Unable to delete..Anything.

So, I noticed this problem yesterday when trying to delete some old viewports. I had to either use the 'erase' command or ctrl X to remove them. I ended up just turning them off. It was a mad rush at the time, so thought little of it.

Anyway, I am doing some drawing this morning and have some polylines I was going to delete. So I select, click the 'delete' button which has always worked. But nada. I can't think for the life of me whats going on here. Any clues?

Are the polylines on a layer called Defpoints or are they on a locked layer?

Maybe it is a system variable problem. Have you changed any lately? Used any custom LISP routines lately?

No, they are not on locked layers or in defpoint. In fact, I can't even change selected objects, lines, etc from 1 layer to another usign the drop down layer menu either, I have to open properties and do it from there.

I have been changing insunits, lt scale, set laylockfadectl value differently..and thats about the only variables I have toggled with before this started happening. I have also been changing the variable for 'annoallvisible' to 1 so my text appears in layout. (the standard drawing sheets in the office have not been tested very rigorously... >

I'm thinking it is a variable issue, but which one, I don't know. Thanks for your swift reply.

Is there a table in the drawing?

The following is to be considered a long shot but....

Select all. Delete everything. Use the "OOPS" command.

The above was posted at the AUGI Forums. Worth a try.

Set PICKFIRST TO 1

Set PICKFIRST TO 1

You are legend!

Does this variable reset to 0 then? Seeing as I have never used it before, I continue to be amused by autocad's many strange happenings, though I'm sure they have a some sort of logic to them.

p.s I also meant to just say, 'Yes, that worked. Thank you'

No variable should change on its own. There are some lisp routines that will change a variable and then set it back at the end, but if one cancels in the middle of it running the variable will be left changed. The lisp routines should have a built in error trap to change any changed variables back in the event of a user cancel, but many do not.

You are welcome, glad it worked.

That's twice now I've talked myself out of posting "Try setting PICKFIRST=1". I keep thinking, "It can't be that simple!" Duh. Guess I'll go put on the pointy hat and sit in the corner for 10 minutes. LOL

I came here looking for solution to another problem but was reading through the recent entries.

When I read the solution here it was like a 2x4 to the head. Fixed my problem, too.

It's the 4th or 5th time my ACad has reset Pickfirst all by itself (or, at least, unbeknownst to me) and I had but to read it to remember that this is what usually works for me.

I'm going to make a small note on my monitor that says, "Set Pickfirst to 1"

Thanks for all the help.
