khoshravan Posted September 5, 2011 Share Posted September 5, 2011 I have a problem with absolute and relative coordinate regarding drawing an arc. From my previous studies, I thought whenever I input coordinates in command line, in order to use absolute coordinates I just enter them. If I want to use relative coord, then I can prefix them with @ sign. For an arc I input as follows: start point: 0,0 2nd point: 500,500 end point: 1000,0. I was expecting to get a half circle from origin to 1000,0 point but to my surprise I find out that CAD gets the input coordinates as relative. Am I missing something? Is this behavior same for all other object drawings? 1.dwg Quote Link to comment Share on other sites More sharing options...
nestly Posted September 5, 2011 Share Posted September 5, 2011 Dynamic Input turned ON = Black Dynamic Input turned OFF = Red Why? .... because the default (OOTB) setting for Dynamic input is "Relative Coordinates" so it automatically adds the @ symbol. If you want to change the default settings, do it through DSETTINGS or use the # symbol to specify Absolute coordinates. Quote Link to comment Share on other sites More sharing options...
khoshravan Posted September 5, 2011 Author Share Posted September 5, 2011 (edited) Dear Nestly Thanks a lot. Like as always your reply is perfect. I have to admit that I was unaware of this point. AutoCad is such a great and detailed program that has commands for every single point. This Forum is really a good place to learn and enhance knowledge about AutoCAD. Just one minor point. You mentioned: Dynamic Input turned ON = Black Dynamic Input turned OFF = Red I didn't get the point where are you referring to? In your posted image I couldn't find your quotes. But my problem is resolved. Edited September 5, 2011 by khoshravan add note Quote Link to comment Share on other sites More sharing options...
nestly Posted September 5, 2011 Share Posted September 5, 2011 "Red" and "Black" refer to the colors of the arcs in your screenshot. Quote Link to comment Share on other sites More sharing options...
