Riamus2,
I have thought of that initially, and now that you have confirm the idea, i went ahead to do that.
Maybe my maths isnt good but I have a new problem (lol gawd)
See red circle area: 
As you can see, the hilight drawrect -d still remain visable after drawing the ellipse and covering unwanted areas with rectangle fills.
The following are the code (excuse basic coding, i always start basic before ii "clean up" into more complex coding.. its easier this way for me to keep track of everything
)
The Code: window -adk0opx +f @SME_MENU -1 -1
/drawfill -r $active $rgb(150,100,150) 0 1 1
/drawrect -rfd $active $rgb(100,100,100) 2 100 100 300 400 50 26
/drawrect -rd $active $rgb(0) 1 100 100 300 400 50 26
/drawrect -rd $active $rgb(200,200,200) 1 101 101 298 398 50 26
/drawline -r $active $rgb(50,50,50) 1 125 498 375 498
/drawline -r $active $rgb(50,50,50) 1 398 112 398 488
/drawrect -re $active $rgb(50,50,50) 1 349 473 50 26
/drawrect -rf $active $rgb(100,100,100) 1 345 470 34 28
/drawrect -rf $active $rgb(100,100,100) 1 379 470 19 14
