How to trim objects quickly

When you trim objects, the first prompt asks you for a cutting edge. Gerardo Martinez e-mailed me a reminder that you can press Enter (or right-click, depending on your right-click settings) to specify all objects as potential cutting edges.

Then you just select the part of the object that you want to trim and AutoCAD automatically trims it at the closest possible cutting edge.

So remember:

  1. Start the TRIM command
  2. At the Select cutting edges … Select objects or <select all>: prompt, press Enter.
  3. Select the object(s) to trim.

There’s another shortcut for trimming objects—the EXTRIM command. EXTRIM lets you choose an object and then one side of the object. Here are the steps:

  1. Type extrim on the command line.
  2. At the Pick a POLYLINE, LINE, CIRCLE, ARC, ELLIPSE, IMAGE or TEXT for cutting edge: prompt, select one of the listed objects.
  3. At the Specify the side to trim on: prompt, pick on one side of the selected object.

    Start the TRIM command
    Enter twice
    Anything is trimmable as long as it intersects

  • admin

    Actually, using the Trim’s Extend option, you can trim objects that don’t intersect, but would intersect if the cutting edge were extended.

  • Cliff Turne

    For Trimming, if you select a polyline as the cutting edge,then Enter, if you pick any segment of that Polyline, that segment will disappear. The Polyline can trim itself!

    i tried extrim in autocad2012 there is no command with this name

  • admin

    That’s strange–it works for me. I tested it in 2012 and just checked again. You tried typing it on the command line?

  • Ganesh Shetty

    Yes Admin is right ,May be He Typed Wrong word in Command Line
    @saber Check your software properly (extrim works with Express Tools)

  • Megan

    How do you unblock blocked objects so they can be trimmed?

  • Ellen

    If you have any recent version of AutoCAD, you can open it in the Block Editor (BEDIT) and trim it there.

  • Rox

    To trim and extend any lines to any lines in a drawing (and have that set as the permanent default), type EDGEMODE in at the command line and set the value to 1.

  • I need to trim several objects inside different polygons, can anyone tell me if that is possible? i started using MAPTRIM but it only let me select one polygon at a time and i have thousands of them. i’ll appreciate the help :)

    you can also use the shortcut for trim. you just have to type tr…then select the edges then enter…..then select the line that you want to trim!

    how to trim 3d walls?

  • Peter in Cumbria

    There appears to be no EXTRIM in LT
    But using trim and select all works – and will save me hours selecting each line individually

    Thanks!

    @gerardo g martinez

    Thanks Gerado….that’s a real neat tip.

  • MongoGrubb

    I love this command and have a problem with it bogging down due to lack of a local file on my hard drive (it is remote located on a server a state away.) Is there any way to make it work faster in this scenario beyond going to a document management software?

    Thanks,

  • Adam Flaw

    What happened with the EXTRIM command with the 2014 Autocad? When I type in this command it comes back unknown command?
