Merge/split alignments

[bertrand.savarit]

Hello,

Does anyone have any idea how to merge two or more alignments in Dynamo?
Is it possible to create an empty alignement and then copy/paste all subentities from the alignements we want to merge?

Thanks for your help/ideas

Hi @bertrand.savarit,

Something like this? I’m only covering line and arc subentities in this example, but you could expand it to include spirals if you need.

Exactly! but for the spiral as we have to identify the previous entity in the alignement i’m facing the problem i described in my post here :

Create an alignement within Dynamo

Hello, I am working on a script that create an alignement depending of the geometry of a “master” alignement. My question is the following : In Civil 3D i can easily create a free spiral curve spiral between two lines that are not secant. [image] In Dynamo i can create my different straight lines but then just my first line is recognised as an entity of my alignement so i can not define the previous and next entity in my free spiralcurvespiral node [image] [image] I found a workaround …

hi @zachri.jensen
How can we split an alignment into two ?

Awesome graph. I was looking for the exact thing. Thanks.
One question: is there a way to consider in the merged alignment the station equation definition in one of the alignments? I have one alignment with several station equations and I’m trying to join another alignment at the end. Thank you again sir.

I’m sure there is, but I have not attempted something like that.
