curved solid display

[marcocad]

Hi guys, provided I use the 2010 version, I have a solid display problem with curved shapes. I usually draw in meters and realize that lately all shapes with small dimensions give me problems. going to zum any curved shape, you notice the space between the object filling and isolinea (i.e. the design background), especially if the dimensions are small on a measuring unit in meters. you will tell me draw in mm, of course the situation improves but when I have to climb everything to insert it in a drawing in meters and how it drew in meters. I was wondering if you can help me solve this problem since I probably think it's about video card settings. (the facetres variable even at most does not help me so much). I attach an image of a simple 4 cm diameter cylinder and 5 mm high (the size of a gommino for a sofa to draw) to understand what I mean. you will notice the difference between the wireframe view and the other...my goal is to visify objects with realistic shading with the properties of "rotondity" of the wireframe...
thanks guys:smile:

from the help, tools->options->visualization

accuracy of arches and circles
controls the accuracy of circles, arches and ellipses. a higher value produces more accurate objects, but a greater amount of time is required to perform operations such as regeneration, overview and zoom. You can improve performance by setting this option to a low value, for example 100, for drawing and increasing this value for rendering. the valid range is between 1 and 20,000. the default setting is 1000. this setting is saved in the drawing. to change the default setting of new designs, specify this value in the template files on which they are based. (control viewris).

segments in a polylinear curve
sets the number of line segments that are generated for each polylinea curve. The greater the number set, the greater the impact on performance. when drawing, it is advisable to set this option to a low value (e.g. 4) to optimize performance. values are between -32767 and 32767. the default is 8. This setting is saved in the drawing. (splinesegs system variable)

rendering accuracy
controls the accuracy of shady curved solids and renderings. to determine the display mode of solid objects, the value typed for the rendering accuracy option is multiplied by the value corresponding to the accuracy option of strings and circles. when drawing, it is advisable to set the accuracy option subject to rendering a 1 to improve performance. a higher number decreases display performance and increases the time needed for rendering. the valid range is between 0.01 and 10. the default setting is 0.5 and is saved in the design. (changeable facetres system)

Hello! First of all thank you for having responded. . .
As I said in the initial message, I had already put hands on the "facetres" variable without having results...the other 2 did not list them as they act mainly on the wirfeframe display (but still I had changed the settings also of those). . .
the problem as you have seen in the attached image, is the "seated" filling! the isolinees, in fact, are perfect. . .
Do you have any other remedy?
I unfortunately believe more and more that the problem is the video card (I have the nvidia 9500mgs on a notebook), but I hope to be wrong...:frown:
If you have/have other advice, I would be grateful. .

p.s. we cut the head to the bull allego the file... is a very trivial object but we see how you view it...:biggrin:

the video card is not because I also see no crap
I believe it is due to the size, the circle has a radius of 0.00002 units leave to stand mm meters etc.. autocad units.

if the steps immediately see the difference already with radius 0.002 the result is great

Excuse me so much, how do you see the radius of 0.00002??? ?
Look, it's 0.02... or better I set this and I read this... if I went crazy autocad I don't know...:biggrin:
Can you let me know this detail? otherwise install it again

I'm sorry before I'm doing a little bit of evidence. I've been messed up. 0.02 is correct. already with 0.2 but the problem is minimized.

I noticed, but it's strange that a program like autocad gets lost in small size...boh...
cmq thanks shape!!!

the problem is not calculation but visualization. It is normal that it has problems displaying entities whose size is 100 times lower than its unit.

If I can take a consideration... you say that drawings in meters but in fact it is not necessary, or better... the drawing in meters makes sense if drawings highways, but I doubt that making a detail of 0.02 meters is a problem if it is displayed a little segmented if you put it near a chair that is half a meter, in the end it is a dot.

You're perfectly radiant, but I'll tell you what the problem is. I design in meters (a unit considered 1 m and physically set on the autocad document) because I have in most of my work to do besides with buildings, houses etc. their insertion in areas of size in which to use the cm is to become mad. Since, however, in a house I have to insert objects that I am customizing, it makes no sense to draw them in millimeters as since I will have to scale them anyway to inherit them in the plants in meters the sawing of solids will see the same at the time of the scaling. You will tell me, do the reverse procedure, scale in mm the building... this I can do when the project is not complex but not when it has high file sizes. because of this is due to the fact that everything that passes from autocad then I will have to render it on 3ds max. If you use 3ds you know that with heavy files in mm go crazy are really unmanageable...and cmq if you know 3ds you know very well that the curves are a mess even...and the more you elevate the "smooth" the more you put a life to render. ..all here...
I will probably be wrong...but today with all users of autocad and 3ds max with which I relate we did not find a resolute answer to these problemsucci. Somehow imperfections are masked but working times are stretching. . .

in this regard max and autocad try to see if you can help these discussions, we solved otherwise... Try to see.http://www.cad3d.it/forum1/search.php?searchid=945384

Thank you.
great lines are things I know... but I noticed a 3ds parameter I didn't know... now I make attempts... thank you very much.. .

p.s. to close, you always draw in cm or what do you prefer? or better as you like, a unit you mean it as a cm? :biggrin:
the situation changes, however, the files rise:
I wait for the latest news...
thanks shape soon

as you will notice from my profile I design metal carpentry then strictly 1 unit = 1 millimeter and never had problems. Now I have never made a test, but the information that objects have if it is 1 or 0.1 mica change so I don't understand how the file becomes heavier or less.

the smaller a size the more detail to display increases...the better to display it to a resolution that gives rise to a photorealistic image the time to render it increases considerably. ..that was the concept I wanted to express before...(clearly it is my method that over time led me to think so; I never said it was the right one, otherwise I didn't ask for help here:biggrin: )
cmq I really thank you for having responded to the discussion of this theme...
soon
