Problem with explode of Blockreference in Autocad 2010

Anonymous — Wed, 03 Jun 2009 06:55:37 GMT

Hi, everyone.
I found a strange bug in Autocad 2010.
The problem is:
In Autocad 2010 i'm creating a Blockreference that consists of a polyline with a ConstantWidth = 2.
After that, in my .NET source code, i'm trying to explode this Blockreference, as a result i'm receving a polyline, but when i'm trying to get its ConstantWidth value, i get - :[Autodesk.AutoCAD.Runtime.Exception] = {"eInvalidInput"}.
The same code written in ObjectARX C++ returns 0.
I tried to do this in Autocad 2008, and everything worked fine there. Is this a bug? Or is there some other ways to recieve, a constandwidth.
Thanks.

Here is some code sample:
{code}
PromptSelectionResult result = Utility.Editor.GetSelection();
if (result.Status == PromptStatus.OK)
{
SelectionSet set = result.Value;
Transaction tr = null;
foreach (ObjectId id in set.GetObjectIds())
{
Entity ent = Utility.OpenEntity(id, OpenMode.ForWrite, ref tr);
if (ent.GetType() == typeof(BlockReference))
{
BlockReference blockref = (BlockReference)ent;
BlockReference blCopy = (BlockReference)blockref.Clone();
DBObjectCollection objs = new DBObjectCollection();
blCopy.Explode(objs);
foreach (DBObject obj in objs)
{
Entity explodeEnt = (Entity)obj;
if (explodeEnt.GetType() == typeof(Polyline))
{
Polyline pl = (Polyline)explodeEnt;
try
{
double dwidth = pl.ConstantWidth;
}
catch (System.Exception ex)
{
Utility.ShowAfxBox(ex);
return;
}
}
}
}
}
}
{code}

Your code isn't easily readable in a newsreader.

Try posting it in an attachment. A sample DWG that shows the problem would
also help.
