You need to get the selection tag of the object.

First get the first tag.
Then get through all tags with GetNext() and check if it is a PointSelectionTag.

Sth like (pseudocode) :

var found = FALSE;  
var tag = obj->GetFirstTag(); if(!tag) return;  
while(tag!=NULL) //or tag!=DA_NIL  
{  
    if(tag->GetType()==PointSelectionTag){  
       found = TRUE;  
       break;  
    }  
    tag = tag->GetNext();  
}  
if(!found) return;

if found is true, the tag is a pointselection tag. you can now get the selected points and go through the point array.

var sel = tag->GetSelection(); if(!sel) return;  
  
var i;  
for (i = 0; i < obj->GetPointCount(); i++)  
{  
if (select->IsSelected(i))  
{  
    //This is the point position  
    var p = obj->GetPoint(i);  
}  
}

the mirror axis is the position of the symmtry object.
Get it from the global matrix:

var m = obj->GetMg();  
var m_axis = m->GetV0();
