Why is the line tool forcing me to start at the origin?

Why is the line tool forcing me to start at some random place along what might be the blue axis?

It is not even the blue axis it is just
some random place at the end of a dashed line
WTF?

Can you at least post a screen shot? Or better yet post the skp file you are working on. Otherwise we are guessing. The line tool can start anywhere.
