help, i have a doubt in draftsight2018 !! I want to draw a line, for example, click on the line icon, then click on any coordinate on the screen, then i orient the crosshair vertically, and write 4.275/2 and enter, and it is supposed to draw a line of 2.1375 length, but it does nothing. any idea on how to set the parameters on system options? or any other settings. i used to draw lines in this way, in draftsight 2015. but in draftsight 2018 i can´t.
