Loft tool creates extra side line

Hi everyone,

 

I'm new to Autocad but trying to learn it. I'm using Autocad 2011 and trying to convert a 2D drawing into 3D using a Loft tool. However, I'm experiencing a bit of a problem. The Loft tool is creating an extra line between the two objects which messes up part of the design. I'm usind Solid and Ruled settings of the Loft tool and the two object I'm trying to join were created out of number of polylines which then were converted into singular poline using Edit Polyline tool. I cannot figure out what the problem is.  

 

I've attached two pdf files which hopefully will help you to see my problem. 

 

Thank you in advance for your help. 

Hi,

 

AutoCAD has to find connections between the two polylines, so for every vertex in one section there has to be found the best suitable vertex in the opposite contour. And with that number of vertices (you'll see it from top view) AutoCAD has troubles to get them around the full contour sorted perfectly.

What you should do: split your contours in regions, LOFT them and then you can UNIFY these back to one solid.

Hi,

Sorry, I even don't see the "extra line" in the amount of lines you have.

Upload your drawing with the two polylines so we can look into the geometry.

Here I added edited pdf showing the line and I also included the dwg file so you can see it in Autocad.
