Get specific AutoCAD type properties

Civil3D
1

Hi. This planned script will need to handle a variety of different AutoCAD drawing object types. The selection set has DBTEXT, MTEXT, HATCH, POLYLINE and LINE objects. In this example, after verifying the selected object is a LIne, I need to get more Line properties. The StartPoint is not found, result is always 0,0,0 … what did I miss? Thx for your patience.

  # 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')

adoc = Application.DocumentManager.MdiActiveDocument
ed = adoc.Editor

def select_objects():
	
	global adoc
	global ed
	
	output = []
	
	with adoc.LockDocument():
		with adoc.Database as db:
			with db.TransactionManager.StartTransaction() as t:

				acSSPrompt = ed.GetSelection()
	
				if acSSPrompt.Status == PromptStatus.OK:
					acSSet = acSSPrompt.Value
					for s in acSSet:
						if s:
							obj = t.GetObject(s.ObjectId, OpenMode.ForRead)
							if type(obj) is Line:
							  L = Line(t.GetObject(s.ObjectId, OpenMode.ForRead))
							  output.append(L.StartPoint)
							else:
							  output.append("not")
							
				t.Commit()
	return output	

if IN[0] == True:
	OUT = select_objects()
else:
	OUT = "nothing"

hi
can you see Code
There is a different way

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.AutoCAD.EditorInput import *
from Autodesk.AutoCAD.DatabaseServices import *
from Autodesk.AutoCAD.Geometry import *

# Import references from Civil3D
from Autodesk.Civil.ApplicationServices import *
from Autodesk.Civil.DatabaseServices import *

# The inputs to this node will be stored as a list in the IN variables.
	
adoc = Application.DocumentManager.MdiActiveDocument
editor = adoc.Editor

with adoc.LockDocument():
	with adoc.Database as db:
		with db.TransactionManager.StartTransaction() as t:
			bt = t.GetObject(db.BlockTableId, OpenMode.ForWrite)
			btr = t.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite)
			tv = []
			errorReport = None
			for oid in btr:
				bl = t.GetObject(oid, OpenMode.ForRead)
				try:
					if isinstance(bl, DBText):
						tv.append(bl.TextString)
						
				# Catch and report Exception...	
				except:
					import traceback
					errorReport = traceback.format_exc()
					
			t.Commit()
           				

# Assign your output to the OUT variable.

if errorReport == None:
	OUT = tv#Text Values
else:
	OUT = errorReport

THANK YOU … THAMK YOU … THANK YOU … my code is working now!! and that’s with editor > select objects … the key to success was … isinstance … that solved it for me …
