Elliptical Circles

[john.uhden]

I forgot what variable/setting it is to make circles appear visually round, not flattened looking like an ellipse.

I am sure i have a translation problem.
WHAT?

Circles are round if you looking from z-axis of circle.

Or polyon if viewres to low or not regen the screen.

Problem with DXF 210 ?

? Sorry, but i am waiting for the solution, so i know the issue and i can translate your posting well.

No i am off, only following the thread.

I think way back many years ago there was an option within AutoCAD to adjust the aspect ratio, but I suspect now you would do it by way of your monitor's controls.  It would vary with the driver -- on this computer, I right-click in empty space on the desktop and there's a "NVIDIA Control Panel" choice, in which there's a "Display" category with "Adjust desktop size and position" that contains an "Aspect ratio" setting.

[john.uhden]

It's not a VIEWRES issue. A low VIEWRES would make them look like polygons.
My circles look more like ellipses, wider in the X direction than the Y
direction.

Maybe because it's 2002 on a Win10 machine?
Maybe because there's a superfund site down the road?

There is nothing isometric going on here.  Just PLAN;WORLD.

Hi,

I recall doing some mouse and display calibrations in Autocad R12 (or maybe R10...LOL), and also hacking into the phar lap config...LOL, but I'm not sure any more. May be some tube in that 2002 platform it's not functioning, contact a support person from RCA or David Sarnoff labs for more...

Jokes apart, more probably a display driver setting, check the native "resolution" of your monitor and set the display resolution of your system to that value.

Cheers,

Gasty

I tried lowering the resolution, but no improvement.  I recall there was some configuration option as late as R12 (DOS), but I can't remember what it was or if the option exists these days or even for 2002.

Calibration of the screen within AutoCAD disappeared when the Windows versions were released. In DOS it existed as AutoCAD used it's own display drivers, but now everything is handled by Windows.

I assume you have this problem in all drawings and not just one drawing?

If so, it seems to be a probleem with the aspect ratio of the screen settings and if possible you might be able to change it in your Windows display properties or graphic card settings.

[john.uhden]

Thanks, Danny.

There is no aspect ratio setting on this PC's video driver.

I'll try contacting the manufacturer, or start believing that the world is becoming flat.

What DannyNL said.

This reminds me of a colleague i ones had...

He would always complain about monitors not being in correct aspect ratio to show circles as (perfect) circles.

Actually would draw a circle and measure it on screen (with a ruler!) for each new monitor

...but that just might be your only solution, a new monitor

edit:

I don't think modernday flatscreen/LCD's can actually be adapted like the old electron-cannon could... (as it never truly filled the screen but had no pixels, where LCD is a fixed amount of pixels, both horizontal and vertical)

[DannyNL]

Funny thing is that yesterday one of my drafters asked for my help as all circles that he had drawn or copy-pasted seemed to be elliptical. He couldn't really explain why, just that it only happened in one drawing.

After investigating his drawing I found the 'problem'.

I absolutely cannot imagine you didn't think of this yourself or that you have changed this and this is causing the problem, but just to exclude it; UCS?

[john.uhden]

Nope. My circles are ellipses in Plan;World.
Oh, so that's the solution... use an odd VPOINT. Thanks! 😂
