HELP..Please

Hi all,

I am desperately looking for the function in Coreldraw that allows me to cut one object based on the intersection of another object.  Essentially I am looking for the "Trim" function that exists in Autocad.

Example...  draw a circle...then draw a line that crosses the center of the circle.  I want to be able to remove the bottom half of the circle below the intersection line.

OR

draw and long narrow ellipse...then draw a circle on top of the ellipse I want to remove the ends of the ellipse outside circle...

In autocad this takes exactly 3 keystrokes and less than 2 seconds...I have tried everything in Coreldraw and cannot find away to make this happen...

 

Thank you in advance.

James
