phillyphantom Posted June 9, 2010 Share Posted June 9, 2010 I am having an annoying problem in AutoCAD 2010 that started when I got a new computer here at work running windows 7 - 64 bit. When I zoom in on a line drawn at an angle the line starts to change angle the farther I zoom in. The actual line doesn't change at all but it appears to on the screen. When I zoom back out everything is normal. I attached a few screen shots to help me explain. And there is no gap in between the lines as it doens't matter if I use snaps to connect lines. Picture 1 shows a angled line and a straight line that connect. Picture 2 - I have now zoomed in on the intersection and a gap appears due to the angled line changing. Picture 3 shows that when I select the area where the angeled line actually is, the line gets selected and shows up back in its correct spot as seen in Picture 4 Sorry if there is a thread on this somewhere as I didn't even know what to search for. Any help would be much appreciated. Quote Link to comment Share on other sites More sharing options...
ReMark Posted June 9, 2010 Share Posted June 9, 2010 We're looking at a 2D drawing? Are both lines at the same elevation? Quote Link to comment Share on other sites More sharing options...
phillyphantom Posted June 10, 2010 Author Share Posted June 10, 2010 yes both lines are drawn in 2D and are on the same elevation Quote Link to comment Share on other sites More sharing options...
Coosbaylumber Posted June 10, 2010 Share Posted June 10, 2010 I think much of this Viewing situation, has to do with what exact video driver and board is being used. Then on a secondary situation as to which exact OS is being used and the parameters about there. Wm. Quote Link to comment Share on other sites More sharing options...

ReMark Posted June 10, 2010 Share Posted June 10, 2010 Alright. Well I'm running AutoCAD 2010 as well at the moment. I'll have to see if I can duplicate the situation on my system. Quote Link to comment Share on other sites More sharing options...
MikeScott Posted June 10, 2010 Share Posted June 10, 2010 It's a regen issue.. check the REGENAUTO command and turn it on. If you regen when you're zoomed in, you'll see it repair itself. For some reason you're not automatically regenerating your drawing.. maybe due to a command running when you zoom in? Or possibly because of having the Regenauto setting to "off".

phillyphantom Posted June 10, 2010 Author Share Posted June 10, 2010 I tried the regenauto command but that didn't seemed to do anything. Here are a couple more examples This is what it looks like regularly Now this is zoomed in. Notice the solid line appears to turn into a hidden line which is not correct as well. Also two red lines dissappeared. I am also getting an issue with construction lines which I think is the same problem. When I select a point and then start to rotate the construction line to select another point, the construction line appears to be rotating on a different point. Here are the examples Normal construction line This is what happens when I start to rotate the construction line to specify the through point. The line as you see no longer intersects the first point that I specified(in actuality it does but it appears not to) What ever the problem is, I am sure that it is causing all these issues. I tried updating my drivers but windows said that my videocard drivers are up to date. Quote Link to comment Share on other sites More sharing options...
ReMark Posted June 11, 2010 Share Posted June 11, 2010 What are the specs on your video card? What resolution are you using on your monitor? Quote Link to comment Share on other sites More sharing options...
phillyphantom Posted June 11, 2010 Author Share Posted June 11, 2010 my resolution is 1920 x 1080 Is this what you are looking for, for video card specs Quote Link to comment Share on other sites More sharing options...
ReMark Posted June 11, 2010 Share Posted June 11, 2010 I don't see anything amiss. Post a drawing and let one of us take a look at it. Quote Link to comment Share on other sites More sharing options...
Dana W Posted June 11, 2010 Share Posted June 11, 2010 Draw some large circles. If they are not skewed, then the monitor setup is probably OK. I have a 24" WFP monitor that says it is 1080p. My max res setting in my card control dialog goes up to 1680 x 1050, which is the monitor's NATIVE res. Make sure your res is set to the mfg suggested Native res. It has to be for AutoCAD to work on a wide format flat panel monitor. AND somewhere in your video card dialog you should be allowed to select for LOCKED aspect Ratio. You have to do that too. What's with the Directx control? Is that your video card software? I would use whatever software the mfg supplied. In my case, it's Nvidia.

ReMark Posted June 11, 2010 Share Posted June 11, 2010 DirectX is the standard AutoDesk is aiming for. They will be dropping OpenGL. Quote Link to comment Share on other sites More sharing options...
Dana W Posted June 11, 2010 Share Posted June 11, 2010 OK, Dx comes with AutoCAD (and nearly everything else with a GUI) and is installed, but I have no control dialog for it nor can I find one. Quote Link to comment Share on other sites More sharing options...
phillyphantom Posted June 11, 2010 Author Share Posted June 11, 2010 My resolution was the reccommended one, and circles seemed to work fine. As for locking the aspect ration, I haven't found that yet Quote Link to comment Share on other sites More sharing options...
Dana W Posted June 11, 2010 Share Posted June 11, 2010 My resolution was the reccommended one, and circles seemed to work fine. As for locking the aspect ration, I haven't found that yet Look in control panel device manager for the monitor and/or display adapter. There should be some sort of dialog box to monkey around with. That's where I found my controls. It looks to me like your aspect ratio is changing when you zoom, with the shortest lines affected the most, but I could be all wet.

phillyphantom Posted June 14, 2010 Author Share Posted June 14, 2010 I haven't found anywhere to change it yet but I will keep looking. I found something in the Catalyst control center about maintaining aspect ratio but it was grayed out. Quote Link to comment Share on other sites More sharing options...
ReMark Posted June 14, 2010 Share Posted June 14, 2010 Can you post the drawing please? After someone has taken a look at it we'll know if it is the drawing itself or something gone awry with your system. Your monitor uses OSD (On Screen Display) to change settings right?
