How to create feature lines from objects (alignments) using the C# API

daniel_rosell_moreno — Mon, 17 Apr 2023 08:20:36 GMT

Good morning, I've been trying to do this for a while now but I haven't been able to do it.
The idea is that given a list of alignments, convert each of them into a dynamic feature line.
From the interface it is very easy, in home, click "Feature line">"Create Feature Lines from Alignment".

I look forward to your responses and thanks in advance.

HI ... TRY

1-GET Polyline FROM Alignment WITH GetPolyline

2- Creates a FeatureLine from the Polyline WITH Create(String, ObjectId)

3- Set an elevation to existing Feature Point FROM profile WITH SetPointElevation

4- Inserts a PI point along the FeatureLine FROM (profile entities WITH Entities ) WITH InsertPIPoint

Sorry, I don't explain myself well.
What I have is an alignment, with several profiles.
What I want is to make a characteristic line using one of the profiles of said alignment.
Mention that it is very important that the new characteristic line is dynamic.
Anyway thanks for your answer.

I have this alignment:

And the steps I follow to create the characteristic line are the following:

Try @daniel_rosell_moreno

Get ngl profile

Change this line

(prof.ProfileType == ProfileType.FG)

Here's one way ... code by @Jeff_M @

// https://forums.autodesk.com/t5/civil-3d-customization/get-the-design-profile/m-p/10080874 public ObjectId GetDesignProfile(Alignment align) { var retval = ObjectId.Null; foreach(ObjectId id in align.GetProfileIds()) { var prof = (Profile)id.Open(OpenMode.ForRead); if (prof.ProfileType == ProfileType.FG) retval = id; prof.Close(); if (retval != ObjectId.Null) break; } return retval; }

Ok thanks, I already have the profile with which I want to make the characteristic line. But my doubt is how to create the feature line
