you need
- use the blanks to "dig"
- uses solids (extrusions) for vaulted structures

of course the solids of the structures will be assigned the various materials (cls, etc.)

 

[nicnoc]

I didn't understand much.
I did not know you could give a thickness to the surface

 

[nicnoc]

Now I try and see that I can do

 

[nicnoc]

insert a platform, which base of tunnel support, do your tunnel with an extrusion on path (e.g. structural family),indis:
- if the extremity of the time is on the floor, insert a "floor" up to the level of the ground, with "earth" material;
- if the extremity is also an arch, insert again a "fill" (always with extrusion on path) to which material checks "terrene"

or
- make the topographic supeficie with depth of a few cm of "poche"
- under the topographic surface do a "solid" (extrusion) of the thickness you need
- use the blanks to "dig"
- uses solids (extrusions) for vaulted structures

of course the solids of the structures will be assigned the various materials (cls, etc.)

what does it mean surface of a few cm?

 

[gfrank]

in the settings of the planimetry, which manages the thickness of the ground, in the views in the area and section

 

[gfrank]

... so...

 

[nicnoc]

I'm proving now.
My surface is a little more complicated, but I will.
Mr g.frank in the meantime took the opportunity to ask if you think it is worth buying the books of the augi "new edification" and "structures", to deepen revit

 

[nicnoc]

then if I give a value to the few as you say, in section I remain the ground; If I design the tunnel through extrusion, inside it remains the net of the ground.
if instead I give a value to the few of 1000, the problem disappears in section, but in the plant, at the section level of the tunnel the problem remains in both cases

 

[gfrank]

I don't know.

 

[nicnoc]

Here's what happens to mehttp://img529.imageshack.us/i/76332563.jpg/This is actually a second test, you never had wrong the topographic surface. But it is identical to me before, I don't know how to do and I don't know where I'm wrong

 

[nicnoc]

excuse but the tunnel create it by modeling in place using which type of family?

 

[gfrank]

the thickness of the "poche" = -4.000 what are: cm? m? (reduce it to -1 cm)
p.s. measurement unit = to the one set in the project!

under the few you have to make a solid by extrusion, family (foundations, but is equal to other quality), in the form of parallelepiped, extended as the surface and as deep as you need..., to which you check the material "earth"

in the solid below the surface, remove the tunnel area with an "subtraction vacuum", (extrusion on path) increased by the thickness of the supporting structure.

so far is my design that I have posted

continue inserting the structure, as from your post, always with extrusion on path:
- path = tunnel length (or vacuum)
- profile = empty profile (external part matching with vacuum profile), inner part = thickness cls (choice)

 

[nicnoc]

ok after dinner I try and see what happens to me, thank you thousand. I will also post the result

 

[nicnoc]

I don't know what I'm wrong but I can't, maybe because my land is at 490 meters and not at zero altitude?

 

[gfrank]

.... therefore, in the thickness of the few put the value:
a) 489.99 if the measuring unit is in m
or
b) 48999 if the unit of measurement is in cm

and the thickness of the soil, in section, will be reduced to 1 cm

 

[nicnoc]

OK, I have tried and in fact it changes a lot, my bad luck is that the topographic surface is very irregular, it varies between 490 to 523 but not in a linear way, so if I give an h of the few legibility I run a bit the retini.
Anyway thank you so much for everything, I learned something new that I hope will be useful
