Paul, isn't what you are looking for in the display preferences?

I know that if you export drawings and then open them up in Illustrator, you can produce a far higher standard of line.

Hi Tom: Nope, I have the preferences set to super fine :( . I just wondered if anyone else was seeing this effect??...this is a 3point circle 250mm dia that im looking at btw.

Paul, the effect is the same on any circle/ arc tool. I don't think there is anything wrong here, it is just the way that the software displays- in order to make display feedback faster. FWIW, AutoCAD does exactly the same.

Hi Tom: If that is so then Autocad is also wrong !. How would I then know for sure that my curve fits the sample dxf...I wouldnt. I take your point about speed but that is exactly the reason why there are preferences on the display so that it can be throttled back where necessary.

Display for curves should be a walk in the park...thats why I asked the group to see in case it was a video card thing. Im using Nvidia Quadro FX3400 in this kit.

I hope I can imporve this :(

Paul, I think this is a throwback to the days when a 486DX based PC or a 8mHz 68000 Motorola-based Macintosh cost a couple of grand or so, and as you rightly point out, times have indeed moved on.

However if a drawing is dimensioned properly, then there is no need for this accuracy in curvature because you know it's a circle- because it says (Circle) R=xx.x on the drawing (that is of course if the drawing is drawn to ISO BS:8888 standard!), center being xx.x away from vertex x and y etc.

When knocking up sketches drawn at 1:1 and not to scale, it doesn't matter at all how long the piece of string is, just as long as the dimensioning is correct. :)

You missed my point, which is im matching up an imported DXF with an arc so I can create a revolved solid...im working on visual at this stage.

In any case the circle should be drawn 'super fine' right ? thats not what I am seeing my friend.

"My friend"? :eek: That sounds ominous!! :eek: LOL! :D

Okay- whatever......

Actually I think 'super fine' is for solids only. I know that you can change this sketch resolution in ACAD, but I think it is there in VC so that the software can cater for those who don't have NVidia Quattro cards in there computers.

I gotta get myself Shark as I'm badly missing the parametric dimensioning tools of VC :(

A new job starts next week, so hopefully........

Hi, Paul

You have super fine you said but do you have the even distribution boxed check in the edit > change resolution? See Pic.


Have you tried the custom resolution.ini file yet???? see post http://forum.punchcad.com/showthread.php?t=1090

Be careful as the lower the values could possibly have impact on performance.

Hmm- and found a bug...

1. draw a circle,

2. update to 'super fine'.

3. draw line from left circle quadrant to right vertex.

4. Superfine stops being 'superfine', despite still being indicated that it is.

5. uncheck superfine to medium, press okay.

6. recheck superfine, then it stays superfine.

Why didn't it just stay 'superfine' the first time round?

So have cad systems, and viacad will need to improve in its visual output.

Your opinion, and of course you can have that,.. but for me and probably many others, correct accurate visual feedback of what is drawn is a necessity.

The thread is about visual accuracy, not that dimensioning can make it look correct.

As you mentioned string:- if you have a renderer and want to render a model of a piece of string, but it does not look correct, what do you do, have an arrow with a note stating it is a piece of string? or do you look for visual improvement?

I have seen that option, but cannot find a way to make it default for all objects drawn, so then find a need to go to "edit~ change resolution" for each object.

An option I was unaware of, certainly works better (for a circle to look circular), but it still gives inaccurate visuals.

Steve, it's not an opinion, it's a British standard (hence 'BS')- but yes I quite agree with you, I just feel for Tim, that's all (so much to do, so little time as Mr Wonka would say :D )

I dont remember having similar problems with autocad as I see in viacad.

I started with autocad (version2 I think) on a 386sx with co-pro. I could change resolution within the program and that was that. The main problem was the fact I had to give autocad a scale between the xy for the screen resolution so that a circle would look like a circle and not like an oval.

See above bug notice...

I just figured out that you only need to update once- then all entities stay the same (superfine).

I can understand that, and I know that display can be a large time consuming area to improve correctly, but it will need improving eventually.
I would and do prefer that getting rid of bugs is the main priority at this time.

Well perhaps it some stupid input that you have to remember to type into the command line.

I really dislike ACAD, and there is no way that you can really compare ACAD to VC really. VC does so much more for so much less outlay.

Paul, you may like to look at QCad. I sometimes use dxf files outputted from QCad and bring them into VC. It works very well.

I was looking at the option: "even distribution". I think such an option should be made via a global tick box regardless of the actual setting of fine / super fine etc.
