Autocad 2022 Trim command

[coffeejeanpaul]

Good day, 

Using the new trim command, I do find it quit horrible, as it is trying to process and predict trim that I do not want ending in a result of AutoCAD crash.  Is there a way to switch the command back to the old trim?

Do you mean the trim command preview feature?

If that, turn it off with the COMMANDPREVIEW system variable (set it to 0).

If you want the old trim behavior, set TRIMEXTENDMODE system variable to 0.

Hi @coffeejeanpaul 

The trim command was given a new enhancement and it works a little different than how it was before. This change was got in version 2021 and many people complain about this enhancement. You can switch back to an older way of working with trim and extend by typing in the command "TRIMEXTENDMODE" and setting it to "0" 🙂

Thanks

Or when you start the Trim command, select Standard in the command bar, rather then having it set to quick.

thanks for this ...

If you want the old trim behavior, set TRIMEXTENDMODE system variable to 0.

Is there a way to have both new and old trim/extend commands....I like both for different purposes

You should create a LISP routine as shown above:

(defun C:TRO (/)                     ;Old trim
  (command "TRIMEXTENDMODE" "0")
  (command "TRIM")
  )

(defun C:TRN (/)                     ;New trim
  (command "TRIMEXTENDMODE" "1")
  (command "TRIM")
  )

I'm just trying to figure out how they spell enhancement...there is no way way they even tested the command we all use on the daily...bad job by you autodesk is an understatement

Before criticizing, you should realize that the old functionality is still there and just a setting for the command.

This setting back to the old mode did no work in 2022 version.  Is there another way to use the 2020 version for trim?

using a window selection then selecting what you want trim and not letting the computer do it.  If it's not broke then why do they think they fixed it.

[CherMcGettigan]

Why do we have to create a lisp for everything that is changed?  I don't get paid to create lisps.  I get paid to do my work.

[CherMcGettigan]

Trim Extend was not broke so why does Autodesk think this fixed it.  Also, change mode to 0 didin't work.  Guess I'll just use the break command.  Working from 2020 straight to 2022.  Ugh!  Losing my project hours with this.

You give up too easily.

If you mean changing TRIMEXTENDMODE didn't work, that's only one of the relevant System Variables.  It's about cutting-edge selection [new = automatically starts with everything selected; old = you had to hit Enter to tell it you wanted that].  But if you're talking about after cutting-edge selection, the previewing of what's going to be cut away if you pick on it:

I suspect that's the real topic of the original question, because of the wording "it is trying to process and predict trim that I do not want."  That's controlled by the COMMANDPREVIEW System Variable [see Message 2].  You may want one or the other or both of those System Variables set for the old way.
