I cannot deselect multiple lines at a time using shift.

[Anonymous]

Normally I can select lines, and if I selected too many i can hold shift, and draw a window to deselect. Now when I do it only one line deselects at a time. I've checked my PICKADD and other related settings, they do not help. I'm using autocad 2013

It has to be a crossing window and not a window, unless you window the entire line.

Do you mean "windowing" no longer becomes an option when you hold SHIFT down to deselect?

Are you sure they are not deselecting? GRIPS can stay on if shared with other objects touching at those point.

How I'm doing the window is not the issue, yes it is a crossing window, and it still lets me use the window after I hold shift. The problem is only one line will deselect at a time, rather than everthing crossing through the window.

Any other ideas? I've found other people online with the same issue, but i've found no solutions that work for me.

Are you using Civil3D, P&ID, or any add ons like Raster Design?  Is this a plain vanilla version of AutoCAD in other words.

What are your settings in the "selection" tab of the OPTIONS dialog box set to?  They should look like this by default:

It could be the software just became corrupted.  Try runing a repair on the software (Control Panel > Programs and Features > right click on AutoCAD > Uninstall/Change > Repair).

Unless we can recreate the problem, there is no answer: does this happen in ALL files? Can you post a video showing us how it's failing for you? Autodesk has a freeware called SCREENCAST to do so.

[jporter]

Good point, Dean!  Does this happen in all drawings?  That's important to know.

It has the program microvellum installed, but otherwise is vanilla. It happens in all drawings. I can get a video of it, but there isn't much to see. It looks exactly like a regular shift-select except only one line or object deselects at a time. What weird is group selection is on, but it deselects lines from within the group. Here is a screenshot of my settings: http://imgur.com/7u5A7B9

last link is broken for some reason, here is the settings. http://imgur.com/AL0Jbvw

If you run AutoCAD without Microvellum (you must have a profile startup that does so), does the problem go away?

[Anonymous]

I'm not sure how to create a profile that starts up without it, I can turn it off after its started, or just turn it off at microvellums splash screen. I don't beleive microvellum is the issue. It has no options related to selection I know of, except for turning grouping on and off, and I've had no issues with it for the 8 months I've had it. I've not changed anything I can think of recently, perhaps one of autocads frequent crashes caused it?

First try a repair on the software.  There are two ways to do this. . .one, through the Windows Cotrol Panel > Programs and Features > select AutocAD  > right-click and select Uninstall or Change > select repair. . .two, Windows start button >  All Programs > Autodesk > AutoCAD _____ > Reset settings to default. 

If that doesn't work then it could be a Windows update that triggered something.  Try restorinig your system back to a time when you know it was working.  If it works then we know that there was a Windows update that is screwing with your software.  

System Restore Point

I don't think it would be a good idea to try those as they could create issues with the other software. Is there a way to try fixing it that won't change settings all at once? I may as well reinstall both programs if those are my only options.

[jporter]

The system restore point won't affect the software negatively.  It will only restore the settings to the way they were prior to the break.  It doesn't affect your files.  

If you don't want to do that then the only other option would be to uninstall both software.  Then install only AutoCAD and test to see if it works.  Then install Microvellum and see if it still works.  

However, if it's a Windows related issue then it might pop up again in the near future.

I recently had this exact problem in Civil 3D 2015.  I could crossing select a group of objects, but couldn't deselect them by shift crossing the ones I didn't want.  I finally figured out that an underlayed pdf was the problem.  

I had xreferenced in a pdf to my base, as a quick way to start the drawing.  After drawing over the top to match, I unloaded the pdf, in case I needed it in the future.  That's when Acad began not doing what I wanted.  Window selecting a certain group of lines and hatches and then pressing shift normally gives me the deselect function, and hovering over a selected object shows a - symbol that means I will get what I want.  

As soon as I detached the underlayed pdf, acad began functioning as I am used to.  

Not sure this is an answer to the OP, but it was the solution to my specific problem.

James,

That's definitely a possiblity.  Whenever you click within the border of the PDF you are actually selecting the PDF.  I think this is a new feature.  I'm not sure, but I could have sworn that in earlier releases the only way to select a PDF was to select the border.  

Good to know though,

This is also a problem with 2020.  If you are selecting lots of lines over and over again eventually you are unable to deselect the lines and have to regen to clear the selection, close the drawing and go back in.  This was also a bug in 2018 as well.
