Create Center line Between polygons

[mrmonemi]

Hello my dears:

in attached file I pose a problem,
I want draw center line (polyline) between the exist polygons,
regardless of how they connect in start point and end point.
Unfortunately, I search in internet but do't got the results
Except in ArcGIS-Esri Software
Is in the map3d software can be draw centerline like ArcGIS-Esri (Collapse Dual Lines To Centerline) or need to code
I am grateful guide

No it isn't posible. http://www.cadtutor.net/forum/showth...tween-polygons

I think it is possible. I would first use the Marins equations to solve for the centroid of each polygon and then solve for the centroid of each pair or the system of polygons.

Hi peter:
To obtain the center of gravity of a polygon can be use "map 3d=> topology=> polygon"
Perhaps this is the amount of work faster

I was talking about vanilla AutoCAD.
I was referring to developing the section properties for the polygon directly using lisp.

You could also copy and convert the polygon to a region and get the centroid property.

yes
it's better
