[image] Is there a way i can change this curve to a polyline?

Hi, What’s the idea? You need to clarify more or share the .dyn so we can help you.

[image] i have two points like this on my 2 different alignments. First i want to create lines joining these points and then extend the line on either side by 3-4m. Then i will create the offset alignments on either side of my 2 main alignments. Those offset alignments will intersect somewhere wit…

Can you share a sample dwg too ?

You can convert your alignment to polycurve and work with it; [image]

[image] The problem is not with alignment. The problem is with the lines. I am using above node to get the intersections of alignment with curve lines. But i am not getting that since the “object” input in this node does not support curves, so I wanted to convert curve line into polyline so that it…

In your case,I’ll use Geometry.intersect to get that intersection Point. [image]

Thank you @A.C3D , it works. I have one more doubt. I want to create a polygon using four points. [image] I have these points in four different lists which looks like this. [image] I want to create a list which has different list in it each having 4 points taken from four separate initial lists…

fortunately, this issue is being resolved and i am able to create the polygons. [image] Now the issue is that even though 4 polygons are being created here in script, i don’t see any of them in my drawing. Test_Design File.dwg - Google Drive sample script.dyn (134.5 KB) I am sharing dwg sample…

The Polygon is still just an Object inside of Dynamo. To get it to the DWG-drawing you need a node to create an object inside of Civil 3D. Try using this node instead of the Polygon node, Polyline.ByPoints. [image]

Hola Amigos buenas. @A.C3D @ritesh.trivedi885J6 before to run learn to walk, make your baby steps first begin reading the hand book, to learn the dynamo Core and other resources first.

and for last read also the specialized threads for Civil3DToolKit, Camber, and Arkance Systems, i hope this helps you and good look!!
