how to display perfectly round circle in solidworks 1

[froggyscafe]

This may be basic but i have not found the method of doing this. I want to see a close to perfect circle on my screen instead of oblong.

In Autocad there is a method where you draw a circle or a square box. measure the display on screen and enter it. The software adjust to those dimensions so that it displays the image with correct aspect ratio.

thanks

Might have to do this through your monitor's settings. Many people have resolutions that don't fit their screen's aspect ratio and end up stretching the screen's contents to fit the screen window. You can draw a square box within SW and then adjust your monitor until the segments are equal.

I've done this and i end up with about 3/4" of blank space on each side of my monitor. Unused space and it sucks.

Appreciate the posting!

If you get unsed space on your monitior then adjust the monitor and sretch the screen. If I change my resoultion I have black bars on both sides of my screen. I use the buttons on my monitor to adjust it out. I don't know how else to explain that.

What about image quality have you turned that up?

Thinking about your intial post and Theophilus I think he's right and that you need to investigate your monitor for adjustments and try to adjust the software.

Oblong as conpared to "faceted", I would say it was a monitor resolution error as already mentioned. If faceted, then I would look into Document Properties>Image Quality, and crank up the quality.

That should read "I think he's right and that you need to investigate your monitor settings for adjustments and try not to adjust the software."

This is a resolution related "problem".

An example to clarify:

My screen is 400mm long and 300 mm tall. the relation between lenght an height is 1.33333, or 4/3.

My resolution is 1600x1200, wich also gives the ratio 4/3.

This means that any horisontal lenght would be the same actual lenght on screen vertically.

If i change my resolution to 1920x1080 , I get a ratio of 1.777, or 16/9. This means that I squeeze in more pixels on the screen with than on the height, an I get tall oblong
circles.

So, what you should do is to take your ruler and se what aspect ratio your screen is, and pick an resolution that have the same ratio.

general the standard screens ar 4/3, and the resolutions that go with them are: 800x600, 1024x768, 1280x960, 1600x1200, 1856x1392, 2048x1536.

Good luck !

The only caveat from Mindnumbs post is the assumption that the pixels are truly square. Some monitors may not display truly square pixels, since some monitors seem to have a different dot pitch vertically than horizontally.

If that doesn't make sense, please ignore it. The resolution I like using is 1280 x 1024 on both my 19" and 21" ViewSonics. A circle (or square) is almost perfect when I fill my screen at that resolution. Monitors will vary, so if you're very picky about the size, you cannot be picky about wasted screen space unless you get a monitor/resolution compromize that can give you both.

Not to be the one to pick fly crap out of pepper, but there is actually no such thing as a perfectly round circle onscreen.

A circle uses floating point (decimal) math. and this has to be fudged to display using an Integer amount of pixels.

The best you'll get is a series of small, orthagonal dots. From there, it is just a matter of how small you want the dots to be satisfied.

And adding GREY dots (anti-aliasing) does not ioncrease the accuracy, it only makes it more pleasing on the eye.
