.NET - Find COG of linear elem

Interesting, im getting 2 different point locations for the polylines, but for the exploded lines i get the same location for the point

When I run it here I can only get the point on the right. I’m not sure why the point on the left would appear unless some of the geometry is not being processed correctly. Given the left shift, I assume some additional geometry is included left of center, or some geometry is being missed right of center.

I won’t have any more time tonight but will take another peak at the situation tomorrow morning.

Ah yes, there was a bug. One of my steps was out of sequence and allowed processing geometry twice given a multiple crossing window selections.

The first post has been updated with the corrected code.

The selection process was not very user friendly in the original; I modified it a bit for a more AutoCAD like feel.

Modified source code is available if necessary.

OMG C# ....breath deep, its really just VB with some curly things {}.....and
and the comments are like C/C++

Nice Job Sean! I can see we have some Naval Architects / boat builders here and that is awesome!

I'm trying to load the dll file but something is going wrong. Can someone help me out?

This is what i get:

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value
[HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure
logging.
To turn this feature off, remove the registry value
[HKLM\Software\Microsoft\Fusion!EnableLog].

Thanx in advance
