Make an undulating ground by floor

[Anonymous]

Hello,

Could you give me some advice?

I want to make an undulating ground and see it in three-dimensional volume.

And see the grade after excavation and elevation, and before it.

I know, [Toposurface] has only surface ( I can't see a real three-dimentional volume),

and it can't work with [Cut Geometry].

So I usually use Floor as WorkAround,

but I don't know how to make floor undulated.

Ground has tons of level, so

Do you have any good idea for make floor undulated easily?

OR

Any idea for see Toposurface in three-dimentional volume?

I wonder this way...make 3Dvolume and cut its top by Toposurface as WorkAround,

but I don't know how to do that neither.

Please excuse my poor English,
If you have any trouble understanding my English, please feel free to ask so I can clarify as best as I can.

Any assistance would be greatly appreciated,

Shape edit the floor using Modify Sub-Elements tools. 

...if your topo is derived from a dwg, you could use the dwg as the basis for a mass element, and then apply Roof to faces of it.   

...You know you can "see" Topo volume by enclosing it with a 3D section box; don't you? You can change the depth of your poche through site setting.

Thank you for your advice, @barthbradley

I tried >Shape edit the floor using Modify Sub-Elements tools.
and it works!

And I am interested hear that, >use the dwg as the basis for a mass element, and then apply Roof to faces of it.
Could I hear more about that?
Does it shorten the time?

Now, I do this way,
Import CAD > Make floor with [Pick Lines] > [Add Point] > [Modify Sub Elements]

Start an In-Place Mass. While inside sketch mode, insert the DWG. Close out of In-Place Mass sketch mode (ignore warning). Click on Roof by Mass Face, select all the faces of the Mass, and then click Create Roof. Done.

Just make sure you are fitering your "Floor Topogrpahy" from any true Floor Schedules! (This is why I don't really like using Revit elements for objects well outside of their scope)

@Anonymous: Actually, I think you ought to stick with Floor on this one. You're going to need the "Variable" setting checked to create the "fill" - which essentially is what you are after, and why you're not liking the Toposurface. 

[ToanDN]

Why not using a mass to manipulate the surface elevation variation?  It is easier to push/ pull points, interact with voids, the surface is smooth, phases works properly.  He can later create a floor by face if he fancies it, or just assign a material to the mass and use it to present the ground.

[barthbradley]

Of the 2 suggestions I made, only one would actually give him the results he was looking for. Roof by face wouldn't "fill" core; variable Floor would. But, yes he could mass it as well.

I think it works with 3D DWG, does it right?

Now, I only have 2D DWG.
It doesn't have level(Z parameter), and doesn't have contour line neither.
It only has survey point---2D circle and text of level.

I want to give it try, make with Mass, but I don't know how to pinch each level point on Mass object.

Could you teach me how to pinch it?
OR
Do you have any idea for prepare on DWG(AutoCAD) and make with it?

>It is easier to push/ pull points, interact with voids, the surface is smooth, phases works properly.
Now, I'm interested in using a mass, but I don't know how to pinch each survey point.
I know how to push/pull perpendicularly from surface,
but I don't know how to pinch point with measurement number.
Could you teach me how to do it?

Thank you for your kindness, @bimscape
I know that point, so I use Filters with Filter Rules.

Thanks,

@Anonymous: You're asking for some difficult methodologies to describe in a post. "Pinching"? As in pulling together two edges? Wow! Sorry, I ain't that articulate. But, seriously; a shaped floor is the way to go for you here. Just make it a "Variable" thickness, so that when you "pinch" and "pull" the top of it - it leaves a solid core beneath. Get it? You will. 

[ToanDN]

The only beef I have with using variable thickness floors is getting lines everywhere instead of a smooth transition. But if OP can live with it then good.

@ToanDN,

I agree with your point of dissatisfaction,,,

Sorry for bothering you, Can I ask what is "OP"?

Why do you agree with @ToanDN's "point of dissatisfaction"? 

..."O.P."= You

[ToanDN]

OP is Original Poster, in this case, you sir.

@ToanDN,

Thanks,

If it is the fastest way, I close my eyes.

@barthbradley

First, I'm sorry about my poor translation.
"Pinching" might have different image between English and my language,,,I MUST study more.

>a shaped floor is the way to go for you here.
so, now, I'll make by Floor.

And Why I agree is that,

I wonder there is more possibility like this,,,

but it won't be necessary for now.

No need to apologize, @Anonymous. You're family. All's good.

I appreciate all your kindness!

I'm trying make with floor, and now, I have question,

How can I fill this hollow?

Either is fine, work with only one floor, or work with two or more objects.

Could you give me some advice?
