underground floor and car lanes

[Ciuchin0]

I found several discussions about it, especially for the creation of car lanes.
I still have a few questions.
I do not work on topographic surfaces, but rather close to a plate (created with the command foundations: plate) stratigraphically I care to place a screed in cls that base for the pavement of the basement, ergo I believe to have to create a "floor" thickness 10 cm above the plate. for the creation of road lanes, signals on the ground etc as a continuation? Do I always make floors? and what thickness imposed? 0.001 m? Why do they see? thanks for the advice.

always depends on the families you use:
- 2d families are already wired floor
- 3d families (horizontal) are placed a "wire" above the floor level

do you know the use of layers in floors and walls?
I ask why it is not neccesary to draw so many "floors" as many layers, it is enough only one, or at most two if you use the counts of the abachi

 

[Ciuchin0]

I know the layers in the floors, but for what I have to do, I think it is necessary to do as I said.
Anyway, I finally solved this way:
for the lines on the ground I created a mega family that I "laid" over the host plate and dead there. the floor (i.e. the screed) I created it but then also erased because I do not understand why the walls did not understand that there was that floor (it was not structural) and therefore in the 3d view the edge of intersection was not seen.
Is there a way to solve that problem by chance?
thanks again gfrank for the availability and attention you give me

send the section, to better understand ....

mah, I solved by layering the plate element, rather I would like to know how to put the "strikes" also on the ramps. and above all, why (always the ramps) do not come to me of the same color of the floor (on property have set the same material, that is the reinforced concrete)? But white? and other color problem. Why do I use the family posted by you and modified by removing the pedestrian door) not see them in their color? They look like "diving" in the wall. I didn't dissect the wall, I just inserted the "basculating" family shouldn't she cut the wall? to the wall selection you see the door cut, but then you see this... boh?
I wanted to change the color of the walls, but in the property window like I found nothing.. .

 

[Ciuchin0]

ok, for the color of the wall I understand, you have to edit it and vary it in the dialog of the layers!

 

[Ciuchin0]

I've solved it with a shovel. ..change the materials always from the window "change type". I thought I'd do the same thing with the structural pillars, but I can't find the option there.
in the case of the pillar how do you edit the material?

 

[gfrank]

the pillar, it seems, does not have the material parameter, so you have to open the family (in family change) and add to the pillar a parameter of material

 

[Ciuchin0]

yes exact gfrank, I edited it from them and now it is ok. thanks as always.
