euncie Posted November 23, 2013 Share Posted November 23, 2013 How can I draw lines with specific interior angles between them? For example, if I draw my first line then, I want to draw the second one but with an interior angle of 100deg between them, what can I do? Thanks.

Dadgad Posted November 23, 2013 Share Posted November 23, 2013 (edited) Welcome to CADTutor forum. Start the line command then use Angles in Autocad are measure by default counterclock wise. You sound like a good candidate for the TUTORIALS link at the top of the page, lots of really good videos and free instruction available.

ReMark Posted November 23, 2013 Share Posted November 23, 2013 If you want to use direct distance entry the format is the distance followed by the angle and it would look like this: @10(units of length) Note the use of the "@" and " Another option would be to use Polar Tracking. A third option would be to reset your crosshairs using the SNAGANG command. Quote Link to comment Share on other sites More sharing options...
euncie Posted November 23, 2013 Author Share Posted November 23, 2013 thanks for the quick response. but, what if the angles that i need to input are the interior angles of the lines? how can i draw using the relative angle? thank you so much.

nestly Posted November 23, 2013 Share Posted November 23, 2013 Unfortunately, there is no way to do it on-the-fly without doing the math, but some of the alternatives are adjusting the UCS to match the existing line, using Copying and using Dynamic Input/Angle Change, or (IMO the easiest) ROTATE with the Copy option. see below.

ReMark Posted November 23, 2013 Share Posted November 23, 2013 Do the math? AutoCAD's default is zero degrees at the 3 o'clock position and all angles measured counter-clockwise. Quote Link to comment Share on other sites More sharing options...
nestly Posted November 23, 2013 Share Posted November 23, 2013 Do the math? AutoCAD's default is zero degrees at the 3 o'clock position and all angles measured counter-clockwise. The OP did not specify, and I'm not assuming the first line is horizontal, so yes, to do it on-the-fly (ie not pausing to change UCS, SNAPANG etc), there would be math involved using the xxx Quote Link to comment Share on other sites More sharing options...
ReMark Posted November 23, 2013 Share Posted November 23, 2013 Dadgad and elton may have addressed that issue in another thread re: relative angles. Quote Link to comment Share on other sites More sharing options...
JD Mather Posted November 23, 2013 Share Posted November 23, 2013 I prefer the Rotate/Copy technique. I prefer to select the line. Click on the endpoint. RMB Copy RMB Rotate enter angle. Quote Link to comment Share on other sites More sharing options...
