Assembly with varying shape depth.

[clbears3510]

I would like the depth of the subgrade to have a varying depth and thickness based up a second profile or the existing surface profile, while the road surface remains consistent with the roadway design profile. In the screen shots the zigzag shape represents topsoil the client wants to remove and replace with compacted fill. I would like the top of this shape to follow a profile that I will draw at the surface of the existing ground, or the existing ground itself. The top of road should continue to follow the design profile.

What I have works fine if I hug the existing ground consistently at a specific amount but some area require greater fill.

Thanks

Hi @clbears3510 

Please let me know if i understood correct.

Looks like the samples of the existing soil failed, based on the specifications of the project. Then, according to specifications, when this happens, you have to excavate more and fill this extra excavation with suitable (maybe with imported, or existing treated soil).

Is it your case?

I can't find the snapshot zig zag you mention... 

[clbears3510]

The zigzag is the hatch in the image.
The client wants to remove the top 6 inches of the existing soil, (more or less), I need an assembly that will follow a design road profile for paving, base, shoulders, etc. But, I need the sub-base bottom to follow 6 inches below the existing terrain regardless of what the design profile does.
I understand I may need to create an additional profile for the subbase to follow.
In my sections, this would show a varying depth of subbase at the bottom, the top of the subbase would remain steady at the bottom of the compacted subgrade.
Hope this makes sense.

It can be resolved using Subassembly Composer (SAC).

Use the element named: "Surface link" 

If you are unfamiliar with the SAC, please do not hesitate to contact me for more information.

I do have access to SAC tho I have never used it, was hoping I wouldn’t have too. If that is how it is done though, my next question is, can I import an existing C3D subassembly into it and modify it to meet my needs? Or do I have to start from scratch?

Yeah, SAC is really easy to use, and helpful, so you may learn more about it. 

For your next question, yes, you can import some C3D subassembly into it then modify (Some subassembly is not).

Sorry for my wrong Email address, the Email: "vantamuct@outlook.com.vn" is correct (the previous missing ".vn")

Please resend me an Email, then I can send you a sample (I don't know why i cannot attach my file here).

Or more quickly answer: Skype: Vantamuct@outlook.com.vn (I do not check my Email frequently)

HI @clbears3510

I prepared the attached subassembly, rename it to *.pkt file to be able to import it in your model.

Its a fully parameterized subassembly including geometric parameters and string parameters for the codes of the points/links/shapes.

Before you use it please note the below

• all default values in the fields are meters. I think will not affect you, if you work with imperial system. I think the PKT will use the default system, only problem the subassembly may look little bit "weird" in the preview but you can fix by changing the default values i guess...
• When you are in the properties of the subassembly, in the tab "parameters" click the help file , i prepared a simple sketch to help you.
• I tested in the "Layout Mode" and "Road way" mode in the SAC environment and worked good. I did not have time to use it in C3D model environment. I am sure you will find bugs, but i guess will be minor and fixable
• This subassembly works for CD3 2024 and newer.

Test it and let me know for the results, to find out if it worth to rectify any points and use it.

Use the stock "StrippingPavement" or "StrippingTopSoil" Subassembly. I think in your case the StrippingPavement is the one to use.

If you do this type of work often, may I suggest this

CTC Software

Many thanks!! I certainly will give it a try and let you know how it goes!

Hi @clbears3510 

Kindly accept my apologizes.

In my previous reply i attached wrong file of subassembly.

Attached now is the correct file.

I am sorry again.

Try it and let me know
