hello,
excuse ,my english is not perfect .
I try to rebuild same kinds of entities cut "lines *polylines or arcs" from a windows selection .The form entities (coplanar) are deleted and replaced by a single.
I enclose for example this routine ,it works by Two Entities selection.
(this lisp wasn't made by me).
thank for your help

I enclose also another lisp, which only works for lines , but it's the type of selection what I want .
