## Make a line with a angle relative to another line

 Hello guys, i'm sorry for the question but i am trying to draw a line with an angle but this relative to another line. How can i do that?

 You can use modify → rotate and choose to keep the original, or make copies.

 In reply to this post by hesediel There is also line → relative angle

## Re: Make a line with a angle relative to another line

 In reply to this post by hesediel it's a good thing if we can have angular "Relative Zero". seems to be easy to implement: 1, relative zero for input polar coordinates; 2, relative zero for output (coordinate widget); 3, an action to change angular relative zero. Before that, we can do the following: To draw a line by an angle relative to to line A: 1, rotate line A to horizontal, keep the old copy; 2, draw a line by angle; 3, rotate the new line from step 2 and line A back, delete old copy; 4, delete duplicated copy of line A. hesediel wrote Hello guys, i'm sorry for the question but i am trying to draw a line with an angle but this relative to another line.

 In reply to this post by ravas i tryied the angle relative but its complicated, puts the line in the middle and several times isnt at the lenght i wrte. the rotate it can work, but then how can i resize the rotated new line at a wanted lenght?

 you can always use "Modify -> Scale" using one end point as reference, and isotropic scaling. hesediel wrote i tryied the angle relative but its complicated, puts the line in the middle and several times isnt at the lenght i wrte. the rotate it can work, but then how can i resize the rotated new line at a wanted lenght?

 Another feature not so difficult to implement: when command widget is activated, *i.e.* user is typing a command: 1, figure out the command is waiting for coordinates (the default), supply coordinates as candidate for command; 2, if user is waiting for angle supply the angle relative to the current relative zero; even easier to implement, create special variables for command line: "xy/cartesian" "theta" for example. dxli wrote you can always use "Modify -> Scale" using one end point as reference, and isotropic scaling. hesediel wrote i tryied the angle relative but its complicated, puts the line in the middle and several times isnt at the lenght i wrte. the rotate it can work, but then how can i resize the rotated new line at a wanted lenght?

 In reply to this post by hesediel Hop; you can respond to a different question.  My Selection does not work.  Only on 'Angle BETWEEN lines'.  What shall I do?  thanks!   gripwin@gmail.com
