Integrate Dynamo with Autocad

[Yonas89]

Hello,

I am not sure which forum to choose for my question, thus I hope I have chosen the right one. I have read and watched about Dynamo compatibility with Revit and it looks just amazing. However I use Civil 3d in my daily process which is AutoCAD based and though it's  challenging  to combine Dynamo with AutoCAD, I know it's possible, but I don't know how. I would like to discuss with you guys, maybe you have some experience with it or some thoughts to share. I have found this short video here: https://www.youtube.com/watch?v=oiz76GTN-8Y. Sorry that it's in Russian, don't understand Russian but I get the point that AutoCAD objects could be controlled from Dynamo.

@KhasanMamaev

It is a question for you.

@Yonas89

You can ask @KhasanMamaev in PM about Dynamo & AutoCAD.

[KhasanMamaev]

Hello. You're right, Dynamo can integrate with AutoCAD. Say what you want to solve the problem and I'll show you a solution.

[Yonas89]

Hello, thanks a lot for tagging the author of the video. This is great.

Hello @KhasanMamaev, 

I do not have any specific task yet actually, I am just trying to understand the limits of Dynamo  implementation in civil engineering.  I think that Civil 3D with Subassembly composer is okay for making dynamic road. However I am thinking to use Dynamo for making some infrastructure elements such as intersections, roundabouts, driveways or culverts to make it parametric as much as possible.

Well, if you do not have a specific task, then I'll show you how to build the line in the open AutoCAD file.

restart = IN[0]
if IN[1] != True: off = 1/0

import clr

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

import System
from System import *

app = System.Runtime.InteropServices.Marshal.GetActiveObject("Autocad.Application")
AcDoc = app.ActiveDocument

lines = IN[2]

def ptA(p):
	return Array[float]([p.X, p.Y, p.Z]) 


for k in lines:
	stpt = ptA(k.StartPoint)
	enpt = ptA(k.EndPoint)
	linn = AcDoc.ModelSpace.AddLine(stpt, enpt)

This inverse problem. Get a dedicated line from AutoCAD

restart = IN[0]
if IN[1] != True: off = 1/0

import clr

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

import System
from System import *

DPoint = Autodesk.DesignScript.Geometry.Point
DLine = Autodesk.DesignScript.Geometry.Line

app = System.Runtime.InteropServices.Marshal.GetActiveObject("Autocad.Application")
AcDoc = app.ActiveDocument

def ptD(p):
	return DPoint.ByCoordinates(p[0],p[1],p[2])

def linD(p1,p2):
	return DLine.ByStartPointEndPoint(ptD(p1),ptD(p2))

sset = AcDoc.PickfirstSelectionSet
n = sset.Count

curvs = []
for i in range(n):
	if sset.Item(i).EntityName == "AcDbLine":
		stpt = sset.Item(i).StartPoint
		enpt = sset.Item(i).EndPoint
		lns = linD(stpt,enpt)
		curvs.append(lns)

OUT = curvs

Hi,

I can't find "ForceChildrensEval" on the web. Where can I find this or how can I make this in Dynamo?

[KhasanMamaev]

This node from Prorubim DS Common Kit package 

[Slawomir_]

Thanks! Is it free for commercial use?

[KhasanMamaev]

its free

[Slawomir_]

I'm stuck. Did complete sample You have shown but now I don't know how to display this Python text window.

Dynamo 0.9.1

[KhasanMamaev]

Double click to Python Script node

[Slawomir_]

It's working! Thanks a lot!

is it possible to import information from Excel to property set data in Autocad Architecture?

[Yonas89]

Hmm, I think with Dynamo it would be possible but difficult. I think the better option would be to create custum plugin for it.

[KhasanMamaev]

That's possible.

[KhasanMamaev]

Of course it would be good to write a plugin, but in what programming language? In Dynamo there are nodes to work with Excel, it is already good
