Selectionpreview problems

Anonymous — Mon, 07 Dec 2015 16:04:27 GMT

Hi, I'm having problems with Autocad 2016 selection preview variable. I don't like to have it on, but every time i set it as 0 it ends up restting to 3 after a while. I have been trying to determine the issue, but so far i have no clues. It's definitely not Ctrl+Z. I aslo re-installed the product but it's the same. It's driving me mad! Anyone knows how to fix this? Thanks

Run the SysVarMonitor command.

Change your preferred setting of SELECTIONPREVIEW or add it to the list if it's not there. That will at least give you a clue as to what is changing it.

Thanks for replying. What do you mean with "add it to the list"? What list? I had already unticked the SELECTIONPREVIEW boxes many times, but it always rests and when I check the option panel the are ticked again.

The list of system variables that this tool monitors.

So do you have it set to 0 in there?

If so, when it changes to 3, you should get a bubble like this (if "Enable balloon notification" is checked on)

Then when you go back into the SysVarMonitor, it should look something like this:

So.....when this happens, go back and see what you were doing at the moment it changed.

Running some command?

Running a lisp file?

Narrow it down to whatever is causing it to change and eliminate it.

Another alternative is to use an autolisp reactor to prevent the variable from changing. See this for more details. You'll just reset the variable instead of displaying an alert box as in that example.

Hey, thanks I hadn't thought about this. I noticed my preferred value for selection preview was 3 so I changed it to 0 and I turned on the notification just in case it resets again, but i think that was that was the problem. I'll tell you later whether i still have problems. Thanks!
