Crear líneas paralelas (ductos) a partir de un atributo de cantidad en ArcGIS Pro

DoreliaZangrando

Hola a todos,

Necesito ayuda para crear líneas paralelas basadas en un atributo.

Me explico mejor: supongamos que tienes una forma de líneas, como calles y las llamamos TRENCHES.

Supongamos que cada línea tiene un atributo que indica cuántos ductos (o cables de fibra) hay en el suelo. Necesito una forma de obtener una forma donde se puedan ver todos los ductos.

Intenté manualmente usar Copiar paralelo, es decir, si la cantidad de ductos era 3, seleccionaba por atributo todos los segmentos de línea con cantidad 3 y luego copiaba paralelo 2. Así que 1 era la línea original + 2 copiados = 3.

Lo que necesito obtener es un nuevo shapefile donde se puedan ver todos los ductos (o cables).

En la imagen 1 y la imagen 2 puedes ver a qué me refiero pero hecho en un software de planificación FTTH. Solo me preguntaba si ArcGIS Pro podría hacer algo similar?

La imagen 3 muestra mi intento usando copiar paralelo manualmente por atributo seleccionado, pero el resultado no es lo que esperaba, y desafortunadamente Copiar paralelo no puede añadirse a un ModelBuilder.

Muchas gracias

Hi Dorelia,

Thank you for sharing more details about the question. I think this is more towards a CAD or visualization workflow or format of the data on the map. Unfortunately, we don't have an Out-of-the-box editing tool that could generate this visualization.

But I have come across these use cases before and here are some of the workflow or options our users have tried.

Use Multi-Line Symbology

Add additional symbol layers to represent the visualization of the ducts
Pros - Simple and easy to create
Cons - Only one feature being created, so all the data records are maintained within one row

Use Copy Parallel and edit the last vertice

Use the "Copy Parallel" tool from the editing toolbox and generate the lines
Then use the "edit vertice" tool to modify the end of the line
Pros - Efficient creation of the parall lines at batch with a defined offset, each line is a separate feature
Cons - Still need to edit the end vertice to achieve the final visualization

Use Trace Tool and control offset during an editing session

This is the most common editing workflow I have seen from our users, but it is also the most manual workflow.
Will start from the point and draw a short line to the offset location
Then change the editing tool to "Trace", and click "O" from the keyboard to call out the "Trace Option", set the offset distance and other settings before completing the trace.
Repeat the same process at the end of the line to add the vertice to close the line at the endpoint.
Pros - The editor will have full control of the data creation, every line is also a separate feature
Cons - No batch processing, time-consuming.

Out of the three common workflows, I would highly recommend Option 2 since it is much more efficient and you can focus on the editing at the merging point all at once.

Hopefully, these options are helpful for you.

Thank you very much Jun Jie-Ma,

I understand what you mean and I also think Option 2 remains the better solution.

Is there a group/mailing list to receive updates on the new capabilities of the Network Management? Or it´s roadmap for the next few releases? Maybe this type of ducts visualization will be available one day.

Once again thank you for your time and kindest regards,

Hello Jun Jie-Ma,

first of all I would like to thank you for your detailed answer, in fact I have checked all the links you advised me to read and found it very interesting. However, I need to ask you a professional opinion, it might help me further.

I have received a .lpk with 2 layers of my interest Schutzrohr (cladding ducts in blue) and Stammverband (feeder ducts in red). You can see in pic 1 and 2 that these look perfectly symmetric, as if they have been generated by a tool similar to copy parallel. But how do you think they have achieved this effect of "confluence" to a single point, in this case a connection point. I measure it out and it really doesn't seem to have been drawn by hand, it is far too perfect.

The wired thing is that I have been told this was obtained with ArcGIS, and obviously didn´t tell me how. I am just braking my head there!

Any ideas? Does any tool in the Network management solve this? Or any tool at all?

I really thank you in advance and look forward to your replay.

Kindest regards,

D.Z

Hi Dorelia,

Thank you for your post and it is a common question that we get asked regarding creating offset lines for utilities and telecom cables.

I did check out your pictures for the testing and you are getting very close to making it perfect. I would suggest you to continue adjust the parameters within the tool to achieve what you want from the other fiber planning tool. Please see my attempt below:

And you are right, the "Copy Parallel" tool is currently not available through ArcPy or Modelbuilider. But we do have a technical document explaining how to complete a similar workflow with a customized script. (See Technical Document).
