Select your desired cutting edge line.

Tipster Eng Cheong shows us a trick when trimming overlapping lines in AutoCAD.

"When you want to trim a line that is overlapping say, a rectangle, but this line is located behind the object, then you are likely to select the item in front by mistake. Use the command Bring to Front (DrawOrder) to bring it to the front before trimming it.

"There is also a sequence you can use to skip that step and go straight to the trimming:

  1. Select the rectangle as the cutting element
  2. Use a crossing polygon to select both the overlapping line and the rectangle (cutting element)
  3. Now you're finished: The line has been trimmed, but the cutting element has not."

Notes from Cadalyst Tip Patrol: The Trim command is a classic tool in AutoCAD. It cuts selected lines at a cutting edge line. Start the command, select the cutting edge line (or lines), then pick the lines you want to trim. You can select more than one cutting edge line at a time. In this tip, the user is faced with overlapping lines, making it difficult to pick the proper cutting edge line. As the tipster suggests, you can get around this by picking them all. You can trim an object to more than one line during your command; just keep picking the line to be trimmed until it is trimmed enough.

First things first. Use Overkill to remove overlapping lines in the first place. Unless they are phasing-based linework, then use layer states to control on/off when drafting.

Ctrl+Left click on the overlapping area to activate the object cycle . Once command line says <Cycle On> release CTRL and continue to cycle the objects with the left mouse button.

In reference to the second suggestion above, for selecting one from several overlapping objects, I believe the command to cycle through the selections is now; Hold SHIFT & SPACEBAR; Left-Pick on the pile of objects, then Left-Pick in space to cycle among them. Right-Click to select the currently highlighted one. I got really annoyed with Autodesk when they made this command more complicated; I find it very useful. Another handy thing about Trim which took me years to catch on to is using "F" (fence) for object selection. You get a list of options you might not have thought about by typing a "?" at the prompt. (I dunno why it took me so long...)
