Curved lines problem.

[ash87]

I just spent a long time yesterday and today drawing up a basic floor plan of a design i'm working on. There is a lot of curved lines which were all nice and smoothe and fine and i saved my work. Then later on when i opened AutoCAD again, all of those curves arent nice and smoothe now, they are all pointy and look rough.
Does anyone know why this has happened or how to correct it? Will it print off like that? I really dont want to have to start all over again.

Don't worry, just perform a REGEN.

[ash87]

Thank you. I was worried incase i had to start all over again,lol.
Actually i've just opened it up today and its all back to normal- wierd.

Change that number to a higher number. AutoCAD default is only 100 if I remember correctly. I always max mine out at 20,000.

I always max mine out at 20,000.

Why? :unsure:
It's true that the higher the value, the smoother your arcs will be on screen. But that smoothness comes at a cost. In large drawings you may experience longer regen times and sluggish performance when panning and zooming due to the fact that Autocad has to account for that high resolution.

From the Autocad Help files:
Note: Increasing the zoom percentage in VIEWRES may increase the time it takes to regenerate the drawing.
Note: (Setting your resolution via the command line with VIEWRES is the same as going to Options > Display tab).

I'm always working on large drawings so I keep mine set anywhere from 2,000 to 5,000 and my arcs are smooth enough on screen and there is never any unnecessary lag time when panning and zooming.


Will it print off like that?

No. Your resolution on screen has nothing to do with your printed output. A circle can look like a square on screen but will still print as a circle on paper.

...I always max mine out at 20,000.

As Cad64 points out 2,000 should be high enough. I always set it to that in our lab templates and in 10 years have never noticed a need to have it any higher.
The default for viewres used to be 100 up till around 2004 or maybe 2006 when Autodesk finaly realized we were no longer on a 386-16 and upped it to 1000 as the default.

[CADDict]

Why? :unsure:

You know, I've honestly never thought of it. I'll bump it down to about 2,000 and see how happy I am with it.

[ash87]

Thanks everyone. I just changed it to 2000, seems ok so far but im certainly no CAD expert to be able to judge what its like lol.

if i upgrade my video card such as gaming cards, the edges still appear? is there any explanation why the people in autodesk wants this kind of edges always appear?

Your question doesn't make sense to me. Are you trying to start a new question on a new thread?
Can you post a screen capture of the problem?
Not sure what you mean by the people at Autodesk - you can change the settings to whatever you want, not what they want.

viewres
facetres
dispsilh
There are some other things to adjust as well but these are what most people adjust.
Generaly effect the redraw speed. So different people might want different settings depending on the size of drawing, CPU and graphics speed, 2d or 3d... on and on.

Just my 2 bobs worth, I set my viewres as high as I can, because civil drawings are typically not large (1-2 gig), and I never have slow regen problems, but my curves (and there are many in a civil drawing) are always smooth.

:shock: Your drawings are 1-2 gig!? :? Holy Cow! I think the largest dwg file size I've ever seen was around 250mb, and I thought that was huge. Is it because you don't use xref's? :unsure:

A 2 gig file size doesn't even seem managable? You guys must have super computers. :?

That's exactly why I have always had mine set to 20,000. Been that way since I started. I have yet to get a drawing file larder than 5MB and that's with a lot of 3D. No slow regen times ever experienced either.

[Alan Cullen]

Sorry, Cad64, I meant 1-2 Mb (1500 Kb). I always get confused with those numbers. :oops:

And no, we don't use xrefs.

:lol: Ok, that makes a lot more sense.

Yah, as long as you're working with small files you can pretty much set your VIEWRES to whatever you want. I have worked on files in the past that were 50-60mb and had to set VIEWRES lower in order to help speed up Regen time and decrease lag in panning and zooming. Although, I was on a much slower computer back then.

It's just something to keep in mind in case your drawing starts getting laggy.

i see, so the lower the value the faster it goes!!!! thanks JD!

I've experienced the same problem with displaying curved lines. I've tried adjusting all of the settings under the display options, but none seem to have any effect. It's odd that the curves look great in some of my paper space tabs, but not others. It also displays very segmented in my model space. Is there something else I could be missing?

regen enter (or simply re enter)

If you still experience problems attach the file here.

[grimace]

Regen doesn't seem to do anything. Here's the file. If you compare how it displays in model space versus how it displays in the paper space tabs, it is blockier in the model space and it does get worse as you zoom out.

[grimace]

Figured it out.

-Options
-System
-Graphics Display Properties
-Disabled "Adaptive Degredation"
-Increased "Curve Tessellation"
