CAD-Method for drawing arbitrary angle lines

Today, we will repeat the old business and Draw Angle lines on the first day to find several ways:

1. Use LISP to change the angle of the cursor.

(Defun C: xxxx ()

(If (setq angg (getreal "\ n, enter the conversion angle <0> :"))

(Setvar "snapang" (* Pi (/angg 180.0 )))

(Setvar "snapang" 0.0)

)

(Princ)

)

After saving, load it to AutoCAD, input snapang in the command line, and then input the angle, the angle of the cursor changes to the Direction

270

180-limit-0

90

2. Right-click "polar axis" and select "Settings". In the incremental corner, select 45 and check the following additional angles, create 10, 20, 30, 45, 60 .......... any angle. After confirmation, it is much easier to draw 10, 20, 30, and other angles.

3. Line

Point to start point

@ 12 <30d30 '30"

Draw a line with a length of 12 degrees 30 degrees 30 minutes 30 seconds
