Select odd and elevation polylines

[ccd]

In the topography there are Major, Minor contour lines. I want to separate the odd contour elevation lines and even contour elevation lines.

Is there any way to do that in AUTOCAD.

Without knowing what major and minor object properties exist an answer would be difficult. If plines and have an Elevation, if a 3dpoly then have a Z.

 

 

Post a sample dwg.

 

Also welcome aboard.
