MR MAN Posted October 25, 2008 Share Posted October 25, 2008 Is There Any Way To Make Circle As Polyline So I Can Make It With Width I Need? Quote Link to comment Share on other sites More sharing options...
tzframpton Posted October 25, 2008 Share Posted October 25, 2008 Don't do that... just start the POLYLINE command, then type A for Arc. when you do that, you can create a circle by simply using your POLAR tracking to make two "arcs". The width should be self explanatory after that. Quote Link to comment Share on other sites More sharing options...
eldon Posted October 25, 2008 Share Posted October 25, 2008 Or go for a Donut, which is a polyline circle with width 1 Quote Link to comment Share on other sites More sharing options...

profcad Posted October 26, 2008 Share Posted October 26, 2008 Use the BOUNDARY command and pick a point inside the circle. AutoCAD will create a polyline on top of the circle. Quote Link to comment Share on other sites More sharing options...
BOB'27T Posted October 26, 2008 Share Posted October 26, 2008 Here's another option Adding global width to a circle Here's a little trick I learned a while back. I needed to add thickness to a circle & found a slick way to do it. Here goes: Start by making a polygon with 4 sides. Check inscribed in circle when prompted. Next specify your radius. That will create a square. Then select polyline edit, then select fit, then width. Tah Dah! You have a circle with a global width! Quote Link to comment Share on other sites More sharing options...
mugshot Posted October 28, 2008 Share Posted October 28, 2008 start w/ polyline, set width. w ( upon your choice) then arc. Quote Link to comment Share on other sites More sharing options...
mugshot Posted October 28, 2008 Share Posted October 28, 2008 or make a polyline that is set upon a width then matchprop the line to your created circle. Quote Link to comment Share on other sites More sharing options...

270 Posted September 25, 2018 Share Posted September 25, 2018 I agree with Bonehead, I prefer the method that profcad offered. Thanks profcad. Quote Link to comment Share on other sites More sharing options...
BIGAL Posted September 27, 2018 Share Posted September 27, 2018 If you did a bit of searching here you would have found a circle with a width and a smart offset. circle - donut.lsp getval2.lsp Quote Link to comment Share on other sites More sharing options...

rkmcswain Posted September 27, 2018 Share Posted September 27, 2018 I did not see this listed, but another alternative would be to draw a polygon with a lot (say 500?) sides. It won't be a true arc or circle obviously, but there may be a case where you need line segments that look like a circle (example: XCLIP) Quote Link to comment Share on other sites More sharing options...
