Title: Pipenetwork, Assembly, Earthwork
Post by: cadplayer on April 15, 2015, 04:28:06 AM
Hello!
Iīve been working with Pipenetwork in Civil since a month. I have created a functional Pipenetwork with different types of Pipelines, with dimension, slopes. My problem is I want continue with calculating earthwork, but I didnīt understand right which way I have to go.
Solution1 - Subassemblycomposer
I want create a corridor of 3 pipes which are next to each other. The pipes have different slopes and deepness so I need more than one Assembly or is composer so intelligent to give them parameter to follow 1.pipe-1.alignment 2.pipe-2.alignment...

Solution2 - Create a surface from pipe ground
What are opinion with CREATEALIGNFROMNETWORK, can I get 3dPolylines from my Pipenetwork ? So I can create the ground manually with featurelines

Or have you a better way for me?

Thanks

Yes there is a way to get earthwork volumes...for your pipe trenching and select material backfill, etc.
NO, you do not have to use sub assembly composer to do this, it can be done with generic links, and assemblies from polylines.

I will prepare a small sketch to give you the basic idea and post a little later.

ok the sketch attached....is an outline of what one would do if there is a single pipe in the trench


what one does is create an assembly
use generic link to get the section down to bottom of trench
then either using assembly from polyline, or generic links create the outline of the select fill to first backfill level
there is a way to approximate thee pipe outline using link width and slope links to approximate the pipe section(s)
then the additional fill material section(s) are created in similar fashion.
the top of trench can be done using pavement sub assemblies

you will find that IF you do this with generic links before atttempting with Sub Assembly Composer it is easier to do ( from my experience)

Naming conventions and use of the USE value from other sub assembly components makes this easy (relatively) to do.
Poor naming of assembly component(s) and or target parameters....you will have a bad day and poor results.

Hi Michael!
Thanks for reply, I understand the composer is not really a need in my case.
My 3 pipes for water&sanitary goes in different deepness and slopes. So if I create an assembly I would say follow 3 different profiles otherwise I have to design a lot of assemblies to get it right.
I have done a subassembly from a Polyline in definition of sectiontype, so that is not the problem.

Some pictures say may more

Dirk your situation could still be done in the manner suggested.

Option 1

You could treat each pipe cl as an alignment and get volumes for the trench section
for each pipe
This could be done using either offsets within the assembly.

Option 2

Just use generic links.


I say use generic links, as they have the ability to be assigned different, and unique Point, and Link, Codes
These allow you to then create all the surfaces required to get all volumes for trenching and back fill material(s)

The reason I would NOT tend to use assembly from polyline, is the process to assign point link and shape codes annoys me.

Very good help Michael, I get solved now. Thank you and have a nice WE!
