Dynamo Autocad – Interop connection with C# – Part2

By Rami Hamati | .NET, Dynamo BIM | Comments are Closed | 5 January, 2019 | 0

Description In our previous article we have made a live connection with Autocad. We create a class called “AutocadConnection”. In this article we will query the document using a console application and we will print out some information regarding our open Autocad application. Code

class Program
    {
        static void Main(string[] args)
        {
            AutocadConnection Connection = new AutocadConnection();
            AcadApplication acApp = Connection.Application;
            
            if (acApp != null)
            {
                Console.WriteLine(acApp.Application.ActiveDocument.ActiveLayer.Name);
                Console.WriteLine(acApp.Name);
                Console.WriteLine(acApp.ActiveDocument.Name);
                Console.WriteLine(acApp.ActiveDocument.ModelSpace.Name);

                AcadLayouts layouts = acApp.ActiveDocument.Database.Layouts;
                IEnumerator enumerator = layouts.GetEnumerator();
                while (enumerator.MoveNext())
                {
                    Console.WriteLine($"Layout: {((AcadLayout)enumerator.Current).Name}");
                }

                AcadDocuments Documents = Connection.Application.Documents;
                var enumerator2 = Documents.GetEnumerator();
                while (enumerator2.MoveNext())
                {
                    Console.WriteLine($"Document : {((AcadDocument)enumerator2.Current).Name}");
                }
            }
       }
}

Dynamo Python – Dictionaries from python to graph

By Rami Hamati | .NET, Dynamo BIM | Comments are Closed | 8 December, 2018 | 0

Description Why ? Working with data requires a certain amount of organizing the data. Dictionaries are often and Dynamo provides two ways of making this. The first method would be to use the newly added support for dictionaries in Dynamo. The second method would be to use python dictionary if you make your workflow in python.Read more

Dynamo Python – Distribute lines along curve

By Rami Hamati | .NET, Dynamo BIM | Comments are Closed | 6 December, 2018 | 2

Description Perhaps not the most useful application in Dynamo however a pretty cool exercise. Line distribution along a polycurve is especially important when you want to determine the curvature degree along the curve for road projects. This exercise will open a door in that direction. Utilitary class (handles list checks and list unwrapping)

import clr
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *
import re
#utilitary

class utils:
	ul = [];
	def __init__(self):
		self.ul = [];
	def isIterable(self, unit):
		t1 = t2 = False;
		if(isinstance(unit, (tuple, set, list, dict))):
			t1 = True;
		if(hasattr(unit, "__iter__")):
			iterstr = str(unit.__iter__());
			if(re.search("System.Array", iterstr)):
				t2 = True;
		return (t1 or t2);
	def UnwrapList(self, list):
		self.ul = [];
		if(self.isIterable(list)):	
			self.UnwrapL(list);
			return self.ul;
		else:
			return list;
			
	def UnwrapL(self, unit):
		if(self.isIterable(unit)):
			for item in unit:
				self.UnwrapL(item);
		else:
			self.ul.append(unit);

ut = utils();

Dynamo Autocad – Interop connection with C#

By Rami Hamati | .NET, Dynamo BIM | Comments are Closed | 29 November, 2018 | 0

Description One of the major challenges while working in Dynamo was to retrieve data from external sources. While reading autocad files was somehow possible through external sources (sat exports, excel coordinate representation, etc) a live connection was not possible for a long time. At that time I found 2 methods to make a connection withRead more

Dynamo – WCF Basic Soap Service

By Rami Hamati | Dynamo BIM | Comments are Closed | 26 August, 2018 | 0

Description In this post I will show you how to create a simple WCF SOAP Service and consume it from Dynamo. These kind of services can be deployed on a server machine and be consumed by multiple dynamo users. You can design your most complicated algorithms and use a powerful machine to make the calculationsRead more

Dynamo – Database Sqlite Connection Model

By Rami Hamati | .NET, Dynamo BIM | Comments are Closed | 4 August, 2018 | 0

Description In the previous article (Dynamo – Database Sqlite Connection) I presented the .NET support for reading values from a Sqlite database connection. Although the approach is straight simple, a scalable and usable approach is as straight forward as that. In this article I will present a proper approach using models that stores database values. TheseRead more

Dynamo – Database Sqlite Connection

By Rami Hamati | .NET, Dynamo BIM | Comments are Closed | 22 July, 2018 | 0

Sqlite A database is a collection of information that is organized into rows, columns and tables, and it is indexed to make it easier to find relevant information. Data gets updated, expanded and deleted as new information is added. SQLite is an in-process library that implements a self-contained, zero-configuration, serverless, transactional SQL database engine. SQLiteRead more

Reading xml file with python in Dynamo

By Rami Hamati | .NET, Dynamo BIM | Comments are Closed | 24 June, 2018 | 3

System.Xml According to Microsoft’s link https://msdn.microsoft.com/en-us/library/system.xml(v=vs.110).aspx, this namespace provides standards base for processing XML. An important fact to know in Dynamo is that the version that it uses is IronPython (2.7x). While this may provide some disadvantages because a newer version of python would allow you to load numpy or other great python pacalges, there areRead more

Dynamo Python Tips

By Rami Hamati | .NET, Dynamo BIM | Comments are Closed | 10 June, 2018 | 1

Autodesk.Revit.DB Autodesk.Revit.DB is a namespace that is available to you in the python script node. With it you can access alot of functions for handling geometry and Reit elements like Arc, Circle, Area, Room, etc). The link to this namespace is http://www.revitapidocs.com/2017/87546ba7-461b-c646-cbb1-2cb8f5bff8b2.htm. Let’s say you want to create a Revit line. This is part of theRead more

Geometry Conversions in Dynamo with Python

By Rami Hamati | .NET, Dynamo BIM | Comments are Closed | 7 June, 2018 | 0

Definition Extension methods enable you to add methods to existing types without creating new derived type. Extension methods are static methods of a special type so that they are written in code as if they were part of the calling object’s class. In reality the compiler with generate the IL code like for a staticRead more
