Trimming problems

I have Autocad 2023.  I am trying to trim 44 lines using fence.  Only 10 lines trim to the boundaries then the rest get deleted.

Also, if a trim a line that has the boundary out of focus, it deletes the whole line.  I normally do not work in Autocad so I don't know what is going on.

 

The same is with extend.  If I extend many lines to a boundary using fence, only 10 will extend and the others will extend to the next boundary or not extend at all.

Ensure your AutoCAD commandline is 5-10-20 lines tall, then try those commands again: what is the program reporting is the problem? There is always an alert.

Perhaps not all the lines are drawn in same elevation. Maybe first run flatten command and then try trim fence again

All elements that are used as a cutting line have to be on screen, or else they get ignored and trimming cuts away the whole line (or polyline-segment to the next vertex).

This is done by AutoCAD for performance reasons - otherwise it could take a long time to check all elements of the drawing if they could be cutting lines.

 

Except - if you start the command TRIM, type C for cutting line*, select all lines (or other objects) you want to trim to,  enter and now you can trim your lines without having the cutting lines on screen.

* i have a german version - here it is S for "Schnittlinie" - i don't know if it is C (for cutting line..or edge?) in english.
