[image] Dynamo python export polyine and hatch to AutoCad Developers I didn’t find in Linkdwg a tool to export a polyline to AutoCAD that contains arcs, only polygon to polyline or polycruve to a bunch of separated lines and arcs. T1.dyn (26.0 KB) [T1_2020-06-07_09-17-47…

here a simple example without arc (no need to get bulges) [getBoundary hatch3] code IronPython import sys import clr import System from System import * clr.AddReference('ProtoGeometry') from Autodesk.DesignScript.Geometry import * from math import tan, radians from System import Array errorAcd = …

@Deniz_Maral you can use the Civil 3D Toolkit. [Capture]

Thank you very much for your reply! I forgot to mention that I use Dynamo for Revit. Is it still possible to use it? If yes, how can I select hatches?

Hello you can try to use GetLoopAt() method (Active X) https://help.autodesk.com/view/OARX/2020/ENU/?guid=GUID-93E21F08-C55A-4D56-9A3B-DEADB29838C0 or using this process (Active X) [image] AutoCAD Hatch Boundary by Layer So… it’s been one of those days… All I want i…

Hello Cyril, I tried that one but it opens AutoCAD and user has to select something. It would be nice to do it like in BiMorphNodes from @Thomas_Mahon I don’t have much experience in AutoCAD API but I will try to do something. A new chapter to learn something new :slight_smile:

Merci Cyril! I will try it tomorrow. Can you still get polylines if you delete them after creating hatch?

[image] Deniz_Maral: Can you still get polylines if you delete them after creating hatch? No, in this case need to use this method [image] AutoCAD Hatch Boundary by Layer So… it’s been one of those days… All I want is to grab the hatch in a dwg, grab it’s outline …

Merci Cyril, if I have to open AutoCAD via that Node then it would be better to use LISP and create those boundary curves. I thought, you can get element attributes of hatches like BiMorph gets curve attributes.

Boss @c.poupin , in some casses some versions of cad can not get AcDoc correctly may be because of API changes for some of cad versions , so what sohould i do to make your code work nicely with any version of cad. Your help will be appreciated, Thanks in advance.

Hi, you can try to find all progId from the registry then you can get the app with m_App = System.Runtime.InteropServices.Marshal.GetActiveObject(progId) example here https://adndevblog.typepad.com/manufacturing/2013/05/running-programmatically-a-specific-version-of-inventor.html
