Problem with selection boxes.

[Fritz]

In using AutoCAD today I had a strange problem pop up that I've never had before. I think it might be some setting that I accidentally change somehow.

 

It used to be that whenever selecting multiple objects, via window selection, crossing selection, or simply clicking on an object, if I then wanted to add objects to that initial selection all I had to do was draw another window or click on another object. Now suddenly, whenever I attempt to add objects to a selection, my initial selection becomes deselected. The only way now to add objects is to hold down the shift key. Additionally, if I attempt to add objects using the shift key and I accidentally draw my selection box wrong so it doesn't quite hit the object (working fast, you know how it is), then it deselects everything and I have to start over. This has become extremely frustrating for me in the short time I've had this problem occurring. I consulted the help file, which failed to live up to it's title. Does anyone here know why this is happening or how to fix it?

Pickadd=1

or Options > Selection > Use Shift to add to selection (uncheck)

these are the options you want

Thank you! I actually solved the problem myself only seconds ago via the nifty little "Similar Threads" tool 'ere. I wonder how I accidentally turned pickadd off?

you probably didnt.....it gets turned off ever-so-often if you fatal out, or certain commands will actually change your variables without you knowing...i call it a glitch..but it happens enough that I remember to check them all often....make sure to write down on a sticky note "PICKADD=1"

I call it poor lisp programming.

 

The reason this question gets asked so often is because of all the lisp routines floating around in cyberspace without proper error checking or resetting of changed variables.

 

If your variables are constantly being reset, it's a pretty good bet that a poorly written lisp routine is to blame. :wink:
