Methods of sample line groups and sample lines

[denes.nagy]

Hi,
I’d like to use methods belonging to sample line groups and sample lines in python, but I don’t know how can I reference my existing sample line groups and sample lines. Can someone help me out with an example?

What have you tried so far? Please share your work.

Not much. I tried to refer the generated samle line group, by querying it’s ID with “Alignment. GetSampleLineGroupIds” method, but with the ID I couldn’t use the methods of SampleLineGroup Class. I think I need to refer that object another way.

This script only generates the group and the samle lines.

You can use dynamo SL or SLG nodes as input, then you can access the InternalObjectId and you have to open the object using that id.

How can i create Multiple Section View Using Civil 3D Dynamo Python Script?

Hi, There are some nodes in Camber, Arkance and C3DToolkit packages, but I don’t know their limitations. Last year I tested section view group creation, but I did not get it to production, so use it with caution. It should create section view group for every input sample line groups. It is also made for specific template, so you have to modify style names in the code. As I said it is not complete, not well tested, so bugs may occur, i.e. source selection. (see video) That said here is the …

Some way to add sample sources with Dynamo in Civil 3D?

Sorry, I missed the part that you wanted to add surfaces. # Load the Python Standard and DesignScript Libraries import sys import clr # Add Assemblies for AutoCAD and Civil3D clr.AddReference('AcMgd') clr.AddReference('AcCoreMgd') clr.AddReference('AcDbMgd') clr.AddReference('AecBaseMgd') clr.AddReference('AecPropDataMgd') clr.AddReference('AeccDbMgd') # Import references from AutoCAD from Autodesk.AutoCAD.Runtime import * from Autodesk.AutoCAD.ApplicationServices import * from Autodesk.AutoC…

Yes, thanks for the tip, but I want to reach the new objects during the same script running. So I want to refer somehow the newly generateg sample line group in the python editor. Is it possible?

When you create the SLG the Create () Method should return the SLG ObjectId, so you should be able to use that.
