How to generate multiple alignments from multiple polylines.

[Anonymous]

Hi All,

I have a question that is related to automation of a simple task. My background is hydraulic modelling of water networks. A water network for a city can be an elaborate system. Civil3d has well devised import mechanism to import model data in shapefile format.

For interference analysis, profile plotting and other allied tasks, the network pipes must have associated surface and alignments. Civil3d has multiple alignment generation options. However, it seems, all require significant man-hours (when it is a city scale branched network). I can dissolve the pipe network into polylines that can be used as objects for alignment generation. For each object, I left a unique integer ID in DF field (of the shapefile).Mapimport Shape with unique ID for each polyline

Create alignment from objects

Alignment generation definition to be replicated for each polyline object.

My question is, is there any application or script that can take the polylines and generate alignment for each polyline without requiring any user intervention? Attaching a sample file that contains the polyline objects that need to be converted into alignments. For the seven polyline objects in the file, I want to generate seven corresponding alignments; preferably named 'Alignment - DF'. The process should be automated.

Much appreciate a quick response. Thanks in advance.

how to use this codes ?

Hi Tim,

Thank you so much for writing this script — I was really excited to try it out!

I'm currently working on thousands of trackers for a large-scale utility PV solar plant, and manually creating alignments would take an enormous amount of time.

However, when I load the Lisp file, a window pops up with this:

„Object data table record ID was not provided.

Invalid record number.

Object data table record ID was not provided.

Invalid record number.”

I'm not sure how to proceed from there.

Could you please help me troubleshoot this? It would be a huge relief if your script could assist with automating this part of my work.

Thanks in advance for your support!

Did you make the changes to styles and layers as discussed in Post 31?

Dear Neilyj666,

I tried to modify the original script with the corrections on Post 31 but I'm still getting the error.

I attached as well the .lsp that I loaded. Please assist. 

Thank you!

Can you share the drawing - I have just tried it with my version from 2022 and it works as expected in 2026

Hi Neilyj666,

Attach is the drawing.

Each point in the line represents the tracker piles.

Thank you in advance.

I added the label sets, style and layer to your drawing that are shown in the lsp I sent in message 46—and all works as expected.

I then tried changing the sets, style and layer to ones already in your drawing but I got the same errors as you had...but I have no idea why this would be.

I have attached the drawing with new styles/labels/layer which works

Hi Neilyj666,

Was busy delivering the work and it was so time consuming. I was hoping to use the "Create Offset Alignment" to expedite the work but it turned out,  I can't also use it because the trackers are not horizontally aligned.

Thank you for spending time to address my concern. I will study the attached file and see if it works from my side.
