cannot toggle between objects when trimming

[Anonymous]

ctrl + spacebar does not toggle between stacked objects while trimming. I am unable to trim lines and hatches that are underneath other lines. The only way to trim the line in question is to trim every single line that is stacked on top of each other. This was never the case in CAD 2009 and i am having non stop issues getting CAD 2015 to act in a productive manner. Any help would be appreciated.

Turn on Selection Cycling, one way is the icon at the bottom of the screen to the middle right, is 2014 and using letters it will show SC.  Toggle that on and then try trimming.

The behavior has changed a few times in recent years.  Try Shift + Space + Left Click  (look for <Cycle On> in the command line)

I already have selection cycling turned on. the shift + spacebar ( i mistyped when i mentioned ctrl earlier) has been working fine until i decide to use it during the trim command. i assume its the same way with other commands as well but its the trim command that i use most often. very odd that it would only work when there is no commands active.

Selection Cycling in AutoCAD2015 doesn't work for me in certain situations where it did work in previous versions. I haven't yet determined if it's a problem with 2015, or whether it's due to a setting(s).  For example, when using TRIM in 2015, SC works fine for selecting the cutting edges, but it doesn't do anything when there are multiple objects to be trimmed.  Ditto for MATCHPROP, it works for selecting the source object, but not the destination object(s)

@Anonymous  are you able to cycle through objects using Shift + <space> + Left Click?

The problem with Selection Cycling seems to be tied to the new COMMANDPREVIEW variable.  When COMMANDPREVIEW is disabled, SC can be used within the Trim command to select the object(s) to be trimmed,

just as you said, i can toggle between stacked objects when there is no command active but as soon as i attempt to trim... well it decides not to toggle between objects that are stacked on top of one another. hopefully this can get fixed soon. The only way i see to get around my little issue is to trim everything that may be stacked and then redraw what i didnt want to get trimmed. time consuming and frustrateing to say the least.

so that worked brilliantly! thanks for the help nestly2. much appreciated

I'm having the same problem in CAD 2015. Selection Cycling is turned on and is set to '2'. My understanding is that this should turn on the Selection Cycling Listbox (the mini pop up box that used to list the elements that were overlayed on each other which allowed you to pick which one you wanted to perform the command on, like trim). But for some reason my Listbox does not appear even when set on '2'. I checked my Drafting Settings and the checkbox is marked for the Listbox, so I'm not sure what's going on with this. Anyone have any thoughts as to how to get my Listbox showing again? I kinda prefer that over the Shift+Spacebar method. Thanks

Ah, you guys are faster than I can post. Thanks, that solved it for me

It solves my problem too! Love it!!!

Hi gguevarra,

I've got the same problem.

My List Box just does not appear. Did you find a way to fix it?

Are you using autocad for win or mac?

Thanks,

Jonas

I am having this same problem in 2016. The keystrokes above look like this:

Shift + Space + Left Click

<Cycle On> <Cycle Off>

Any idea why it would automatically Cycle off??

And, changing these settings turns off Command preview, which enables Selection Cycling suring the command...But, acually selection cycling has some "added features"

Example: I have two lines overlapping. I want to extent one of them to an arc. When using Shift-Spacebar, instead of Selection cycling I have the option to trim during the extend command. With Command preview off, the display changes, but not the behaivior so the result is an UNEXPECTED (unpreviewed) trim instead of extend.

Clear as mud?
