In this routine, I intend it to be converted the region into a pline

but intend at the same time be preserved region.

Thanks.

Insert

 

(command "copy" ename "" "d" '(0 0 0))

 

Prior to

 

(command "_.explode" ename)

[marko_ribar]

And change

(command "_.explode" ename)

 

To

(command "_.explode" (entlast))

 

So that picked entity remains intact and operations that follow are performed on copy of picked REGION entity...

You may also want to look into PEDITACCEPT. If PEDITACCEPT is set to one this function will fail.

 

Maybe you should get the old value of PEDITACCEPT then set it to zero and at the end set it back to the old PEDITACCEPT. The same way you do it with CMDECHO.

Thanks!

 

Results , but the polyline is represented alongside displaced . I intend that overlaps the region .
