Draw a Line given 1 point and an angle

[tany0070]

hi all, like to ask is anyone has any method of ploting a straight with just 1 given point and an angle. don't need to be a code, if you have some interesting algo to get a rough 2nd point to use command "line", i also would like to know. thanks in advance

Depending what version of Acad you are using you can do this using the polar tracking, you would just need to edit the angle settings to what you require.

Have a look at the POLAR function.

At autocad command prompt enter @distance<angle

Command: line
LINE Specify first point:
Specify next point or [Undo]: @10<135

draws a line 10 units long at 135degs

that's new (at least for me). thanks

oh just a thought, if the angle is on the ending plane(i.e. the side i want to reach) is it possible to draw the line?? it's like i want to draw a line from a point to a line, the position of the line is unknown but i know this line will touch this point at an angle. thanks
