omynn Posted June 27, 2012 Share Posted June 27, 2012 (edited) I draw a curved line and would like it to remain as a curved line even after saving the file. However everytime after saving, and opening the file again, the curve breaks into many line segments, which is not what I want! I want the curved line that I draw to remain as a curved line even after saving and opening. How do I do that? I am using autocad2010. THANKS! I use the ARC command to draw a couple of lines, they look okay here. But after I saved it, and re-open it again, what previously appeared as curved lines changed in their appearance to polyline segments.

ReMark Posted June 27, 2012 Share Posted June 27, 2012 Have you already tried resetting VIEWRES to a higher value such as 2000 or even 5000? Quote Link to comment Share on other sites More sharing options...
SLW210 Posted June 27, 2012 Share Posted June 27, 2012 What are you calling a curved line? (Select it then>Properties) Quote Link to comment Share on other sites More sharing options...

rkent Posted June 27, 2012 Share Posted June 27, 2012 Also set SHADEMODE to 2D. Quote Link to comment Share on other sites More sharing options...

CyberAngel Posted June 27, 2012 Share Posted June 27, 2012 Your display is a rectangular grid of dots that change color. What you are seeing is probably a failure of the graphics system to draw a curve. To cut corners (literally), the video processor will break a curve into several straight segments. At a distance it looks like a curve, and as far as AutoCAD is concerned it is a curve. Setting VIEWRES to a higher number forces the display to increase the resolution, which cuts down on these choppy curves. Technically, if you're not using raster graphics, every curve is drawn as a sequence of shorter segments. These segments may be only one pixel long, but they're still approximations.

nestly Posted June 27, 2012 Share Posted June 27, 2012 WHIPARC Controls whether the display of circles and arcs is smooth. 0 Circles and arcs are not smooth, but rather are displayed as a series of vectors 1 Circles and arcs are smooth, displayed as true circles and arcs Just remember this thread before posting another asking why AutoCAD is so slow.

daft vader Posted June 28, 2012 Share Posted June 28, 2012 Guys maybe its because he needs to just hit refresh like I do, I have the same issue when swopping screens and wondered if it might be that I have not got a very good computer (old like me lol )and hitting refresh then shows the curved lines correctly, the drawings always print correctly BTW ? so its not that its draw wrong just displayed incorrectly on my machine ?

I agree, how it displays may be distracting, but it is merely how it is represented, when printed it will be a continuous curve. Quote Link to comment Share on other sites More sharing options...
