Selected Object Blurry Appearance

Anonymous — Fri, 23 Aug 2019 16:07:32 GMT

I've been using AutoCAD 2013 at work since it came out. When I upgraded to AutoCAD 2015, and now 2020, I observed that when entities are selected the highlighting changed from the dotted line approach to something like a neon tube. I am starting to have some issues with my eyes and this visualization method is kind of hard to look at as it makes selected entities look fat and blurry. I would like to know if there is a way to change this back to the method used in earlier versions.

Hey @Anonymous

Try setting the PRESELECTIONEFFECT system variable to 0

Hi,

if it's the color you want to change the system variable SELECTIONEFFECTCOLOR controls that.

You can also turn off SELECTIONEFFECT ... does that help better?

I just tried that and it didn't seem to have any effect. Do I have to close and restart the program perhaps?

Hi,

>> just tried that and it didn't seem to have any effect.

That should look very different, but it depends on hardware acceleration. by any chance, is your hardware acceleration disabled or does your graphic card run on DirectX9 instead of DirectX11 (to be controlled using command _GRAPHICSCONFIG).

I have never adjusted hardware acceleration or changed/updated directX. I am just looking for info on those actions and so far ACAD help is not helping. Will try looking on line.

OK, just checked hardware using the 3dconfig command and found it to be on but that I am using directX9. I will look for this on line as well.

That means either your graphic card is not compatible with DirectX11 (from AutoCAD's point of view) or you have used a workaround (for previous versions of AutoCAD) so AutoCAD just uses the older DirectX interface, maybe because you had troubles with the graphic card previously.

When you start command _GRAPHICSCONFIG ... can you show a screenshot from that dialog?

I am using a computer setup as a "CAD workstation" back in 2012. It is running win 7 and there have been no hardware or significant software upgrades since. I believe they are planning on upgrading to win 10 in the near future but don't know if that will affect this issue. My video card is an AMD Radeon HD 6670.

Since that's in response to @ian.mag who suggested changing only the PRESELECTIONEFFECT setting, make sure you also change the [plain-old] SELECTIONEFFECT setting, as @Alfred.NESWADBA added.

Yes, it will affect the whole situation as all drivers are then new (I hope Windows 10 will be installed from scratch and not as update from your existing Windows 7).

I also hope that Windows 10 is not installed on a workstation that is 7 years old. Some of your hardware will not be supported from Windows 10 (or only with some very generic drivers, that have then not a good performance).

Thank the gods, as simple a fix as one could hope for. and as nonintuitive as most things AutoCAD.

This was not a solution to my issue and I do not know how it was listed as one.

What exactly was the solution for you?

My apologies Alfred, it does look like you first posted the solution. I saw the selectioneffectcolor reference and missed your reference to selectioneffect. I noticed it when Kent mentioned it in post #10 and tried it which solved my problem. Also I hadn't personally indicated your posted reply #3 as a solution and was initially put off by it having showed up as one. I hope this clarifies things and I did like your reply. No hard feelings I hope.

Hi,

>> My apologies Alfred

Nothing to apology. 😉

>> I saw the selectioneffectcolor reference and missed

>> your reference to selectioneffect

That is what I saw ... SELECTIONEFFECT was the solution, so it was correct that (for future readers) post 3 is a valid solution?

Please un-select post 15 as solution as it isn't one (and people searching for solutions won't understand post 15 as one.
